What is Claude?
Replay converts coding session logs from Claude, Cursor, and Codex into interactive HTML players that work in any web browser. Instead of reading through raw transcripts or static code diffs, you get a video-like interface where you can step through the AI's reasoning and code generation in real time. This is useful for code review, learning how an AI approached a problem, or sharing your development process with colleagues. The tool generates self-contained files that need no server or special setup to view.

Pros & Cons
Advantages
- Makes AI coding sessions much easier to review and understand than raw logs
- No server or authentication needed to view replays; just open the HTML file
- Helps you learn from how AI tools approach problems
- Useful for documenting and sharing your development process
Limitations
- Requires exporting session logs first; not all AI tools make this straightforward
- Limited to the platforms and tools it currently supports
Use Cases
Reviewing an AI-assisted coding session before committing changes
Teaching others how a particular AI tool solved a coding problem
Creating documentation or tutorials based on your AI coding workflow
Debugging: step through exactly what the AI generated and why
Sharing code review feedback that references specific moments in the session
