Products that do what AICF – a tiny "what changed" feed for AI/RAG (v0.1 minimal core) does
I’m proposing AICF (AI Changefeed) — a minimal, web-native way for sites to expose append-only change events. Instead of crawlers or RAG systems re-embedding everything, they can refresh only the sections that changed. Discovery: a /.well-known/ai-changefeed JSON points to a feed. Feed: an append-only NDJSON file with just 4 required fields (id, action, url, time) plus optional hints (anchor, checksum, note). Goal: cut wasted crawling/embedding while keeping docs/pricing/policy pages fresh for AI/agents. Spec & examples here:…

I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...

I spent a few hours last weekend testing whether AI can replace code by executing directly. Built a contact manager where every HTTP request goes to an LLM with three tools: database (SQLite), webResponse (HTML/JSON/JS), and updateMemory (feedback). No routes, no controllers, no business logic. The AI designs schemas on first request, generates UIs from paths alone, and evolves based on natural language feedback. It works—forms submit, data persists, APIs return JSON—but it's catastrophically slow (30-60s per request), absurdly expensive ($0.05/request), and has zero UI…

At Codeium, we've been building AI-powered extensions for a while (we first launched our VSCode extension with autocomplete a little over 2 years ago!), but we've always thought there would come a day where we would hit the limits of what could be achieved within existing IDEs, so we decided to build our own: Windsurf (yes, it's yet another VSCode fork :) We've stuffed a lot of cool features into Windsurf—a super fast autocomplete model, an inline diff generation experience that feels truly native, but we're most proud of Cascade, which is an evolution of the sidebar chat experience that…

Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…

Hey HN, I built ChangelogHub (https://changeloghub.com) to automate something that is always last on my list for every release: writing clean and human-readable changelogs. Human-readable being the key phrase here. Writing changelogs manually is tedious, especially for backend/infrastructure changes that users never see but matter a lot. I wanted something that didn’t just rephrase commit messages, but actually understood the code diffs. HOW IT WORKS: - Analyzes diffs from PRs or direct commits - Summarizes the changes using OpenAI (code-diffs+custom prompt + heuristics) -…

Hey everyone! Akash and Gabe here from Zenfetch (YC W23) - a chrome extension to help you remember more of what you read. Zenfetch makes it easy to index any content from across the web into a neural search engine and AI chat. Try the chrome extension at https://www.zenfetch.com/?utm_source=hacker_news. How it works: 1. Optionally sync your bookmarks and/or Pocket saves. Zenfetch will continue to sync newly saved items. 2. Click the Zenfetch icon in a tab to save any PDF, YouTube video, note, article, email, forum post, etc. Zenfetch can save almost anything across the…

Hey HN! I've always found it hard to keep up with the latest AI research, so I built Arxiv Feed! https://arxiv-feed.vercel.app/ It's basically a feed of AI research papers + a one-liner explaining what problem its solving, etc. You can also click on any paper to get a TL;DR. Right now, I've only indexed a few hundred large language model papers, but will expand to indexing AI papers in other topics. Thinking of also adding a way for people to up-vote/down-vote papers. Would love to hear any thoughts/feedback! :D Thanks!

Hello everyone! I am Jan, CTO and one of the creators of Pathway, the real-time data processing framework. I’m excited to share Pathway’s ready-to-use AI Pipelines, configurable with just YAML! These frameworks offer out-of-the-box solutions for AI search, RAG, and more—optimized for real-time indexing and in-memory processing. What makes it simple? YAML templates! The pipeline templates are fully customizable using YAMLs to fit your needs, from changing the data sources to the choice of the LLM model, all without touching Pathway’s Python code. Thanks to the Pathway data processing engine,…

The goal was to bring down the cost at the context eng. level. We do it with Layout Memoization. Instead of dumping HTML into the context window, we have built a continual learning browser harness (read only for now). We have built an early prototype for you to try out, where you can: 1. Spins up a browser instance 2. Extract any structured or tabular data from anywhere on the open-web 3. And you can do all this at the cost of a vector search Would love to hear your thoughts on this. Thanks for taking the time to read it.

I built a terminal diff viewer for a workflow I couldn't do comfortably with existing tools: reviewing AI-generated code changes without leaving the terminal session where the agent runs, annotating what needs to change, and feeding those annotations straight back to the agent. Plenty of diff viewers exist, and some can even feed notes back to an agent, but none of them fit that flow for me - they pulled me out of the terminal into a separate app, or the round-trip back to the agent was clunky. Revdiff is how I solved it. From a Claude Code session I type `/revdiff main` or just say…

Hi HN I built a fun little tool: It uses Groq’s LLaMA 3.3 + Puppeteer to analyze a website Then it roasts the design/content/UX with humor And finishes with 3–5 genuinely helpful improvement tips You can try it here: https://ai-roast-vert.vercel.app I wanted to: Practice fast idea-to-launch cycle (built in 2 days) Experiment with a viral-friendly product Monetize with a $0.55 pro version that gives a detailed roast + download Would love your feedback — on the idea, the tone, the usefulness — anything! Thanks in advance

Right now it's a Nicotine patch for brain rot/doom scrolling. You still get the scroll, but with more meaningful content. WHERE I WANT IT TO GO: Users mark what they are interested in (e.g. AI, or Space or Whatever), and it should crawl the latest scientific articles, high quality YouTube videos, pods, present it in a format that fits you, in a nice feed. NOW: You can search for anything (e.g. "Sea Explorers" --> The app crawls Wikipedia or YouTube and pulls together a short feed (e.g. Columbus, Vasco da Gama etc.,). I'm using RAG so that I always can reference the original data source…

I built a tool to roast landing pages with AI agents. I was gathering feedback from watching landing page roast videos, and figured out I could prompt LLMs to analyse a screenshot and roast based on the same criteria. It's not 100% accurate yet, but it has been really insightful when I've tested it on my own websites. Let me know what you think!
