Tutorials
How to get a specific thing done in this editor, start to finish.
A tutorial here takes one job, such as turning a database schema into an ER diagram or sketching a mind map, and walks through it in this editor from an empty canvas to a file you can use. Each one starts with what the editor cannot do for that job, so you find out in the first minute rather than the twentieth.
They assume a desktop browser and a mouse: the editor has no touch support yet. Nothing needs an account or an install. Boards are saved in your browser, not on a server, so keep an export of anything that matters. That can be a PNG or SVG for a slide or a doc, a diagram file you can import again later, or text where the diagram has a text format, such as Mermaid or DBML.
If you want to know what a notation means rather than how to draw it, start with the guides. If you would rather edit a finished diagram than build one, the templates open one straight in the editor. The keyboard shortcuts page is worth keeping in another tab while you work.
How to make a mind map online
Drop a central idea, branch it out with a click or a drag, and keep it tidy — or paste a Mermaid mindmap and let the editor lay it out. With the gaps named up front.
Turn a DBML schema into an ER diagram
Paste a DBML schema, get an editable ER diagram, edit it, and get DBML back out — with the parser's limits named up front.
