What is Hover Extension?

Hover brings IDE-style hover documentation to your browser.
When you're reading code on a documentation site or in an AI chat app like ChatGPT or Claude, you can hover over any token to see documentation — just like you would in VS Code.
HOW IT WORKS When a code block comes into view, Hover detects tokens and generates documentation using an LLM. The docs are cached, so hovering displays them instantly.
FEATURES
- Works on documentation sites, AI chat apps (ChatGPT, Claude), and more
- Granular control over which sites it runs on via Chrome permissions
- Use OpenRouter or configure a custom OpenAI-compatible endpoint
- Supports custom infrastructure (AWS Bedrock, Google AI Studio, etc.)
SETUP
- Click the extension icon and go to Settings
- Add your OpenRouter API key or configure a custom endpoint
- Set which websites the extension runs on
PRIVACY Hover only runs on sites you explicitly allow. Custom endpoint support means you can use your own infrastructure if you don't want code sent to OpenRouter.
