24 alternatives to Hover – IDE style hover documentation on any webpage

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…

    AI Chrome Extension Builder▲239

    Hey HN, I'm David, one of the creators of Shipper. My brother and I made this tool that builds full-stack software from a few prompts, so it's like talking to ChatGPT. Its purpose is to help you go from idea to product without starting from scratch. There are other no-code builders out there but they either require a technical background or become unreliable for long term projects (e.g. they lose context and break your project). Shipper writes code for you and asks for technical knowledge only if you're comfortable with it. Technical details: I think you could also call it a vibe coding tool…

    Gemma Gem – AI model embedded in a browser – no API keys, no cloud▲156

    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…
