Your team. Your AI. One whiteboard.

No. Drawdy connects to the AI you already use, such as Claude, ChatGPT, Codex or VS Code, through its MCP server. Your AI reads and draws on your cloud boards while your team works on them, and it runs on your own AI subscription.

Yes, with a coding agent such as Claude Code or Codex. Give it the extension docs: it writes the extension in a public GitHub repository and can add it to your boards as a private extension, which needs no review. Public extensions are reviewed before they appear in the marketplace.

Yes. You can start without an account and keep working without paying: boards on your device are unlimited, and the free plan includes three cloud boards for syncing and sharing. Pro lifts that to unlimited cloud boards and starts with one month free. The free tier itself does not expire.

No. Open Drawdy and the canvas is there — no signup, no email. An account matters once you want a board synced to the cloud or shared with a team.

We love Excalidraw. Drawdy is built for people and AI on one board: your own AI can draw on your cloud boards over MCP on the free plan, where Excalidraw's MCP for saved scenes needs Excalidraw+, and extensions run right on the canvas. The free tier also includes version history and three cloud boards, where Excalidraw keeps cloud storage entirely for its paid Plus tier.

Yes. Drawdy is local-first: boards live on your device, so drawing keeps working with no network at all. Cloud sync is optional, per board.

On your device unless you choose cloud. A board leaves your machine only when you turn on cloud sync for it, which is what lets you reach it from another device or collaborate, or share it as an encrypted snapshot link.

Snapshot links are end-to-end encrypted. The board is encrypted in your browser with AES-GCM, and the key rides in the link's fragment — the part browsers never send to a server. Anyone holding the full link can open the board, so treat it like a password.

Yes. Share a board and everyone edits the same canvas at once, with live cursors. Guests can join from the link without making an account.

Export to SVG, PNG, or Drawdy's open .drawdy JSON format at any time. Your canvases are yours — copy them out whenever you want.

Yes. Select elements in Excalidraw, copy them, and paste straight onto a Drawdy board — shapes, text, and arrows arrive as editable objects. You can also import a saved .excalidraw file from the board menu.

That is the part we build for hardest. Elements are indexed spatially, so selecting, erasing, and hit-testing stay quick no matter how much is on the board rather than getting slower with every shape. History and redraw work off reference-equality diffs, so undo touches only what actually changed, and live cursors are throttled so collaboration never floods the document. Freehand strokes move as a six-number matrix instead of rewriting every point. A single board holds up to 10,000 elements.

Yes. The canvas runs an extension host, and Drawdy's own features ship as extensions too: presentation mode is itself an extension, and the marketplace at drawdy.io/extensions adds more, such as Serene, which plays your drawing back as music, and Pexels Photos and Klipy for stock photos and GIFs. The marketplace's extension API is open for building and sharing your own, so a plugin you write runs on exactly the same footing as ours.
