Free tools

Each one does its whole job free. The screenshot tools run in your browser and upload nothing; the explainers answer right here on the page.

Make something

Livestream poster generator: a screenshot of each person on the stream in, a designed going-live poster out.

Pull the text out of any screenshot — right in your browser.

Black out the private parts before you share it. Nothing is uploaded.

Arrows, boxes and labels on any screenshot. Nothing is uploaded.

Paste an error or stack trace. Get the actual cause, in plain English.

Paste an Excel or Google Sheets formula. Learn what it actually does.

Paste a regular expression. Get it decoded piece by piece.

Paste a message. Pick a tone. Get a reply worth sending.

All of these are one gesture in the app: press Ctrl+Shift+O, box the thing on your screen, and ask — no paste, no upload, no switching tabs.
