How it works
From repo to clickable diagram
Analyze
It reads your repo on your machine: files, imports, calls between parts, services and endpoints.
Claude names the parts
Claude reads a short summary and groups the files into parts with plain names.
Lay it out
Each level is drawn from the facts, with every arrow checked against the code.
Click through it
You get a page you can open box by box, from the big picture down to the files.
Why you can trust the arrows
Every arrow comes from the code
Every box and arrow is traced to the code: imports, calls by function name or URL, database reads and writes, and the services you use. Click an arrow to see the file and line.
Claude only names and groups. It can't add a connection that isn't in the code, and the build rejects a grouping that leaves a file out.
- Imports and calls, by function name or URL
- Database reads and writes
- The services you use

Privacy
Your code stays yours
The analysis runs on your machine. Claude reads a short summary of your repo in your own Claude Code session. The diagram is published as a private Artifact, only when you ask. Usage stats are off unless you say yes, and they never include names, paths or code.
