Show HN: Purpose Reminders – One simple, positive act emailed monthly to all https://bit.ly/45yRpg0

Show HN: Purpose Reminders – One simple, positive act emailed monthly to all Hi HN, I built Purpose Reminders ( https://bit.ly/43GszIC ). Our first monthly action – "Leave a positive review for a local business" – goes out June 1st (very soon!). The core idea: What if thousands of us did the same small, positive act each month? You get one email, choose to act or skip (no pressure), and then see the collective, anonymous impact. It's 100% free, built with Next.js/Supabase/Resend. My attempt at a simple way to foster some collective goodwill. What do you think of the concept? https://bit.ly/43GszIC May 31, 2025 at 10:51PM

Show HN: MCP Defender – OSS AI Firewall for Protecting MCP in Cursor/Claude etc. https://bit.ly/43ROz4t

Show HN: MCP Defender – OSS AI Firewall for Protecting MCP in Cursor/Claude etc. Hi HN, MCP Defender is an open source desktop app that automatically proxies your MCP traffic in AI apps like Cursor, Claude, Windsurf and VSCode. It then scans all requests and responses between the apps and the MCP tools they call. If it detects anything malicious, it alerts you and lets you allow or block the tool call. While the threat landscape of MCP is still being actively researched, there are dangerous things that MCP Defender can block today. For example, a developer asks Cursor to fix a Github issue with an attached crash log. However, the Github issue was created by an attacker who included secret instructions buried in the crash log. These instructions tell Cursor to send the developer’s SSH keys to a server the attacker controls. MCP Defender detects these malicious instructions and alerts the developer who otherwise may not be careful in running tool calls. The scanning is currently done via an LLM and checks for things like prompt injection, credential theft (ssh keys, tokens) and arbitrary code execution. You can use an MCP Defender account or provide your own API keys for LLM providers to perform the scanning. Currently we’ve published a beta Mac build and we’ll soon publish builds for Windows and Linux as well. Any feedback would be greatly appreciated. Thanks! https://bit.ly/452LQXg May 29, 2025 at 06:40PM

Show HN: Smart Silence – Remind your iPhone to stay quiet in quiet places https://bit.ly/4mFdVdi

Show HN: Smart Silence – Remind your iPhone to stay quiet in quiet places Hi HN, I built an iPhone app called *Smart Silence* after sitting in a quiet setting (a service, actually) where someone’s phone rang loudly and interrupted everything. It wasn’t intentional — just one of those forgetful moments. I started wondering: what if our phones could gently remind us to stay silent when it matters? *Smart Silence* helps iPhone users do just that. It lets you: - Mark places where silence is expected (like libraries, meetings, classes, or houses of worship) - Get a reminder when you enter, with an easy Shortcut to enable Do Not Disturb - Schedule quiet times (e.g. “Mondays 9–11am at this place”) - Share Silent Places with others — so your community, school, or workspace can use the same setup - Stay fully in control — no auto-silencing, and no location tracking outside of defined zones It’s currently available via TestFlight: https://apple.co/4kj9CTl I’d love feedback — especially around usability, edge cases, or features you’d expect. If you run or attend a place where silence matters, I’d love to hear your thoughts. https://apple.co/4kj9CTl May 28, 2025 at 02:51PM

Show HN: Changefly – Rebuilding the foundation of privacy and authentication https://bit.ly/4dEJ3FX

Show HN: Changefly – Rebuilding the foundation of privacy and authentication Lukas here, founder of Changefly. For those of you who might remember neworder.box.sk and astalavista.box.sk, I was one of the admin's at a very young age. Fast forward to 2018, I set out to help people regain their privacy. Google invited us into the Google Cloud Startup program which led to the creation of Changefly. After years of truly challenging work and thousands of iterations, Changefly ID was born. Changefly ID solves the problem both users and companies face on a daily basis... spam, scams, bots, account takeover attacks. At face value it looks like an ordinary code, but in fact, it is an encrypted security code that only the user knows and has access to use (a distributed anonymous authentication code). Changefly ID has a lot of flexibility -- replace traditional authentication (which you absolutely should do) or use secondary for multi-factor authentication (a good stepping-stone). It also includes end-to-end communications with your users through Changefly (not email, sms, or other unsecured channels). Additionally, the Changefly app data is also end-to-end encrypted as is the local data. We made access to Changefly ID easy and free with our Developer API. Changefly ID really does stop bots, spam, scams, and other threats from getting anywhere near users or their accounts. p.s. A big thanks to Tom (HN moderator) for their help! https://bit.ly/3HhDX6l May 30, 2025 at 09:47PM

Show HN: Donut Browser, a Browser Orchestrator https://bit.ly/4dFjGDS

Show HN: Donut Browser, a Browser Orchestrator Hi HN, I'm excited to share my open source project, a browser orchestrator. It's purpose is to make it easy to manage many browser profiles on one system. Currently it only works on MacOS, but since I've built it using Tauri (which is a Rust backend and TypeScript frontend), I expect to add Linux and Windows support in the future. I've built it primarily for myself as I use a lot of browsers and having an easy way to manage all of my profiles would make (have made, actually) my dock less cluttered haha. Also, part of why I built it is because as someone who doesn't really care about anti-detect features (which I might support in the future), I don't understand how they cost so much for a very limited number of profiles in pretty much all anti-detect browsers. I feel like a lot of people feel the same and will cover their use cases with my free tool. If you try it, please share your feedback! I haven't seen any open source projects like this and want to learn more about how people might use it. https://bit.ly/4kGN2E8 May 30, 2025 at 05:09AM

Show HN: I'm starting a social club to solve the male loneliness epidemic https://bit.ly/3ZalYVA

Show HN: I'm starting a social club to solve the male loneliness epidemic The other day I saw a post here on HN that featured a NYT article called "Where Have All My Deep Male Friendships Gone?" ( https://bit.ly/4mEqntY ) and it definitely hit home. As a guy in my early 30s, it made me realize how I've let many of my most meaningful friendships fade. I have a good group of friends - and my wife - but it doesn't feel like when I was in college and hung out with a crew of 10+ people on a weekly basis. So, I decided to do something about it. I’ve launched wave3.social - a platform to help guys build in-person social circles with actual depth. Think parlor.social or timeleft for guys: curated events and meaningful connections for men who don’t want their friendships to atrophy post-college. It started as a Boston-based idea (where I live), but I built it with flexibility in mind so it could scale to other cities if there’s interest. It’s intentionally not on Meetup or Facebook - I wanted something that feels more intentional, with a better UX and less noise. Right now, I'm in the “see if this resonates with anyone” stage. If this sounds interesting to you and you're in Boston or another city where this type of thing might be needed, drop a comment or shot me an email. I'd love to hear any feedback on the site and ideas on how we can fix the male loneliness epidemic in the work-from-home era. https://bit.ly/3Hvw11b May 30, 2025 at 12:57AM

Show HN: Clean Simple DNS Lookups https://bit.ly/43D71fW

Show HN: Clean Simple DNS Lookups Hey HN, Last weekend I vibe-coded a cool website that lets you do easy DNS record lookups. I know you can just use dig or nslookup, but oftentimes I'm too lazy to remember the syntax, and there are less technical users who need to manage DNS entries but aren't comfortable with the command line. We debug customer DNS issues often at ImprovMX, and we typically link to tools like mxtoolbox.com to point out DNS record issues. But those tools seem quite bloated and from the 2000s. I wanted something super clean & simple, and there were a few features I thought were ergonomically needed but lacking: - no confusing dropdowns or syntax for DNS lookup, just put in your domain or subdomain - click-to-copy for all values - header-links so we can provide URLs that will direct another user to an exact domain and which record we want to reference This was SUPER FUN to vibe code! The frontend was pretty much one-shotted with lovable. It's amazing how good AI is when working on a clean slate with all the latest popular frameworks (react, tailwind, shadcn, etc.). And I spent the next few hours making small tweaks with cursor. The backend is a dead simple python flask server. Both are hosted on render.com <3 I love how simple and value-oriented render.com is. It's always the provider that gives me the least headache when I want to just launch and forget something. Give it a try and let me know what you think! https://inspector.improvmx.com May 29, 2025 at 07:51PM

Show HN: Typed-FFmpeg 3.0–Typed Interface to FFmpeg and Visual Filter Editor https://bit.ly/4mBkTjB

Show HN: Typed-FFmpeg 3.0–Typed Interface to FFmpeg and Visual Filter Editor Hi HN, I built typed-ffmpeg, a Python package that lets you build FFmpeg filter graphs with full type safety, autocomplete, and validation. It’s inspired by ffmpeg-python, but addresses some long-standing issues like lack of IDE support and fragile CLI strings. What’s New in v3.0: • Source filter support (e.g. color, testsrc, etc.) • Input stream selection (e.g. [0:a], [1:v]) • A new interactive playground where you can: • Build filter graphs visually • Generate both FFmpeg CLI and typed Python code • Paste existing FFmpeg commands and reverse-parse them into graphs Playground link: https://bit.ly/3FDlwZ8 (It’s open source and runs fully in-browser.) The internal core also supports converting CLI → graph → typed Python code. This is useful for building educational tools, FFmpeg IDEs, or visual editors. I’d love feedback, bug reports, or ideas for next steps. If you’ve ever struggled with FFmpeg’s CLI or tried to teach it, this might help. Thanks! — David (maintainer) https://bit.ly/45hvlqr May 29, 2025 at 05:23AM

Show HN: AutoThink – Boosts local LLM performance by 43% with adaptive reasoning https://bit.ly/4dCoQAy

Show HN: AutoThink – Boosts local LLM performance by 43% with adaptive reasoning I built AutoThink, a technique that makes local LLMs reason more efficiently by adaptively allocating computational resources based on query complexity. The core idea: instead of giving every query the same "thinking time," classify queries as HIGH or LOW complexity and allocate thinking tokens accordingly. Complex reasoning gets 70-90% of tokens, simple queries get 20-40%. I also implemented steering vectors derived from Pivotal Token Search (originally from Microsoft's Phi-4 paper) that guide the model's reasoning patterns during generation. These vectors encourage behaviors like numerical accuracy, self-correction, and thorough exploration. Results on DeepSeek-R1-Distill-Qwen-1.5B: - GPQA-Diamond: 31.06% vs 21.72% baseline (+43% relative improvement) - MMLU-Pro: 26.38% vs 25.58% baseline - Uses fewer tokens than baseline approaches Works with any local reasoning model - DeepSeek, Qwen, custom fine-tuned models. No API dependencies. The technique builds on two things I developed: an adaptive classification framework that can learn new complexity categories without retraining, and an open source implementation of Pivotal Token Search. Technical paper: https://bit.ly/3Z31NJ2 Code and examples: https://bit.ly/3Sm2LMT... PTS implementation: https://bit.ly/4kbUxCZ I'm curious about your thoughts on adaptive resource allocation for AI reasoning. Have you tried similar approaches with your local models?

Show HN: Weather2Geo – Geolocate screenshots from weather widgets https://bit.ly/45wVSzV

Show HN: Weather2Geo – Geolocate screenshots from weather widgets Hi HN, I built an OSINT tool called Weather2Geo that helps locate where a screenshot was taken based on the weather widget data visible (e.g. temp, condition, and local time in the taskbar). People often post these without realizing how specific those values can be in combination. It works by comparing the given weather condition, temperature, and time against current data from thousands of cities. It’s timezone-aware, supports fuzzy matching, and groups results geographically to reduce noise. It’s most effective on recent screenshots, ideally taken within the last hour—since weather and daylight conditions change quickly. The tool helps pinpoint likely locations when screenshots lack EXIF data or other traditional OSINT clues. It’s open source here: https://bit.ly/44WfzB2 Would love feedback, bug reports, or to hear if you think this has other use cases. - Elliott https://bit.ly/44WfzB2 May 27, 2025 at 11:31PM

Show HN: Millau – self-configuring ingress proxy for Docker Swarm https://bit.ly/4dAa9xS

Show HN: Millau – self-configuring ingress proxy for Docker Swarm I still use Docker Swarm. It's simple, fast to set up, and easy to teach. But I got tired of managing routing to microservices. Nginx and HAProxy need config redeploys, Traefik is powerful, but its configuration via labels quickly becomes unmaintainable. So I built Millau — a free ingress proxy and load balancer for Docker Swarm microservices. Add a few labels to the service, and traffic gets routed. No proxy restarts, no config files. Example: ``` # service deploy: labels: - "millau.enabled=true" - "millau.port=9000" ``` Millau listens to Docker events, discovers labeled services, and routes traffic using host and path matching. Unlike Traefik, Millau supports load balancing across services. I use it to deploy different versions e.g. Blue, Green, Red of the same microservice. If Red crashes, Millau routes to Blue or Green. If Blue slows down, Millau marks it inactive for 60s and routes to Green. Millau supports TLS termination and mTLS. It exposes Prometheus metrics and ships with a prebuilt Grafana dashboard. It's in production, serving its own site and several side projects. Let me know what you think, especially if you're still using Docker ecosystem in prod. Thanks. https://bit.ly/3Zq2gW3 May 26, 2025 at 10:15PM

Show HN: I built an AI image tool solo in 1 month Hey HN! Over the past month, I built Styleloop, a solo side project that uses AI to transform images into stylized artworks. The primary focus is image-to-image transformation, with curated styles like Ghibli, pixel art, Animal Crossing, and more. It’s my first real SaaS project, and honestly, the process changed how I think about building and shipping products. From backend to payments to UI polish — doing it all solo was exhausting and incredibly rewarding. Styleloop was built with Next.js, Supabase, Stripe, and Cloudflare. I plan to keep improving it and add more creative modes. I'd love your feedback on whether you’re into AI x creativity or solo hacking projects!

Show HN: Manifold is a platform for workflow automation using AI assistants https://bit.ly/3ZnXeJF

Show HN: Manifold is a platform for workflow automation using AI assistants Hi HN! I'd like to show an early version of Manifold. This is a flow based UI (think ComfyUI) for designing automated workflows using language models. This is a passion hobby project and not intended for production use. The idea behind it was, can we create "the last tool"? A platform that can create any other computing tool or execute a process by designing workflows visually, and having AI assistants generate the necessary code or data with each run? Here is a list of some of the more notable features: - Supports public endpoints such as OpenAI API, Google and Anthropic completions, as well as any OpenAI API compatible local backend. - Integrated RAG solution that leverages PGVector for semantic search as well as an inverted index (keyword search) with multiple document merge modes. Option to retrieve full documents or chunks. - ReAct Agent with access to configured MCP servers. If no suitable tool is found, the agent is instructed to generate their own in a secure code sandbox. - Integrated web code editor that runs code in a WASM sandbox with support for JavaScript, Python or HTML previews. - CodeRunner node that supports third party libraries in a local container sandbox. Python, JS and Golang are supported. Libraries are automatically installed. - Nodes to control the execution flow of your workflow. Run concurrent agents. Jump to nodes. Execute for each loops on assistant outputs. Combine context. Publish and subscribe to topics to teleport context around your workflows. Documentation is non-existent but I am working on that before a formal 1.0 release. Expect bugs. Manifold is 99% a solo developed project with the help of a very much appreciated contributors. This is an open source project. Given the scope, I am sure I have overlooked many important things. Feel free to reach out to me if you have suggestions, or if there is a glaring issue that needs to be fixed. The README has multiple images of example workflows for your viewing pleasure. Hopefully those give the community an idea of what is possible when creatively combining the nodes. The repository is located at https://bit.ly/44UiNF4 . I appreciate any constructive feedback and contributions. https://bit.ly/44UiNF4 May 25, 2025 at 02:00AM

Simple description of algorithm: * Take complicated document such as pdf or html, and created a simplified representation for it as a list of a list of dicts where each dict is a text block with key features such as "bold", "font-size", etc and each line represents a new html block or line on a pdf. * Convert the simplified representation to a dictionary using a set of predetermined rules, e.g. smaller font-size for a heading means it should be nested under the larger font-size heading. Note that I am working on making the last part more modular by creating predetermined instructions that users can tweak for their use-case without rewriting the parser. I call these "mapping dicts". doc2dict also includes visualization tools for the debugging process: * visualize simplified representation https://bit.ly/43AmwFB... * visualize output dictionary https://bit.ly/43AmwFB... Why I made this: I'm currently working on another open source python package to make it easy to exploit Securities & Exchanges Commission data. Writing a generalized document parser that can be tweaked is easier than writing 100 or so specialized parsers for each document type. Also, converting html and pdf files to dictionary representation reduces document size by a factor of 10 or so. Not sure what I can do with that, but planning on some fun NoSQL database experiments.

Show HN: Display any CSV file as a searchable, filterable, pretty HTML table I combined this with a simple API to update a CSV file using Deno/deno-csv library, allowing an Ansible job to easily update a CSV file via the API with Ansible URI module, and then have that same CSV file viewable/downloadable in a simple and easy/dashboardy way (with CSV-to-html-table). Copilot created the Deno/deno-csv CSV API code and then with a little back and forth I added static website functionality (to serve the CSV table), and I had a /view and a /update route. I'm just a sysadmin but I love piecing together stuff like this. Thanks Derek! https://bit.ly/3Zte6hT May 22, 2025 at 01:31AM

Show HN: I made a word puzzles app for improving your English vocabulary English is my second language. From my experience, I learnt that developing your vocabulary is a long and arduous process. Traditionally, learners used flashcards (or their digital incarnations). I wanted to build something more engaging and more effective in building your vocabulary. DictionaryGames is aimed mostly at ESL (English as a Second Language) students, but I am hoping it might be fun for any English language lovers. The project is in BETA, it is free, and no registration is required. I am looking for feedback to improve it. If you comment, please indicate if you are a native English speaker. I am in particular interested in the feedback from ESL learners. https://bit.ly/4drtelP May 18, 2025 at 12:17AM

Show HN: Near-perfect English AI translation of a classic of Japanese literature https://bit.ly/3H3riUv

Show HN: Near-perfect English AI translation of a classic of Japanese literature Recently I launched BookTranslate.ai but at launch there wasn't really anything to see on the site. I should have thought about creating public demos before I launched, but now I added a few, including this one. I ran a blind analysis on the translation with Gemini: https://bit.ly/3Ztni5R... This is huge, in my opinion. I don't mean it to brag or sell, I mean it as a matter of fact that no other software can produce this level of quality right now and people thought machine translation will never be capable of this. I'm constantly amazed by how good the output of this system is and I have barely been able to sleep because of the excitement for days haha There is another full book demo on the site too, a non-fiction french to english translation of a 19th century political philosophy book which is similarly amazing in terms of quality: https://bit.ly/4krngDK... It rivals any human translation, and frankly, I've been in the publishing business for a decade and I can say it blows away half of them because there is so many bad translation out there in the bookstores. Sorry if I sound salesy. I don't think ppl here are much interested in buying book translations anyway, its just that I genuinely think this is a gamechanger for the whole industry. A translation like this takes about an hour or two btw. https://bit.ly/3ZtniTp May 20, 2025 at 02:25AM

Show HN: Grace – Orchestrate Hybrid Mainframe and Cloud Workflows with YAML https://bit.ly/4dobp6V

Show HN: Grace – Orchestrate Hybrid Mainframe and Cloud Workflows with YAML Hi HN, I'm a CS student and intern at the California DMV. I’ve spent the last few months migrating mainframe datasets (mainly VSAM KSDS) into cloud systems like RDS/Postgres — and I kept running into the same problem: there's no sane way to orchestrate workflows across mainframe and cloud systems. Everything is fragmented: - Mainframe teams write JCL and use job schedulers - Cloud/data teams build Python ETL scripts and Airflow DAGs - Integration is slow and manual, often extensive email threads and handoffs between siloed teams So I built Grace, a declarative orchestration toolchain that lets you define end-to-end workflows in YAML, from COBOL batch jobs to S3 uploads or shell scripts. https://bit.ly/3GZNiQ9 Grace handles job orchestration across environments, including JCL templating and submission, dataset transfer, inter-job data handoff, and structured logging for each step. The goal is to expose mainframe logic in atomic, reusable steps that can be integrated into modern infrastructure pipelines. Mainframes will be around for decades to come. I don’t think rewriting millions of lines of COBOL is a good use of time or money; the real need is tooling that allows cloud-native systems to hook cleanly into legacy logic. Grace aims to be that bridge: a shared control plane for orchestrating hybrid infrastructure, without the glue code. Would love feedback from anyone working in legacy modernization, DevOps, or infra. https://bit.ly/4dkb5Gi May 19, 2025 at 02:53AM

Show HN: Job board aggregator for best paying remote SWE jobs in the U.S. https://bit.ly/4jet82e

Show HN: Job board aggregator for best paying remote SWE jobs in the U.S. I’ve been a remote SWE since the pandemic and truly appreciate its flexibilities and time saved from not commuting. Lately, friends and close ones have been asking me for advice on finding remote roles. I shared my remote company spreadsheet with them, but realized it was a rather manual process to scroll and refresh each company’s career page for new postings. So I put together a centralized job board aggregator that lists the best paying SWE jobs in one place, starting with the U.S. and 14 companies. The way it works is via a cron job that runs daily in the afternoon to pull the latest job postings from each company and updates the website with the new listings. Some other key features are 1. Quickly see which companies are actively hiring, e.g. Coinbase currently has the most openings 2. Filter by years of experience or companies to find suitable matches 3. Easily see estimated salary and posted date If you're also on the hunt for the next remote SWE role, I hope this site helps streamline your job search and would appreciate any feedback and suggestions.

Show HN: I built an AI sales agent that writes and sends cold emails for you Hey HN, I’ve been working on ElevateSells — an AI sales agent designed to take the pain out of cold outreach for solo founders and small teams. Here’s how it works: You ask the AI to generate leads or manually use the advanced lead search built in tool. You tell the AI what your business does and what problem it solve. It writes very personalized cold emails, sends them, and follows up — all automatically. You still control the voice and audience — the AI just handles the research, writing, timing, and sending. I built it after burning out managing multiple tools for lead gen, email copy, and follow-up. I just wanted one simple system that actually got replies — and sounded like a human. ElevateSells is now live and running — no waitlist, no fluff. Try it here: https://bit.ly/3S6CVfH I’m happy to answer questions, share feedback, or walk through how I built it. Thanks!

Show HN: Hyprsqrl – open-source revolut you can self-host (live iban/sepa/ACH) Hi HN! Ben here from hyprsqrl, and I just open-sourced something we’ve been quietly running in production: *hyprsqrl is a self-hostable bank. Think Revolut (if you know it), but every line of code is MIT/AGPL, you can run it on your own box, and the crypto bits stay hidden under the hood. --- ### Why we built it Moving money between USD and EUR still means wire fees, surprise freezes, and “call your bank” hoops. Fintechs like Revolut help—until their pricing changes or a regulator knocks. hyprsqrl aims for the resilience of self-hosting *without* forcing users to study crypto. Two recent shifts made that finally doable: * *wallet abstraction UX is catching up*—passkey login support is coming next week (good-bye seed phrases) * *one-API on/off ramps* (AlignLabs today) let us bridge SEPA ↔ stablecoin and ACH ↔ stablecoin cheaply Right now we lean on Privy for auth + wallet orchestration, but the plan is to drop it as soon as passkeys land and minimize third-party dependencies across the board. --- ### What’s live today * IBAN & SEPA inbound → auto-minted USDC/EURC on-chain * ACH payouts (live AlignLabs environment) * Next.js dashboard for balances, transfers, audit log * In production moving real money since May 2025 --- ### What’s next * *passkey auth* replacing Privy (in review) * *earn module* (yield on idle balances) nearly done * *pots / budgeting allocations* work but getting another design pass * extra fiat ramps for redundancy * smoother one-click self-hosting (docker works now but could be simpler) --- ### How to try it * GitHub: https://bit.ly/4diaEfI * Live app: https://bit.ly/4k2qca4 — spin up a IBAN/ACH in seconds Self-hosting still painful, but the rails are live—give it a whirl! https://bit.ly/4diaEfI May 15, 2025 at 11:54PM

Show HN: Booktranslate.ai – Recursive AI Translation Engine for Full Books https://bit.ly/3YKzZcn

Show HN: Booktranslate.ai – Recursive AI Translation Engine for Full Books Hi all - I’m an indie dev and publisher who’s spent years manually translating books. I finally got tired of it and built BookTranslate.ai - a recursive, glossary-enforced, multi-pass AI translation system designed specifically for full-length books (nonfiction, essays, philosophy, etc., probably not good enough for fiction though). It runs each paragraph through several passes with a sliding context window (previous few paragraphs) to maintain tone and coherence. Glossary terms are strictly enforced mid-prompt, and formatting is preserved. It’s kind of like a lightweight RAG-style workflow, but prompt-orchestrated instead of vectorized. It outputs ~98% publishable translations, even in languages like Chinese, Japanese, and Arabic. I’ve used it to translate libertarian works to Hungarian and forgotten Hungarian free market economists to English, and people never even guessed it's almost all AI. No hallucination, no over-polish, and a really high rhetorical fidelity. I couldn't really find anything that comes even close to what this system produces in translation quality. Would love feedback about it! AMA! https://bit.ly/4md9PJn May 15, 2025 at 05:01AM

Show HN: Sauron MCP – one MCP to rule them all https://bit.ly/43wi3Vt

Show HN: Sauron MCP – one MCP to rule them all After spending some time exploring MCPs, I realized there’s a serious lack of infrastructure — especially when it comes to remote MCPs. Right now, the process of discovering a tool online, installing it locally, and restarting your environment (e.g., Claude Desktop) just to try it out feels clunky and outdated. So I built SauronMCP — a single MCP that can search for and proxy remote MCPs without requiring local installation. You simply ask Sauron to find and use the tool — it handles the rest. No restarts, no manual setup. This is very much an MVP, and I'm not a security engineer — so if you have thoughts on potential risks or ideas for improving the architecture, I’d love your feedback. https://bit.ly/4miGmNZ May 15, 2025 at 01:07AM

Some key features: Voice-only practice (no need to look at your screen) AI evaluation & feedback Practice publicly available lists or upload your own excel lists. Publish your lists for others to use Uses the SM2 algorithm to manage repetition scheduling Tech stack includes Swift, Firebase, Deepgram, ElevenLabs, and OpenAI (trying various models) I’d love feedback from fellow learners, developers, or anyone interested in voice interfaces. Especially if you’ve built language tools before — I’m curious about what would make this more useful or sticky.

Show HN: I built a simple AI-powered ATS for small teams Hi HN, I'm Rajath. I built Applisights after seeing startups use Google Forms for hiring, only to shut them down hours later after getting flooded with applications. The problem: Small teams often struggle to manage job applications efficiently. Existing ATS solutions are bloated with features, require training, and come with complex setups. On the flip side, makeshift tools like Google Forms and email create disorganized workflows, making it hard to track candidate progress. The solution: I built Applisights to be an AI-powered ATS you can just start using right away, with no complex setup or training needed. It automates resume intake, uses AI for intelligent screening, and helps you track candidates in a clean, intuitive interface.

Show HN: AGI Hits a Structural Wall – A Billion-Dollar Problem https://bit.ly/3RY9Oer

Show HN: AGI Hits a Structural Wall – A Billion-Dollar Problem This paper formally defines where current AGI hits a structural wall — not a technical one. It shows that no amount of scaling, reinforcement learning, or recursive optimization will break through three deep epistemological and formal constraints: 1. Semantic Closure — An AI system cannot generate outputs that require meaning beyond its internal frame. 2. Non-Computability of Frame Innovation — New cognitive structures cannot be computed from within an existing one. 3. Statistical Breakdown in Open Worlds — Probabilistic inference collapses in environments with heavy-tailed uncertainty. These aren’t limitations of today’s models. They’re structural boundaries inherent to algorithmic cognition itself — mathematical, logical, epistemological. But this isn’t a rejection of AI. It’s a clear definition of the boundary condition that must be faced — and, potentially, designed around. If AGI fails at this wall, the opportunity isn’t over — it’s just starting. For anyone serious about cognition, this is the real frontier. Full paper: https://bit.ly/4kjr2z6 Open to critique, challenge, or counterproofs. May 13, 2025 at 12:57AM

Piny doesn’t try to be all-in-one visual editor that would cover layout creation, styling, data, logic… That is no longer relevant in the age of AI coding agents. Instead, Piny focuses on two areas where it can really add value: # Tailwind styling Piny lets you easily style JSX / HTML with Visual Controls and Class Inspector (an editable tree view of all classes and states). This also works with any strings that contain Tailwind classes. For visual tasks (such as changing the text size) it is often much easier to directly change a visual property than to go back and forth about it with your AI agent. # Project navigation Navigate the project code by selecting elements directly in the built-in browser preview. Just click on a heading, image, icon, section etc in the preview and its source element is selected in Piny and in the code. This feature requires a small dev-only script to be inserted into the layout. React with Vite, any Next.js and Astro projects are supported at this time. Piny is based on Pinegrow Web Editor, our desktop visual editor for static HTML & WordPress that we’ve been actively developing for more than a decade. This makes Piny feature complete and robust, it’s not a MVP. # Piny Free and Pro The standard edition is completely free. You don’t even have to sign up. Just install it from the extension marketplace and you’re ready to go. Piny Pro adds Visual select (Project navigation, mentioned above), custom Tailwind theme import and other goodies. We’re running an Early Access deal with 60% discount that you get to keep forever. # Visual tools in the age of AI A lot has changed in web development. When Pinegrow was launched here on HN 11 years ago, Bootstrap was a shiny new framework. Today, visual tools should be designed to complement AI assisted development. This principle is reflected in Piny: - It runs in your IDE, where you already work - All changes happen in the code - Uses visual tools for visual tasks - Helps you jump to the relevant component / element in the code so that you can then edit it visually, in code or with AI - Piny is there when you need it and gets out of your way when you don’t # Getting started To take Piny for a spin, install it from extension marketplace, right-click anywhere in your code and choose “Edit in Piny”. Pro trial version is included if you want to try Visual select. Let me know if you run into any issues, or just want to get in touch! https://bit.ly/3GN8vg0 May 10, 2025 at 02:22AM

Show HN: Woxi - A Rust-based interpreter for a subset of the Wolfram Language https://bit.ly/43kHIjM

Show HN: Woxi - A Rust-based interpreter for a subset of the Wolfram Language Mathematica is an incredible piece of software, and the Wolfram Language is actually quite pleasant to use once you get used to the syntax. Unfortunately, the high licensing costs of Mathematica make it inaccessible to many people, and therefore (in my opinion) worse solutions like Python, R, and Jupyter have become the default. Due to the sheer size of Mathematica (over 6000 functions!), it is impossible for me to rebuild it from scratch alone. Please join me in rebuilding it one PR at a time so we can finally make it accessible to everyone! https://bit.ly/4m3tg7n May 8, 2025 at 09:59PM

Show HN: Koodi – A PWA that aggregates USSD codes for African telecom users https://bit.ly/42TdeWc

Show HN: Koodi – A PWA that aggregates USSD codes for African telecom users Hi HN, I’m a developer based in Togo, and I recently built a small tool called koodi.africa, a Progressive Web App that aggregates USSD codes (used to check balances, buy data, send money, etc.) for telecom users in Africa. In many African countries, users rely on USSD codes for everyday mobile money actions and data purchases—but it’s hard to remember all the codes across different networks and countries (Moov, MTN, Yas, Orange, etc.). So I created koodi.africa as a simple, installable web app that lists these codes in an easy-to-use interface. You tap a button (e.g., “Buy 500MB data”), and it launches the correct USSD code. It even handles variables if needed. It works offline after the first load, so it’s usable without an internet connection. Great for people who travel, use dual-SIM phones, or manage multiple numbers. This is just an MVP – built in a few hours – but I’d love feedback, feature suggestions, and contributions. Try it here: https://bit.ly/4dfsXlY Happy to answer questions! https://bit.ly/3ZbqNOa May 8, 2025 at 10:03PM

Show HN: YouTube Time Machine – browser extension to find forgotten videos https://bit.ly/3GHJh2A

Show HN: YouTube Time Machine – browser extension to find forgotten videos I built this after reading about YouTube's 20th anniversary and learning that the median YouTube video has only 41 views. The extension searches for videos with default camera filenames (DSC_, IMG_, GOPR, etc.) that people uploaded without SEO optimization. In YouTube's early days, people weren't trying to become influencers - they just wanted to share moments. These videos give an authentic glimpse into people's lives without the "like and subscribe" calls to action. The extension only searches public videos. You can choose a camera model and date to see unfiltered snapshots of life that the algorithm has overlooked. The day and month of the date is used as the four digits. It's a reminder of what YouTube was before it became "the new Hollywood." Built it in ~90 minutes with some AI assistance. Code is on GitHub if you want to contribute or modify. https://bit.ly/4k6OS0E May 7, 2025 at 07:12AM

Show HN: Automate your workflows with screen recordings and AI agents https://bit.ly/4k55h5S

Show HN: Automate your workflows with screen recordings and AI agents Hi all, There are tons of AI agent builders out there. But let’s be honest, for most people, they’re still hard to use. Every single day, I see people struggling to create workflows with these agents and posting their requirements on Upwork. So we built Nutix. Just upload your screen recording and that’s it. Nutix watches what you do, understands your workflow, and builds it with AI agents instantly. You'll have to authorize access to underlying application for agents runs. Access over 2500+ applications and build your automations on top of it. No prompts. No coding. Just show it once , and you're done. https://bit.ly/4lY9rhP May 5, 2025 at 11:02PM

Show HN: A social media network where users share prompts instead of posts https://bit.ly/4k7QwiP

Show HN: A social media network where users share prompts instead of posts Social media these days feels like swimming through a feed of AI generated slop rather than actual human thoughts. Sometimes I wonder what the prompts behind the posts are. I bet there's more creativity going into the prompts than the final content that actually gets shared. What if people just shared their prompts, and the completion was rendered on-demand, client side? Disclaimer: This is a vibe coded proof-of-concept, not a functional service, built in the no-code builder Mocha. It's seeded with a few fake posts. You can create your own posts but they're just saved locally on your own device. To run the completions, you'll need to drop in an OpenAI API key. It uses 4o-mini, so the API calls are super cheap. https://bit.ly/4jYBexf May 4, 2025 at 11:30PM

Show HN: My AI Native Resume https://bit.ly/436GtUf

Show HN: My AI Native Resume I've been deeply involved in working with AI agents and large language models (LLMs) for a while now. During a recent job search, I found myself repeatedly explaining my skills and experiences to various assistants. Around the same time, I was creating content for my website to help hiring teams understand my capabilities better and make informed decisions. MCP had started to gain momentum and I saw a way to reduce my toil. So I built an MCP server that can effectively communicate my qualifications as a job candidate. This server acts as an AI-powered resume, providing an understanding of my professional background and a set of tools, prompts and resources to help explore my skills and experiences. The code is open source, so you can create your own AI-driven resume server. Check it out here: https://bit.ly/3EDKojj . During my job search I paired my mcp server with others such as notion, hirebase, and gmail to build a leads database, write cover letters, and track my job search. https://bit.ly/3EW1kkZ May 5, 2025 at 02:44AM

Show HN: GoVisual – lightweight, zero-config HTTP request visualizer for Go https://bit.ly/4d7Vhqm

Show HN: GoVisual – lightweight, zero-config HTTP request visualizer for Go Hello HN, I kept losing half my debugging sessions to hunting down why a request failed, or which middleware added that header, or why my JSON response was malformed—too many tools, too many context switches. So I built GoVisual, a tiny Go library that wraps your existing http.Handler and gives you a live dashboard at http://localhost:8080/__viz . - Real-time monitoring: Requests show up instantly via SSE - Deep inspection: Headers, request/response bodies, status, timing - Middleware tracing: Visualize execution order and durations - Zero external deps: Pure Go, drop-in middleware; works with standard lib, Gin, Chi, Echo, Fiber It’s strictly for local development—no setup, no config files, just go get and wrap your mux if you pass a -viz flag. I use it every day instead of shoving everything through Postman or hacking logs. It’s MIT-licensed and on GitHub here: https://bit.ly/44XjvBp Would love to hear if this solves a pain for you too, or any ideas on making it even more useful. Thanks! https://bit.ly/44XjvBp May 4, 2025 at 03:55AM

Show HN: I built a tool to automate repetitive tasks by recording my screen https://bit.ly/4dkWBGx

Show HN: I built a tool to automate repetitive tasks by recording my screen Hi HN, I'm excited to share ClickRepeat, a tool I've been building to tackle the tedious, repetitive tasks we all face on our computers. The core idea is simple: you record yourself performing a task once (clicking, typing, navigating apps), and ClickRepeat's AI learns the workflow. Then, you can replay that exact automation anytime, locally or eventually in the cloud. Think of it like creating macros by demonstration, without needing to write scripts or deal with complex RPA setups. For example, you could automate: - Generating weekly reports by pulling data from different apps/sites. - Processing data entry from standard forms or emails. - Running routine UI checks for software development. - Formatting downloaded files consistently. It's designed for anyone – developers, analysts, marketers, support agents, researchers, etc. – who finds themselves doing the same clicks and keystrokes over and over. The goal is to make automation accessible without a steep learning curve. I'd love to hear your feedback, thoughts on the approach, potential use cases you envision, or any questions you might have! Thanks! https://bit.ly/4d7TDoG May 3, 2025 at 09:19PM

Show HN: I made a gamified card collector to celebrate personal achievement(App) Hi HN, Last month me and my friend tried Geocaching, an outdoor activity for your to find treasure boxes. Even though we didn't find the treasure, we both think this is worth celebrating. As a game designer and card game lover, I hoped it would be so cool if I can have achievements recorded as cards, and review them as my collections. So I made an App called Achiva, and now it's available on App Store. There are achievements like: - Sleep for 12 hours - Geocaching (of course) - Build Lego but also serious achievements like: - Becoming a parent - Buying a car - First Job I hope you will like it!

Show HN: OSle – A 510 bytes OS in x86 assembly (sorry about double posting, I forgot to put Show HN in front in the original https://bit.ly/4cYasSJ thread) Hey all, As a follow up to my relatively successful series in x86 Assembly of last year[1], I started making an OS that fits in a boot sector. I am purposefully not doing chain loading or multi-stage to see how much I can squeeze out of 510bytes. It comes with a file system, a shell, and a simple process management. Enough to write non-trivial guest applications, like a text editor and even some games. It's a lot of fun! It comes with an SDK and you can play around with it in the browser to see what it looks like. The aim is, as always, to make Assembly less scary and this time around also OS development.

Show HN: Learn You Galois Fields for Great Good https://bit.ly/4k06ECT

Show HN: Learn You Galois Fields for Great Good Hi All, I've been writing a series on Galois Fields / Finite Fields from a computer programmer's perspective. It's essentially the guide that I wanted when I first learned the subject. I imagine it as a guide that could gently onboard anyone that is interested in the subject. I don't assume too much mathematical background beyond high-school level algebra. However, in some applications (for example: Reed-Solomon), familiarity with Linear Algebra is required. All code is written in a Literate Programming style. Code is written as reference implementations and I try hard to make implementations understandable. Currently I've completed the following sections: 01: Group Theory 02: Field Theory 03: Implementing GF(p) 04: Polynomial Arithmetic 05: Polynomial Fields GF(p^k) 06: Implementing GF(p^k) 07: Implementing Binary Fields GF(2^k) 08: Cyclic Redundancy Check (CRC) 09: Linear Algebra over Fields Future sections are planned: Reed-Solomon Erasure Coding AES (Rijndael) Encryption Rabin Fingerprinting Extended Euclidean Algorithm Log and Invlog Tables Elliptic Curves Bit-matrix Representations of GF(2^k) Cauchy Reed-Solomon XOR Codes Fast Multiplication with FFTs Vectorization Implementation Techniques I hope this series is helpful to people out there. Happy to answer any questions and would love to incorporate feedback. https://bit.ly/4jCkk76 May 1, 2025 at 10:49PM
