Build a tool that publishes coding-session transcripts

Source checkedSoftwareNot specified

Simon Willison used Claude to build a Python utility converting Claude Code sessions into navigable HTML. He publishes source code, example output and development transcripts. Codex handled a separate API reverse-engineering step. No quantified development-time saving is reported.

Source checked: the source link is valid and the automated fact check passed. The summary is AI-assisted. This is not human verification. Check the original source before relying on its claims.

For whom

Independent developers and small teams; Python, CLI and transcript-handling knowledge.

Not for

Not suitable for publishing sessions before checking them for sensitive content.

Still current?

Partly, better ways exist

Today: Publish HTML from local sessions; the tool's web session commands are broken after changes to Claude's undocumented API.

Augments or replaces?

Augments your skills

The developer defines features, chooses dependencies and reviews iterations while AI writes the utility and helps investigate the API.
