Field notes
The homepage describes a two-stage system: first build an AST-, import-, and call-graph-based map of the repository, then have agents write documentation against that map. Its public examples span Flyte SDK, FastAPI, and Flask, with the site reporting coverage from roughly 40K to 400K lines of Python. Python is supported now according to the page; JavaScript and TypeScript are described as next.
