Whatsit

¿Qué es Whatsit?

Whatsit is a tiny Windows tray app for Claude CLI users. Press Ctrl+Shift+C, drag a box around anything on screen, and ask Claude about it — the answer pops up in a compact popup right at your cursor, rendered as markdown. It shells out to the Claude CLI you already have logged in, so there are no API keys or extra setup. Built with Tauri + Rust (~9 MB, no Electron), with an in-tray auto-updater. Free & open source (MIT).
