How to use it

  1. 01

    Draw or generate a structure

    Start from a template, shapes and connectors, indented mind-map text or supported Mermaid flowchart syntax.

  2. 02

    Arrange the canvas

    Move, resize, style, group, align, distribute, layer and connect elements with undoable local edits.

  3. 03

    Save and export

    Store deliberate local projects, copy bounded share hashes, and export clean SVG, PNG, PDF or editable JSON.

Frequently asked questions

Does the board support real-time collaboration?

No. This static local-first edition does not use accounts, WebSockets or a collaboration server.

Is Mermaid support complete?

No. The bounded importer supports common graph and flowchart node-arrow lines and rejects active markup; advanced Mermaid diagrams remain outside scope.

Where are projects stored?

Only projects you explicitly save go to this origin's IndexedDB. Export JSON for a durable and portable backup.

What are the canvas limits?

Projects are capped at 2,000 elements and 10 MiB, with bounded raster export, to protect a static browser tab.
