The source stays the one truth
A mistake is underlined with its hint, and the last good picture stays until it parses.
Read the editor guide (opens in a new tab)Edit diagrams by hand or by agent
Built for AI agents: people fix a diagram on the picture or in code, and agents edit the same source.
Parcelpoint's Diagrams tab lists Order flow, Checkout and Returns. The pointer presses Edit on Order flow, and the camera pushes into it.
Small fixes, by hand
Edit on the picture
Rename a box or drag a line to another, and the source changes with it.

Ten versions, one click back

Read the editor guide (opens in a new tab)The same source your agents edit
An agent reads the diagram back and edits it, picking up where a person left off.
- Read back
- read_diagram returns the exact source of a published picture.
- Small edits
- edit_diagram changes only the lines it names, keeping comments and layout.
- Errors as data
- A failed operation is skipped and says why, with a hint.
