- 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.
- Arrows that bend your way
- Guides that line things up
- Mind maps from the keyboard

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.
Explore the whiteboardInfographics
Posters, social posts and logos
Switch a tab to Pages and lay out pages: start from a ready-made layout, paint it from your theme, fill it with stats, charts and quotes, then export it print-ready or post it. Or design a logo on an artboard of its own.
Explore infographicsSlide decks
Build the deck, then present it
Start a slide from one of 61 ready-made layouts, or make one from what you drew, then present the deck full screen on your screen alone, your notes behind a button. Slides reference your diagram, so they never drift from it.
- Slide pages, ready-made layouts
- Slides made from what you drew
- Notes only you open
- Your screen, not everyone else’s
Documents
Write it up, diagram and all
Write on pages like a doc, with the diagram right there in the text: pictures that wrap, comments in the margin, and five looks to match your house style. The write-up and the diagram stay one document.
Explore documentsPlans & boards
Plan the work, then watch it move
Switch a tab to Plan and the work moves onto boards of cards: columns with WIP limits, swimlanes, card types with fields of your own, live charts of every card, and dashboards that bring it all onto one page, right beside the diagram that explains it.
Explore plans and boardsSheets
Spreadsheets that sit beside the work
Put a spreadsheet on a Plan tab: real formulas, number formats, sort and filter, live for everyone. Read the cards on the board, or list them as rows that stay linked both ways, and chart any cells in a click.
- Sheets with real formulas
- Cards as rows, linked both ways
- Charts from your cells
- Twelve ready-made spreadsheets
Forms
Collect answers straight into your board or sheet
Build a form where it sits, share one link, and each response lands the moment it is sent: a row in a sheet, or a card on a board ready to work through. No account needed to answer, and nothing else of yours to see.

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 document 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 D1 + 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 document 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. Run your own copy if you prefer, on your own Cloudflare account, in an afternoon.
