The ones I've used which can convert coding session histories into readable HTML are:
https://github.com/simonw/claude-code-transcripts (only works with Claude Code)
https://github.com/Dicklesworthstone/coding_agent_session_se... (supports many coding agents but the tui feels kind of clunky and it only exports one session at a time)
Sessions are grouped by the folder where you ran Claude Code (e.g. ~/.claude/projects/Users-<user>-<path>), so if you don’t run everything from the same directory, it’s usually easy to narrow down.
They’re also plain JSONL files, so grep works well if you remember part of a prompt.
That said, it might be nice for claude-replay to add a helper command to list or search recent sessions.
But you’re right that sharing in places like Slack could be easier with a video preview. Something to think about.
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.
