Comment on session replays

Use the Session Comments tab in the replay viewer to discuss a recording, flag a moment, or hand off an investigation. Comments form a flat thread ordered from oldest to newest, with each comment's author, timestamp, and text. To send a replay without adding a comment, share its URL.

Commenting requires the same permission as viewing the replay. Comments support plain text, up to 2,000 characters each.

Add a comment

1. Open a replay and select Session Comments in the side panel.
2. Enter your comment in the text field.
3. To link to a moment, select Add current timestamp, or type a timestamp in brackets, such as [00:10]. Amplitude inserts a clickable badge that seeks the player to that second.
4. To notify a teammate, type @ and choose a name from the typeahead. You can mention multiple people in one comment.
5. Select Post.

Amplitude notifies mentioned teammates through email, in-app, and Slack. You can also mention external users who have permission to view the replay, which sends them an invite.

Edit or delete a comment

You can edit and delete only the comments you post.

• To edit your comment, select the edit action, change the text, then save.
• To delete your comment, select the delete action, then confirm.

Track comment activity

The All Activity tab collects your comment activity across replays. An unread badge marks new activity. Select an item to open its replay and jump to the related comment. Selecting a comment notification opens the replay and highlights the comment.

Comment and replay persistence

Commenting doesn't automatically bookmark the replay. To save a replay for the configured bookmark retention period, follow Bookmark session replays.

Comments persist after the replay's retention window expires. The comment remains, but the replay shows as no longer available.
