Everything on one canvas

One tool for every kind of diagram

Draw freely or drop in structured shapes. It stays fast and friendly whether you are brainstorming or documenting.

Sketchy by design

A hand-drawn aesthetic that keeps diagrams approachable, so people focus on ideas instead of pixel-perfect boxes.

Every diagram type

Flowcharts, mindmaps, UML, org charts, wireframes and free-hand sketches. Native arrowheads and crow's-foot too.

Draw with AI

Describe a diagram in plain words and get an editable draft in seconds. Keep 3 free prompts on any plan.

Diagram from code

Paste Mermaid or D2 and get editable shapes back. Import YAML, Compose and Kubernetes as ready-made maps.

Live collaboration

Draw together in real time with live cursors, presence and point-anchored comments. Share a link and go.

Export anywhere

PNG, SVG and PDF, or copy straight to the clipboard. Turn a drawing back into Mermaid or D2 when you need code.

Think together

A whiteboard your whole team can join

Bring a fuzzy idea to a call, sketch it live, and leave with a diagram everyone understands.

  • Live cursors and presence for everyone in the room
  • Comments pinned to any point on the canvas
  • Version history so nothing gets lost

Teams think out loud with LetDraw

A whiteboard people actually enjoy opening. Here is what a few of them say.

★★★★★

It finally feels like sketching on paper, but everyone can join and nothing gets lost. Our design reviews got twice as fast.

Paste Mermaid, get real shapes I can move around, then export a clean PDF for the docs. It replaced three tools for us.

My students love the hand-drawn look, and the AI prompt gives them a starting point without any fear of the blank canvas.
