isketch vs Excalidraw
Different tools for different jobs. Here is where Excalidraw is the better choice, and where isketch adds something it does not.
Where Excalidraw is better
- A wonderful drawing surface: the fastest free-hand sketching of any tool here, with a library of community shapes.
- Live collaboration and a share link out of the box, no server of your own to think about.
- A big audience: the hand-drawn look people already recognise from engineering blogs.
Where isketch adds something different
isketch is a sketchpad whose output is agent-ready: the diagram is text a coding agent reads exactly, and can edit back.
- The diagram is also text: every sketch is a `.flow` file an agent reads exactly (names, kinds, directions) instead of a canvas of shapes to guess from.
- Copy for AI turns it into a brief a coding agent can build from, and the MCP server lets the agent update the diagram as the code changes.
- Files diff line by line, so pull requests can show what changed in the design.
