infinite canvas · real-time · free to start
Draw anything.
Together.
CoolBoard is the collaborative whiteboard for teams who think visually — sketch, brainstorm, and ship on one infinite canvas.
Your team's creative workspace
Pen, shapes, sticky notes, and live cursors — everything you need to think out loud, together.
Built for visual thinkers
Infinite canvas
Pan, zoom, and draw without boundaries. Your ideas never run out of room.
Real-time sync
See every cursor, stroke, and edit as it happens. Work together like you're in the same room.
