Nifty Docs

Look up the word under the cursor in Dash, Zeal or DevDocs, with docsets picked from your language and frameworks.

Maintained. No sign-in. No telemetry. Works in VS Code, Cursor, Windsurf, VSCodium and other editors that use Open VSX.

Features

Right-click useState in a React component, Look Up in Docs, and the React useState page opens in DevDocs

One key to the docs. Put the cursor on useState, os.path.join, Array.from or flex-wrap and press Ctrl+Alt+H (or right-click and choose Look Up in Docs).
Works on every OS.
- Dash on macOS
- Zeal, the free offline docs browser, on Windows and Linux
- DevDocs.io in your browser when neither is installed
The right docsets automatically. The file's language picks the docsets, and frameworks your project uses (from package.json, requirements.txt, pyproject.toml or composer.json) come first. useState in a React project searches the React docs.
Sensible queries. In JavaScript, items.map searches for map; in Python and Go, os.path.join and strings.Split keep their module path.
Search Docs… when you want to look up something that isn't in the file.
Make it yours. Choose docsets per language for Dash/Zeal and DevDocs.
