Products that do what Hover – IDE style hover documentation on any webpage does
I thought it would be interesting to have ID style hover docs outside the IDE. Hover is a Chrome extension that gives you IDE style hover tooltips on any webpage: documentation sites, ChatGPT, Claude, etc. How it works: - When a code block comes into view, the extension detects tokens and sends the code to an LLM (via OpenRouter or custom endpoint) - The LLM generates documentation for tokens worth documenting, which gets cached - On hover, the cached documentation is displayed instantly A few things I wanted to get right: - Website permissions are granular and use Chrome's permission…

Gemma Gem is a Chrome extension that loads Google's Gemma 4 (2B) through WebGPU in an offscreen document and gives it tools to interact with any webpage: read content, take screenshots, click elements, type text, scroll, and run JavaScript. You get a small chat overlay on every page. Ask it about the page and it (usually) figures out which tools to call. It has a thinking mode that shows chain-of-thought reasoning as it works. It's a 2B model in a browser. It works for simple page questions and running JavaScript, but multi-step tool chains are unreliable and it sometimes ignores its tools…

Hello, I've created a CSS-library called sunset.css. If offers a collection of (hopefully) useful CSS-powered hover-animations and also some animations that react to clicks instead. It's my first open-source project so I try to make everything right: * I created a npm-project so it is available on npmjs and CDNs * I created a public github-repository with a wiki for documentation * I created a landing page to show off the animations I'd love to here some feedback about all of this! :) Here are the links: https://github.com/philippwilhelm/sunset.css…

just wanted to share this useful tool with you. I have been looking at something like this for a very long time. https://chrome.google.com/webstore/detail/css-used/cdopjfddj... what it does: it analyses your html dom and looks for css classes. Then it extracts it all and combines it into 1 single css file. I used 5 css framworks which was on 340kb kb. This tool made it 36kb!

Hey HN, I recently built a small TypeScript utility called `hover-effects-ts` — it adds fun and experimental hover effects to images using the HTML canvas. You can apply effects like ASCII art, Lego blocks, glitch distortion, and pixelation on hover. The goal was to break away from boring `:hover` transitions and bring some delightful visual feedback to personal websites, landing pages, or error screens — while keeping it lightweight and performance-friendly. Why I built it: I found most image hovers visually bland, and wanted something weird but still dev-friendly. I used canvas to keep the…
