Guided code walkthroughs · heuristic · offline

Turn code into a guided walkthrough.

Paste one or more files. codetour finds the landmarks—functions, classes, imports, sections—and lays out an ordered tour. You reorder the stops, write a note for each, and export the whole thing as Markdown or a standalone page. No accounts, no network, no AI.

Paste your code

Split multiple files with a // file: path/name.ext marker on its own line (or # file: for Python). One file is fine too.

Everything stays on this device.

Paste some code above and press Build the tour. codetour will read the structure and propose an ordered set of stops—entry points first—that you can reorder, annotate, and export. Or press Load a sample to see it work.
