About

Add readable timestamps to ChatGPT messages, switch between 12-hour and 24-hour formats, and optionally sync the visible timeline.

- Show timestamps beside ChatGPT messages.
- Choose 12-hour or 24-hour time.
- Timestamp all messages or user messages only.
- Explicitly sync visible messages and timestamps when wanted.

Timestamps display locally without sending content. Choosing Sync current timeline sends visible prompt and response text to ChatStamp. Common identifiers are redacted before storage. ChatStamp does not sell data or use it for advertising.
