- LiveReal-Time CollaborationShare a link and build together, cursors and edits in sync.
Collaborate
Work on it together, live
Share a link and your team is on the canvas with you: live cursors, comments on any element, actions handed to teammates, and Workshop, a mode for running a workshop, with timers, votes and a spotlight on the thing you mean.
Explore collaborationDiagrams
Diagrams that look designed, not dragged
Shapes that snap into line, arrows that follow them, and icons, tables and components when boxes are not enough. Start from a template, recolour it with a theme, or describe it to your AI and let it build the diagram for you.

Whiteboard
A whiteboard that feels like paper
Switch a tab to Draw and the canvas becomes a whiteboard: three markers in hand, a pen that answers to pressure, and erasers that take a whole stroke or just a smudge. Sketch it rough, and let it snap to shape when you want it neat.

Your data, your call
We don’t make money by being creepy. No third-party trackers, no ads, no resale, no surprise audience. Just a diagram editor that treats your work like your work.
Your data is yours
Every canvas lives in your own row, scoped to your owner id. Export any tab to PNG, SVG, PDF, Mermaid, Markdown, or portable JSON whenever you like, and delete your account from settings to remove it all in one go. We don't make money by holding it hostage.
Never sold, never traded
We don't sell your data. We don't trade it. We don't share it with advertisers or model trainers or anyone else. There is no paid tier and no plan to add one, so we have no commercial pressure to monetise what you draw.
Encrypted at rest and in transit
All persistence runs on Cloudflare Durable Objects and R2, which encrypt every row and blob at rest with AES-256. Every request is TLS, end to end. The same protections protect telemetry, share links, and uploaded images.
Private by default
A new canvas is visible only to you until you generate a share link. Share links are unguessable codes you choose to hand out: protect them with a password, set them to expire automatically after a week, a month, or six months, or revoke them at any time, instantly disconnecting anyone currently using one.
Open source, auditable
The whole stack (editor, API, this site) is on GitHub under the MIT license. Anything we claim here, you can read in the source.
