Every stroke, on every screen — the exact same second.

Sketchy is a plain whiteboard that syncs itself. Draw a stroke and it lands on every screen in the room the moment you lift your pen. No refresh. No merge. No conference call.

the three-stroke rule

A room is three things,
drawn in order

01

Pick up a tool

Pencil, rectangle, circle — a handful of honest shapes. That's the whole palette, on purpose.

02

Sketch on the same plane

You draw on a canvas that isn't yours. It's the room's. Coordinates, not layers — everyone's strokes live in the same place.

03

Everyone watching, instantly

A stroke is as seen by the room, sent, and painted on every other screen. The latency is a blink of an eye.

Built like the
tool it replaces

A whiteboard has one job: let everyone think out loud in front of each other. Sketchy does that and refuses to get in the way.

A canvas you don't own

There's no 'my board'. A room is a shared plane — anyone in it can draw, and everyone sees the same page.

Real-time, genuinely

WebSocket under the hood. Shapes broadcast the moment they're drawn, so a pen stroke reads like it's happening now — because it is.

Boards that remember

Shapes persist with the room. Close the tab, come back tomorrow, and the sketch is still there waiting for you.

Rooms behind a sign-in

A room is only as open as you want it to be. Sign in, pick a room, and the door stays locked to the list.

the board is open

Make the first stroke.
The room will follow.

Create an account, open a room, and hand the link to whoever draws with you. That's the whole tutorial.
