Discorss is open source, has AI summarization, automatic paywall skips, and can be entirely managed with slash commands. Best of all – self hosting is very cheap and trivial with Railway, so you can add your own customizations to how the RSS bot works. I've been using a personal Discord server as my RSS hub – it's convenient and I can setup different channels for different newsfeeds (i.e. an HN channel for the frontpage).

Show HN: The #1 Reason Your Product Fails – Ignoring User Feedback I’ve spent months researching why solo-built products stall—and time and again it comes down to one culprit: poor feedback collection. Without an easy way to capture, organize, and act on what your users are saying, insights slip through the cracks and your roadmap veers off course. That’s why I built Feedaura, a lightweight widget you drop into your site to: Automatically gather feedback right where users are engaging (no more chasing down emails or scattered notes) Analyze every comment with AI, categorizing sentiment, feature requests, and bug reports on the fly Display it all in a simple dashboard, so you can filter, search, and prioritize in seconds Keep your team in sync, with real-time updates as new feedback rolls in Feedaura makes it effortless for solo developers and indie makers to stay laser-focused on what users really want—so your next release hits the mark.

Show HN: ImgDetect – AI Image Detector to Identify Fake and AI-Generated Images Hi HN community, I recently built an app called *ImgDetect*, an AI-powered tool that detects AI-generated, manipulated, or fake images. How it works: - Upload an image (or paste a link). - ImgDetect analyzes the image using multiple AI models. - It provides a probability score and highlights possible manipulations. Why I built it: With the rise of AI-generated content, it's becoming harder to distinguish real from fake. I wanted to create a lightweight, privacy-focused tool that anyone can use without technical knowledge. Link: - App Store / Download: https://apple.co/44cRd5M... Features: - Fast AI detection - Privacy-focused: No image data is stored - Available on mobile and web I'd love to hear your feedback and suggestions!

Show HN: Remote-Controlled IKEA Deathstar Lamp https://bit.ly/4cTXyoT

Show HN: Remote-Controlled IKEA Deathstar Lamp Repainting the iconic IKEA PS 2014 lamp into the Deathstar from Star Wars has been a popular IKEA hack for quite some time. This variant additionally replaces the manual, rope-operated mechanism to open and close the lamp with a remote-controlled motor. The firmware is based on ESPHome, and its excellent Home Assistant integration enables one to implement higher-level features, like a "sundial" where the aperture of the Deathstar follows the sun elevation throughout the day (see the timelapse video). That said, I will not consider this project as complete until the Imperial March can be played over the stepper motor (just like the legendary Floppotron) ;-) https://bit.ly/42SH2Rn April 27, 2025 at 07:25AM

Show HN: I made no subscription keyword grouping and other SEO tools https://bit.ly/4iDUrmn

Show HN: I made no subscription keyword grouping and other SEO tools I built a keyword grouping tool as a developer managing my own websites' SEO, I found most SEO suites too expensive with only subscription based models, with lots of unnecessary features for my needs. So I made a simple tool for myself that grew into it's own product. Optiwing has tools for Keyword discovery, grouping, content briefing and blogpost drafting with LLMs, SERP checking, and SERP comparison. What I did different: Pay-as-you-go pricing with no subscriptions. A simple integrated workflow from keyword research, to grouping, to content briefing/blog post writing. Large scale keyword grouping is to identify which keywords can be targeted with a single piece of content avoiding keyword cannibilization (multiple pages trying to rank for the same keyword), using live Google search data for accuracy. I'd love feedback, especially from others managing their own SEO and find existing tools too expensive for their needs. Cheers https://bit.ly/3VMbppL April 27, 2025 at 03:51AM

Show HN: Empty Enter Expander – Type less in the terminal with this tool https://bit.ly/42OfhJA

Show HN: Empty Enter Expander – Type less in the terminal with this tool When you have a lot of aliases it can be difficult to remember how was the one you need named especially if you do not use it very often. You can also have files stored in a bin folder and look there to find the name. Another trick is to prepend your commands with a comma then type the comma and hit the Tab key to see only your own commands. There is an article about it somewhere on the Internet. I needed something lightweight to always show me the available commands. Something to run with a few keystrokes. Something that stores commands in files and folder structures. The idea was born at the time of using Linux Debian with the dwm (dynamic window manager). The first version was implemented in bash and it could do three things: start an application, expand text from a template and do a predefined automation on the selected application. It was launched by a keyboard shortcut and opened the list of commands in a new terminal window. The commands were stored in nested folders and it was able to switch between the three modes (launcher, expander, automator). It also required only few keystrokes to do the desired action. For instance, I was in the terminal and hit Ctrl+P. It opened a new terminal and listed applications to launch. I hit the Space to switch to the expander mode. Then I hit the g to enter the Git folder and s for the status. The result was that it put the git status to the terminal I was in before. This expander could be used in any application. It could insert the email template into the browser. Then I migrated to macOS and really missed that tool. So I quickly wrote a zsh vesrion that consists only the expander mode and supports only the terminal. It is activated by hitting Enter on empty command and then it inserts the desired command right into the prompt. For example, when you hit Enter, g and s you will get the git status command to the prompt and you can then execute it with Enter. Of course, those commands and keys are defined by you. There are various and lenghty commands that I use on a daily basis like this and it saves a lot of typing. The tool is called Empty Enter Expander. It is implemented for the zsh as of now.

Show HN: TSCE – Think Before You Speak (Two-Step Contextual Enrichment for LLMs) https://bit.ly/3EqIK4q

Show HN: TSCE – Think Before You Speak (Two-Step Contextual Enrichment for LLMs) Hi HN! I’d like to share TSCE – a Python library that gives small models the ability to follow instructions with above GPT-4-like precision using a two-step architecture. It’s designed for developers who want reliable, high-quality results without the need for fine-tuning large models. TL;DR TSCE uses a two-step approach to improve the reliability of language models. This ensures more accurate and coherent outputs, especially for tasks that require rule adherence or detailed instructions. --- Why You Should Care * No Fine-Tuning: You don't need to fine-tune models. TSCE works with existing models like GPT-3.5 and GPT-4. * Improved Reliability: By decoupling the thinking process (Phase 1) and the answering process (Phase 2), you get more consistent, on-topic results. * Works with OpenAI and Azure: TSCE works out of the box with both OpenAI and Azure OpenAI APIs, so it’s ready to plug into your existing workflows. * Minimal Overhead: The additional latency is small (~2 API calls), but the payoff is huge in terms of clarity and accuracy. Example from tsce import TSCEChat tsce = TSCEChat(model="gpt-3.5-turbo") prompt = "Provide a brief explanation of the benefits of solar energy and how it impacts the environment. Include an example of a renewable energy source other than solar energy." reply = tsce(prompt) print("Answer (Phase 2):", reply.content) # The final response generated after Phase 2 print("Anchor (Phase 1):", reply.anchor) # The structured anchor generated in Phase 1 Output Example: - *Anchor (Phase 1)*: `solar::harvest~light{clean}—echo::sustain[green]` ###END###` - *Answer (Phase 2)*: `"Solar energy offers numerous benefits, particularly in terms of environmental impact. Here are some key points: 1. *Clean Energy Source*: Solar energy is a clean and renewable source of power. It generates electricity without emitting greenhouse gases or pollutants, which helps reduce the overall carbon footprint. 2. *Reduction in Fossil Fuel Dependence*: By harnessing solar energy, we can decrease our reliance on fossil fuels, which are finite and contribute significantly to environmental pollution and climate change. 3. *Sustainable and Renewable*: Solar energy is abundant and inexhaustible. As long as the sun shines, we can harness its power, making it a sustainable energy solution for the long term. 4. *Positive Environmental Impact*: Utilizing solar energy reduces air and water pollution, minimizes habitat destruction, and decreases the strain on natural resources. This contributes to a healthier ecosystem and a more balanced natural environment. *Example of Another Renewable Energy Source*: Wind energy is another excellent example of a renewable energy source. Wind turbines convert the kinetic energy from wind into electrical power. Like solar energy, wind energy is clean, sustainable, and helps reduce greenhouse gas emissions. Wind farms can be established on land or offshore, providing versatile options for generating renewable energy."` --- Installation ``` pip install tsce ``` Customizing System Prompts You can easily customize the system instructions for the final pass by passing in a custom *`final_prefix`*: ``` tsce = TSCEChat(final_prefix="You are a helpful assistant, please respond in 3 sentences.") reply = tsce("Explain the concept of recursion.") print(reply.content) ``` --- If you have any questions or want to try it out, feel free to comment here or head over to the repo. [GitHub Repo]( https://bit.ly/4jqV9UY ) [GDrive: Read the paper, See the proof]( https://bit.ly/3EDZZPG ) Looking forward to hearing what you think! https://bit.ly/4jqV9UY April 25, 2025 at 01:13AM

If you're not familiar with wasi, Compared to something like AWS Lambda, this approach is much more efficient as a single process can serve 1000s of function invocations concurrently and asynchronously, instead requiring an entire VM. This is still early days for the project, but feel free to download the cli utility with cargo install cargo-faasta. Feel free to test deploying functions on my hosted instance at https://bit.ly/4cTNWuq .

Show HN: I made TypeScript's type inference more strict (and smarter) https://bit.ly/4it6xP6

Show HN: I made TypeScript's type inference more strict (and smarter) As a TypeScript developer, I often found myself wishing the type system could do more—*especially when omitting or modifying deeply nested properties* inside complex objects and arrays. For instance, what if I want to remove a deeply nested field like `user.profile.email` and also something like `user.posts[ ].meta.shares` from a type? TypeScript doesn't really provide a built-in way to do that. So I built *DeepStrictTypes* — a utility that lets you *omit deeply nested keys*, even inside arrays, with full type inference and strictness. Here’s an example: ```ts type Example = { user: { id: string; profile: { name: string; age: number; email: string; }; posts: { title: string; content: string; meta: { likes: number; shares: number; }; }[]; }; }; // Remove 'user.profile.email' and 'user.posts[ ].meta.shares' type Omitted = DeepStrictOmit< Example, 'user.profile.email' | 'user.posts[*].meta.shares' >; ``` The resulting type: ```ts { user: { id: string; profile: { name: string; age: number; }; posts: { title: string; content: string; meta: { likes: number; }; }[]; }; } ``` Works great for: - Cleaning up types for API responses - Dynamically transforming deeply nested data - Improving type safety when handling structured JSON [ https://bit.ly/3S6gjM1 ]( https://bit.ly/3S6gjM1 ) Would love your feedback or ideas for improvements! https://bit.ly/3GyfgSz April 22, 2025 at 04:47AM

Show HN: EyesOff – Alerts you when someone peeps at your screen https://bit.ly/42pXkSY

Show HN: EyesOff – Alerts you when someone peeps at your screen Hey HN, this is Yusuf. I've built a privacy focused macOS app which makes use of a locally running neural network (YuNet), to notify you if other people are looking at your screen. YuNet runs fully on-device with no data leaving your computer. The app utilises a 230kb facial detection model, which takes images from your webcam and checks for any faces entering the viewing field of your webcam. If the number of faces exceeds the threshold an alert will be shown. Built with Python + PyQt, the YuNet code comes from OpenCV. Currently it's a macOS app only, however I will be widening access to windows devices soon. Link + Source code: https://bit.ly/4cLFD3O I'd love your feedback on the app, I look forward to reading your comments on thoughts and future directions you'd like to see! https://bit.ly/4cLFD3O April 19, 2025 at 08:44PM

Show HN: I rebuilt my AI browser game using 100 pieces of feedback from HN In February I posted a rough AI browser‑game prototype and asking game dev tips. Then I got about 100 comments that really helped. I went back, rewrote most of it, and here’s the current state: What’s new - Endless world with mountains, lakes, and altitude‑based snow - Living systems – trees grow, bears roam and charge if you trespass - View switch – press V for first‑ or third‑person on the fly - Guest mode – no login, just play - Type‑anything crafting – enter “wooden glider,” “big wall,” “steak,” etc with proper materials; AI invents the recipe and stats Still many things are raw and not-ready, but I want to keep sharing progress and gathering feedbacks. If you try it, I’d love to hear where it falls apart first and whether the core loop feels fun. Thanks for any feedback! https://bit.ly/4jIhD3Q April 18, 2025 at 09:16AM

Show HN: I built an AI-powered packaged food ingredients list vegetarian scanner Hey HN. I have been a vegetarian for the past ten years. At the grocery store, I often find myself manually scanning the ingredient lists on packaged foods, relying on my own knowledge and eyesight to identify non-vegetarian or unfamiliar ingredients that might affect my diet. That's why I built Veri.fy, a go-to vegetarian food scanner powered by Google Vision API and Gemini AI. It helps scan ingredient lists on packaged foods and classifies each ingredient as vegetarian or not. Have a quick look and let me know your thoughts.

Show HN: We made a VS Code extension to recreate a debugger experience from logs https://bit.ly/3YAroIV

Show HN: We made a VS Code extension to recreate a debugger experience from logs A month ago [1], we made an MCP server so Cursor can debug Node.js on its own. We emailed every person that starred our repository [2] and learnt that frontend devs really want to give Cursor access to browser logs, and that backend devs (our intended audience) do not use debuggers nearly as much as we thought. We interviewed friends across startups and discovered that they use logs to debug, because they can’t run services locally on their machine. The services (1) require too much disk, RAM, or CPUs to run locally, (2) have too many service dependencies (think microservices), or (3) are a faff to instantiate locally with a debugger. Instead, our friends instrument their services, deploy them to staging environments via Kubernetes, and then query the logs via data stores (think Grafana, Axiom.co, Google Cloud Logging, etc) or directly (think Kubernetes logs). We thought: "What if we could recreate a debugger-like experience from logs?". That would save them from browsing logs and trying to make sense of them outside the context of the code base. We looked into it and made a VS code extension that lets you (1) import logs, (2) go to the line of code associated with a log, and navigate up/down the probable call stack associated with a log. It's a prototype, but if you're interested in trying it out, we'd love some feedback!

Show HN: I Made Bagel Font https://bit.ly/4414OwV

Show HN: I Made Bagel Font Hey HN, I recently made 3d style Bagel web font (with some more styles) from scratch, and wanted to share the process in case anyone's interested in experimenting or giving feedback. You can play around by typing https://bit.ly/3Rni8nH [Backstory] I was experimenting with Stable Diffusion + ControlNet to generate icons. To my surprise, generating letters this way was actually better than using traditional 3D tools like Blender for this purpose. That led to the idea: what if I could turn into an actual real working font? I found a few tools, but most were either paid or lacked support. So I leaned on Cursor (been using it since launch) and spent a few hours hacking together a Python script using FontTools( https://bit.ly/3EAbkA6 , Opensource font generation python library). Eventually, I got a working .ttf file with an SBIX table (used by Apple’s color fonts)! [Technical details] 1) Create base glyphs Drew black letterforms by hand on iPad (or used open-licensed fonts for other experiments). 2) Add texture/style Used ComfyUI + Stable Diffusion + ControlNet to generate stylized images for each letter. Could also be done in Midjourney, Photoshop, etc. Key part is keeping image sizes consistent. 3) Generate font files Used FontTools (Python). Tried FontForge, BitFontMaker, even paid tools like Glyphs and Fontself — none worked well for image-based fonts. FontTools + SBIX table finally did the trick. [Constraints] SBIX fonts are still relatively heavy, and not all software supports them yet. Photoshop does, but Figma doesn’t (yet). I plan to submit a feature request to Figma once things are more polished. If anyone’s curious to try the font, happy to share it. Would love feedback, ideas, or just to know if this inspires you. I’ve been doing solo creative projects for a while — it can get tough, but knowing it sparks something for someone else helps a lot. Thanks for reading — and feel free to AMA if you're trying something similar! *Updates I'm using a Mac with the Chrome (Arc) browser. It might not work properly on other browsers or OS. If it doesn't work for you, reporting it would really help me improve it next time. Thanks!! https://bit.ly/3Rni8nH April 16, 2025 at 07:39AM

Show HN: Particle - News, Organized https://bit.ly/4cFFVcq

Show HN: Particle - News, Organized Hello HN! Particle News product engineer here. Keeping up with the news is overwhelming in an age of information overload. Particle reimagines the experience by organizing articles into comprehensive "Stories," offering clear, concise summaries to quickly grasp what matters. Today, we reached the #1 spot in "Newspapers & Magazine" on the iOS App Store—and I thought I'd share a bit of our backstory. I've been connected to this team for a long time. About 20 years ago, I shared a house with our CTO and co-founder Marcel Molina. I helped him get started with programming. Since then, Marcel has had an extraordinary career—becoming a senior staff engineer at Twitter, where he helped build foundational features like Retweets, Notifications, and Lists, and later working at Tesla on manufacturing execution systems that scaled across Gigafactories. At Twitter, Marcel worked closely with our CEO and product visionary Sara Beykpour, who led initiatives like Twitter Blue, Twitter Video, and the experimental app twttr . Sara has a background in Software Engineering and Cognitive Science from the University of Waterloo and spent over a decade at Twitter in engineering and leadership roles. In late 2022, Sara and Marcel started prototyping a news app that could reduce the cognitive and emotional burden of staying informed—by using AI to help people understand more, faster. They were soon joined by a few other former Twitter colleagues who helped shape the early concept into a working iOS application. I joined about 15 months ago to contribute across the entire stack. Since then, I've helped design and build major iOS features, rewritten our public website on Cloudflare Workers, and implemented new functionality in our Go backend, which is driven by Google Cloud's Pub/Sub architecture. What Makes Particle News Different Particle helps you navigate the news effortlessly—leveraging AI to help you understand more, faster. Some highlights: • Personalized News – Your feed is tailored to your interests. You can follow specific people, places, and things so you never miss what matters to you. • Clear Summaries – Get a quick overview or dive deeper with detailed, structured context—summarized in natural language. • Perspective Tools – Features like "Opposite Sides" and our political spectrum chart let you explore stories through multiple lenses. • Interactive Q&A – Ask questions about any story and get concise answers with sources and citations. • Audio Summaries – Use the "Play" feature to listen to your feed, specific stories, or even select articles—great for hands-free or on-the-go moments. One of the things we're most proud of is how Particle supports publishers. We've partnered with outlets like Reuters, AFP, and Fortune to host some of their content via APIs. These partners get prominent placement, and their links are highlighted in gold to stand out. This model aims to drive traffic back to publishers and reward high-quality journalism, rather than just aggregating and commodifying it. Transparency is a core value: all sources are cited, generated answers are grounded in evidence, and we take real care to prevent AI hallucinations or misleading summaries. Despite negligible marketing spend, Particle has grown to the top of its category by focusing on engagement with early users and meaningful partnerships with the media ecosystem. Coming soon: weekday mini crosswords—a new feature designed by another longtime friend of ours from 20 years back who went on to work at Twitter, lead development on Firewatch, and release his own games independently. It's incredibly fun and rewarding to be building something meaningful with old and new friends. I feel lucky every day to work alongside some of the best product, design, and engineering minds on a project we hope will help people stay engaged with democracy without burning out. https://apple.co/43QlGWY April 15, 2025 at 10:26PM

Show HN: Real-time AI analysis of Trump's posts on financial markets within 30s https://bit.ly/43V3H1A

Show HN: Real-time AI analysis of Trump's posts on financial markets within 30s Hey HN, I built TrumpPosted to track the potential financial market impact of Donald Trump's social media posts in near real-time. It works by: Scraping his posts almost immediately. Sending the post content + metadata to an AI (Llama 3.3 70b via Groq) for analysis against specific financial subjects (stocks, bonds, crypto, or user-defined like 'Tesla stock'). The AI generates a headline, market sentiment score (0-100), summary, attitude analysis, and detailed commentary. Subscribers get email alerts within ~30 seconds containing this analysis tailored to their chosen subject. All analyses are viewable on the site and browseable via a dynamic archive. Built with Next.js, MongoDB, Groq API (Batch + Single), Apify, and Mailgun. It's purely an informational tool (NOT financial advice – see the disclaimer!) meant to highlight potential volatility triggers and provide AI-driven perspectives. Would love to hear your feedback!

Show HN: AES-256 brute force using structured logic (UUIDs and xy = x/y rule) https://bit.ly/4cz8s3g

Show HN: AES-256 brute force using structured logic (UUIDs and xy = x/y rule) I’ve been experimenting with structured logic as a way to frame search spaces — not in an academic way, just as a personal project. I wanted to know: what happens if you initialize a brute-force run with a simple equality like xy = x / y? Not as a filter, just as a logical ignition point. I used AES-256-CBC encrypted files with UUID passwords and tested against a 1 million UUID space. It cracked it in under 40 seconds. Then I scaled it to a 1 billion UUID range, and it still found the key without issue. This isn’t a crypto tool, and I’m not trying to solve any cryptographic problems. I’m just curious if deterministic logic applied to large search spaces can be useful. Repo’s here if anyone wants to take a look or test it themselves: [ https://bit.ly/3GcbM8s ] Feedback welcome — and open to hearing where this kind of structure-first approach might apply. https://bit.ly/3GcbM8s April 15, 2025 at 01:38AM

Show HN: New Android App alerts you to scams and suspicious links Hello everyone, I’ve developed an Android app designed to help keep you safe from online scams. Here’s what it currently does: 1. Detects scams in messages from unknown numbers in SMS and WhatsApp and alerts you immediately. 2. Scans links shared in conversations and warns you if they are suspicious. If they’re safe, you’ll be notified too—so you can click with confidence. 3. Verifies Instagram ads and flags any that seem suspicious or potentially fraudulent. Privacy first: Your conversations stay entirely on your device. Only links are analyzed externally by trusted servers, and they’re neither stored nor linked to your identity. The app is currently in testing mode, with support for SMS and WhatsApp. I am actively working on expanding to other apps like Instagram messaging, Signal, Discord, Telegram etc. Try it out: https://bit.ly/4llgYHb...

Show HN: Speech and Audio To Text – Transcribe voice messages offline Hi HN, I’d like to share a side project I recently finished: Speech & Audio To Text, a small iOS utility to transcribe voice messages from apps like WhatsApp, Telegram, and Voice Memos — fully offline and without sending any data to the cloud. The motivation was personal. I often receive voice notes when I can't listen to them — during meetings, while commuting on noisy trains, or when I don’t want to disturb others. I used to rely on an app that handled this well, until it moved to a subscription model and started requiring constant internet access. I wanted something that would: - Work offline - Not send audio to any server - Be available with a single, one-time purchase - Support WhatsApp and Telegram voice messages directly - Handle multiple languages So I built it. It’s completely local, lightweight, and doesn't use any AI or external APIs. The speech recognition relies on on-device iOS capabilities, and supports over 60 languages depending on system settings. I'd love to hear your feedback or suggestions. Thanks for checking it out. https://apple.co/42onqUU April 9, 2025 at 07:15AM

Show HN: DrawDB – open-source online database diagram editor (a retro) https://bit.ly/3Ra6rRa

Show HN: DrawDB – open-source online database diagram editor (a retro) One year ago I open-sourced my very first 'real' project and shared it here. I was a college student in my senior year and desperately looking for a job. At the time of sharing it i couldn't even afford a domain and naively let someone buy the one i had my eyes on lol. It's been a hell of a year with this blowing up, me moving to another country, and switching 2 jobs. In a year we somehow managed to hit 26k stars, grow a 1000+ person discord community, and support 37 languages. I couldn't be more grateful for the community that helped this grow, but now i don't know what direction to take this project in. All of this was an accident. But now I feel like I'm missing out on not using this success. I have been thinking of monetization options, but not sure if I wanna go down that route. I like the idea of it being free and available for everyone but also can't help but think of everything that could be done if committed full-time or even had a small team. I keep telling myself(and others) i'll do something if i meet a co-founder, but doubt and fear of blowing this up keeps back. How would you proceed? https://bit.ly/4j30fa1 April 9, 2025 at 01:20AM

Show HN: Browser-Use MCP for Claude that works without an API key Hey everyone, I built an MCP that enables the Claude desktop app to control your browser with Browser Use (YC W25). MCPs (based on the Model Context Protocol by Anthropic) enable Claude to use tools that can do a variety of functions like searching the web, executing code, manipulating files, accessing APIs; basically interacting with things outside the conversation context. The main reason I built this MCP was because I saw that existing Browser Use MCPs required me to get an API key from OpenAI/Anthropic playgrounds in order to use them with the Claude desktop app, which I didn't want to do because I already pay for Claude. It was fun to read the Browser Use code ( https://bit.ly/4lgb75H ) to see how everything works! There's basically an agent (powered by an LLM of your choice) which has access to a bunch of tools. I removed that agent and made the Claude desktop app the agent instead using the Model Context Protocol by Anthropic, and finally gave it access to the Browser Use tools to tie everything together. Hope you find it useful! https://twitter.com/vortex_ape/status/1900953901588729864 April 8, 2025 at 12:38AM

Show HN: A free movies and series randomiser https://bit.ly/4i1Eypi

Show HN: A free movies and series randomiser Hi HN! Over 3 years ago I developed a movies and series randomiser in Cordova web to deploy on app stores. The first versions had ads in it to monetize the development, also a "PRO" version was released for the price of 1 dollar (or something like that, the lowest price tier as far as I remember). Anyway, in recent years I've reached a point where all applications does not need to be monetized, some are just fun to develop and release for free. Show me a Movie is one of them! The current state of the app is the same as of 3 years ago. Besides getting it to work in the browser, minor bug fixes has been fixed. With that said, go ahead and try it out. It is totally free, I only track page count using GoatCounter (for the fun of it). If you want to can leave some valuable feedback and insight which either I or someone else on HN can use in future projects! Warm regards, Lukas https://bit.ly/4cmeCDu April 7, 2025 at 09:00AM

Show HN: Owl, a Spaced Repetition App https://bit.ly/44ape6r

Show HN: Owl, a Spaced Repetition App Owl is built a spaced repetition app. We built it for ourselves mostly because we were unhappy with Anki from a UX perspective, and are now releasing it to everybody else. It is super tiny, but - we think - also pretty good. You can add your own decks manually, or generate them from a PDF (think academic papers, which is how I use that feature) or a prompt. There are no emails except study reminders (when there are cards to study). You can also use our "AI tutor" to review cards conversationally. Looking forward to your feedback! https://bit.ly/42oe1Ni April 3, 2025 at 07:20PM

Show HN: OCR pipeline for ML training (tables, diagrams, math, multilingual) https://bit.ly/42vkSWe

Show HN: OCR pipeline for ML training (tables, diagrams, math, multilingual) Hi HN, I’ve been working on an OCR pipeline specifically optimized for machine learning dataset preparation. It’s designed to process complex academic materials — including math formulas, tables, figures, and multilingual text — and output clean, structured formats like JSON and Markdown. Some features: • Multi-stage OCR combining DocLayout-YOLO, Google Vision, MathPix, and Gemini Pro Vision • Extracts and understands diagrams, tables, LaTeX-style math, and multilingual text (Japanese/Korean/English) • Highly tuned for ML training pipelines, including dataset generation and preprocessing for RAG or fine-tuning tasks Sample outputs and real exam-based examples are included (EJU Biology, UTokyo Math, etc.) Would love to hear any feedback or ideas for improvement.

Show HN: Built a visual UI editor that exports to code I've been specializing in UI for over a decade. Using code for UI is great but I always wished there was a more visual code to build apps and sites. So I went ahead and built it. Decided to build it with Compose Multiplatform since I work a lot with Kotlin. Currently exports to CMP as it was simpler due to the context switch. You can try it for free and export some apps https://bit.ly/3DSaOgQ April 4, 2025 at 11:04AM

Show HN: A new VSCode extension that shows definition functions in a stack https://bit.ly/4lgIRzY

Show HN: A new VSCode extension that shows definition functions in a stack Definition Stack is a new vscode extension I have just released. It is a reading tool for Javascript and Typescript. It is available in the extension marketplace. You just click in a function in any source code, execute a command, and a new tab opens next to the original. That tab has a "block" which contains a copy of the function you clicked in. In that code every word (symbol) that has a definition is highlighted. If you click on a higlighted word a new block opens above the original which contains the source code of the definition for that word. You can click in that block and repeat to create a stack. All function blocks are in the one tab that you can scroll through. There are other options like collapsing a block, deleting it, etc. It is easy to open a block, look at it, and delete it taking you back to the block below. Then clicking in the lower block with another word opens yet another block above. Continuining this process lets you walk the "tree" of references and definitions. This lets you see all the code executed when the original function runs. This is similar to stepping through code with a debugger. The function code is isolated in each block with the name of the original source code file and the lines are numbered the same. But when using the stack you can ignore what file each one came from. This gives a fresh way to look at what all the functions do without the cognitive load of remembering what file the functions are in. AFAIK, this concept is original. Correct me if I'm wrong. My idea came from an IDE for Java from IBM many years ago. In that system there were no source files at all. Each function came from from a database. That IDE was a failure :-) I think my version of that concept will do better because it doesn't replace source files, it just adds a tool for working with source files. The stack is created instantly and is just meant to be used occasionally when it makes sense. It is sort of a Go To Definition on steroids. Please give me feedback. Since it is brand new I want to fix anything wrong including user experience problems. Enjoy ... https://bit.ly/41VK8Vx April 3, 2025 at 11:59PM

Show HN: I vibecoded a 35k LoC recipe app https://bit.ly/4hUdBnp

Show HN: I vibecoded a 35k LoC recipe app Over the last 2-3 weeks, I vibecoded the recipe app that I always wished existed - recipeninja.ai . It now includes a fully interactive voice assistant so you don't need to get your dirty hands over your new iPad when you're cooking. Background: I’m a startup founder turned investor. I taught myself (bad) PHP in 2000, and picked up Ruby on Rails in 2011. I’d guess 2015 was the last time I wrote a line of Ruby professionally. Last month, I decided to use Windsurf to build a Rails 8 API backend and React front-end app, using OpenAI's realtime API for voice-to-voice responses. Over the last few days, I also used Claude Code and Gemini 2.5 Pro for some of the trickier features. 35,000 LoC later, this is what I built! The site uses function-calling to navigate the site in realtime as you chat with the voice assistant, which I think is pretty neat. For the long version, see https://bit.ly/4leIllV... I'd love any feedback you have!
