AI Whiteboard

Think messy.
Ship tidy.

An endless canvas for the half-formed part of the work. Sketch, stick, and argue in real time, then turn the whole thing into a structured diagram with one click.

One click

The sketch was already the diagram.

Brainstorming and documenting are usually two tools and one retyping session. Here they are the same canvas, and the tidy version is a toggle away.

SignupVerify emailPick a planFirst project

Loose sticky notes and freehand arrows. Nothing is locked to a grid yet.

The toolbar

Everything a marker could do, and then some.

Freehand that feels like ink

Pressure-sensitive strokes with real pen sizes, colors, and opacity. It looks hand-drawn because it is.

Shapes when you want them

Rectangles, circles, diamonds, arrows, and lines that snap to grid, align, and distribute cleanly.

Text anywhere

Labels, headings, and annotations dropped straight onto the canvas with real formatting.

Images, GIFs, stickers

Drag a screenshot in and resize, rotate, and layer it with everything else on the board.

Genuinely infinite

Pan and zoom forever. The board never runs out of room mid-thought.

Theo on the canvas

Ask for a diagram, ask what the board says, or ask for the version that makes sense to a stranger.

Everyone at once

The room, without the room.

Live cursors carry names, so you can see who is drawing what while they draw it. Share a link and a reviewer can open the board without making an account.

Questions

Whiteboard questions, answered.

What is the OpenCharts whiteboard?
An infinite freehand canvas with a hand-drawn look. Sketch, drop shapes, add text, and pull in images and GIFs. Theo can generate content on the canvas, explain what is already there, or turn a sketch into a structured flowchart.
Can I turn a sketch into a flowchart?
Yes, and it is one click. Switch a board between whiteboard and flowchart mode without losing anything: your sketches and shapes are preserved, and Theo helps convert loose boxes and arrows into properly structured nodes and connections.
Is the whiteboard free?
Yes. It is included in every plan, including the free one. AI assistance, real-time collaboration, and export are all included with no card required.
Can several people draw at the same time?
Yes. Multiple people can draw, place shapes, and annotate the same board simultaneously, with live named cursors and presence indicators so you always know who is doing what.
How do I share a board with someone outside my team?
Share a link. Viewers can open the board without creating an account, which makes it practical for a client review or a quick sanity check from someone in another company.
What can I export?
PNG for a quick paste, SVG when it needs to stay sharp at any size, and PDF for sending on. The board can also be converted to a flowchart first, which unlocks the wider set of diagram export formats.
