Whatsit
Snip your screen and ask Claude about it
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).
Hey Product Hunt 👋
I'm a heavy Claude Code / Claude CLI user, and I kept doing the same dance: screenshot something, find the file, paste it into Claude, type "what is this." So I made it one keypress.
Whatsit sits in your tray. Hit Ctrl+Shift+C, snip any part of your screen, and a little popup opens at your cursor to ask Claude about it — a bug, an error, a chart, a UI, whatever. The answer streams back as markdown, right there.
A few things I cared about:
• It uses the Claude CLI you already have logged in — no API keys, no accounts, nothing new to set up.
• It's tiny and native: Tauri + Rust, ~9 MB, no Electron.
• You can drop a snip into an existing Claude session for context.
• Signed in-tray auto-updates, MIT licensed.
Honest heads-up: it's Windows-only for now and requires the Claude CLI, so it's really for people already in that ecosystem.
It's free and open source — I'd love feedback, issues, and ideas: https://github.com/Khaled-BH/wha...
