A mind map from the outline you already have.

Write the outline.

Press Write the outline and type one idea a line. The first line is the middle of the map; indent a line (with spaces or a tab) to put it under the line above. Bullets, numbers and Markdown headings are read too, so notes pasted from elsewhere work as they are.

The map is shown as you type. A map holds up to 300 ideas, eight deep; anything past that is left out and the window says how much.

• Open the mind map maker
• A concept map that says how ideas link
• Everything the whiteboard does

Change it like anything drawn.

Branches go out to both sides of the middle in turn, each in a colour of its own, every idea joined to the one it belongs to by a line that holds both. Move an idea and its lines follow; double-click to change its words; add ideas with the tools or by ⌘ or Ctrl and an arrow key.

Templates has a ready mind map too, for when you would rather start drawing.

Save it, share it, present it.

Save the mind map as a PNG or an SVG to put in a document, or as a PDF to print; a PNG or SVG can carry the board inside it, to open and change again. Put a frame round it and Present shows it full screen. Share as a link carries the board locked in the link itself, after the #, which is never sent to any server; anyone who has the link can open it.

On your device, and nowhere else.

Everything is drawn and saved in your browser: nothing is uploaded and there is no account. Turn on Keep this board on this device to find it again when you come back, or save the board as a .excalidraw file to open again here or in Excalidraw.
