Everything stays on your computer

The server only counts how often the page is opened and stores nothing about you. Your sketches are saved in this browser on this device and are never uploaded or sent anywhere. They only leave your computer when you export or save a file yourself, or when you start a shared session, which sends the drawing directly to the other participants' browsers.

Clearing this browser's site data removes them, so use Save drawing to file for backups.

Draw together

Peer-to-peer over WebRTC: the drawing travels directly between your browsers. The server only helps them find each other and never sees the drawing.

Let an AI draw with you

Paste the link into Claude Code, Codex or any AI agent that can fetch web pages, with what you want it to do. The link answers with instructions; the AI can then read and edit this drawing through this tab while it stays open.

How drawing together works

You
the drawing, direct and encrypted
Guest
  1. You share a link. It names the room and carries a secret key.
  2. The server introduces the browsers. kritzeln.io only passes their handshake along. The key seals it, so the server can neither read nor change it.
  3. You draw browser to browser. The drawing travels directly and encrypted. It never goes through the server.
  4. A relay only when needed. Behind strict firewalls, and only with your OK, a relay on kritzeln.io forwards the encrypted data without seeing it.
