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installing it locally, and restarting your environment (e.g., Claude Desktop) just to try it out feels clunky and outdated.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

Show HN: YapCards (iOS) – Voice-driven flashcards with AI feedback Testflight Link: https://apple.co/43huXoW I wanted to be able to practice Spanish vocab while on my commute to work so I created YapCards. It's an iOS app focused on making flashcard studying hands-free & efficient. Like Anki, but entirely spoken. You choose a list to practice, the app reads the prompt out loud (e.g. "What charge does a proton have?"), & you respond by voice. YapCards uses AI to evaluate your response & provide feedback. 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. Thoughts around voice recognition / silence detection, reducing latency, and improving AI feedback greatly appreciated! Thanks for taking a look. May 15, 2025 at 02:14AM

Show HN: I built a simple AI-powered ATS for small teams https://bit.ly/4jWFOMk

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. Would love feedback from anyone who’s struggled with hiring at a small company or has thoughts on the approach. https://bit.ly/4dkByUv May 14, 2025 at 10:11AM

Show HN: LLM-God – An LLM Multiprompting App https://bit.ly/3ZeZ3bv

Show HN: LLM-God – An LLM Multiprompting App I’ve been building and maintaining LLM-God, a desktop LLM prompting app for Windows, built with Electron. It allows you to ask one question to multiple LLM web interfaces at once and see all the returned answers in one place. As a very big user of AI tools in my daily life, I hated having to click through multiple tabs in my browser, and slowly copy paste a single query into multiple LLM web interfaces. This inspired me to find a better way, which resulted in this app. I tried to make it as minimalistic as possible while still being functional. Key features: • Starts with a default of Perplexity, ChatGPT, and Gemini, with the option to add more LLM's like Grok, Claude, and DeepSeek. • Responsive, keyboard-friendly 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

Show HN: GS-Base – A multifunctional database tool with Python integration A wide range of possible use: from simple contact/inventory lists, photo albums to editing CSV/text files and processing (transforming, splitting, merging, normalizing) large, multi-GB data tables in various file formats. Text, Numeric, Long Text / Memo fields, Image / File fields; Code fields for code snippets with syntax highlighting for 16 programming languages. You can analyze, query and consolidate data, generate pivot tables, perform calculations, merges and joins with up to 256 million rows, 16K columns and 4GB+ files efficiently using even older PC's. Several filtering methods, searching for duplicates, for unique values and their frequencies, search-as-you-type, random and quartile searches, full-text searches, fuzzy searches. RegEx filtering of millions of records in seconds regardless of the number of the returned found records. Searching for file duplicates, finding similar photos/images, music and video files using any EXIF tags and multimedia (e.g. mp3/mp4) tags. Playing filtered lists of mp3's. Very fast data consolidation - you don't have to bother with permanent indices; internal indexes are created automatically whenever aggregation and binary lookup functions need them. Generating disk/folder listings and monitoring all file changes with searchable history of modifications. Mass-renaming, -copying and -deleting files based on filtered file listings. GS-Base can be installed on any portable storage device and used without performing any registry modifications. Fully offline - doesn't need internet connection. To move it to another computer you can simply copy the installation folder containing a few files. Questions and suggestions are welcome. https://bit.ly/43tJQpq May 12, 2025 at 10:02PM

Show HN: Piny – Astro, React and Next Visual Editor for VSCode, Cursor, Windsurf https://bit.ly/4jTd0UU

Show HN: Piny – Astro, React and Next Visual Editor for VSCode, Cursor, Windsurf Hi, Matjaz here. Piny is a visual editor that runs directly in Visual Studio Code, Cursor and Windsurf. It supports Tailwind CSS, Astro, React and Next.js. All edits happen directly in the code, so there are no abstractions, no cloud services and no lock-in. 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
