Claude Code already stores full session transcripts locally as JSONL files. Those logs contain everything: prompts, tool calls, thinking blocks, and timestamps.
I built a small CLI tool that converts those logs into an interactive HTML replay.
You can step through the session, jump through the timeline, expand tool calls, and inspect the full conversation.
The output is a single self-contained HTML file — no dependencies. You can email it, host it anywhere, embed it in a blog post, and it works on mobile.

Showing a colleague that flow, and the sequence of not just prompts but the types of Claude outputs to expect, all leading to Claude doing something that would have taken us a half day of work? As a linear video, rather than just a dump or screenshot of a final page? That could help to diffuse best practices rapidly.
OP - you might want to look at the kind of data model Loom used for this problem for videos in general, in terms of workspaces and permissions. Could make a startup out of this!
(Also as a smaller note - you might want to skip over long runs and generations by default, rather than forcing someone into 5x mode! A user of this would want to see messages, to and from Claude, at a standardized rate - not necessarily a sped up version of clock time.)

I’ve mostly been using it for demos and sharing sessions with teammates, but the training / best-practices angle is a great point.
On navigation: you can already step through turns with the arrow keys or jump around the timeline, so you don’t have to sit through long generations. But I agree that smarter defaults (skipping or collapsing long runs) could make it smoother.
And the Loom comparison is interesting — I hadn’t thought about the workspace/permission side yet since this started as a small CLI tool for sharing sessions, but that’s a good direction to think about.

Would this not be visible in a text dump without taking half a day to watch? What's/who's the benefit/benificiary of the realtime experience here?
Granted, I have friends who don't read but prefer visual stimulation. I don't think the overlap with people comfortable with code is very large at all.
