Everything you need

Infinite canvas
The full Excalidraw experience — shapes, arrows, freehand, text, and more.
AI text-to-diagram
Describe a flow in plain English — get a Mermaid diagram dropped on the canvas, ready to edit.
Multi-tab workspace
Open multiple canvases at once in tabs — like draw.io. Each tab is its own saved document.
Saved library
Install shapes from libraries.excalidraw.com or import your own. Your library follows you across tabs and reloads.
Sub-second autosave
Every stroke is debounced and persisted within a second — close the tab without thinking about it.
Image persistence
Paste or drop images onto the canvas. They're stored in Supabase Storage and restored on reload.
Export anywhere
Download as PNG or SVG, or copy straight to clipboard. Built into Excalidraw.
One-click Google sign-in
Sign in with Google in a single click, or use email and password — whichever you prefer.
