Use Claude Code to turn session logs into talk slides

A CS instructor had Claude Code analyze recorded work sessions, then use the results to assemble a slide deck and written summary for a faculty talk.

What they did
Geoffrey Challen had already set up Claude Recorder, which saved his Claude Code activity into a local SQLite database with timestamps, tool calls, and token totals. For a faculty retreat presentation, he asked Claude Code to inspect that database, pull out commit counts and timing patterns, and use the findings to shape the story. It then created a reveal.js deck as a single HTML file, including an interactive timeline, and also transcribed practice recordings with WhisperX before drafting the text summary.
How it went
The analysis covered one 17-hour stretch: 903 prompts, 63 commits, and roughly 16,000 lines added. Claude produced both the slides and the write-up, and no problems were reported with the deck itself.
Tips
This works best when your session history is already stored in a queryable format. If the data may be sensitive, ask the agent to inspect and summarize it without changing anything, and pause before any export or sharing step.

Try it yourself with Claude Code

I have a local database of recorded [work sessions/code sessions] at [path]. First, inspect the schema and tell me what kinds of session data it contains. Then answer these questions: [list the stats, timelines, or comparisons you want]. Use those findings to build a [length]-minute slide deck for [audience] about [topic] as a single [HTML/reveal.js] file. Also draft a short written summary from the session analysis. Do not change the database. Before you export, save, publish, or share anything, show me the planned output and wait for my approval.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
