# Watch and replay

See what your agent does on the phone: live while it works, or afterwards, step by step.

## Live

Every phone's start answers two links that open in any browser, with no sign-in: `view` to watch and `control` to use the phone. One viewer holds input at a time, and another can take over. The links work until they expire, after 2 hours by default and a day at most, or until the phone ends.

The picture is H.264 over a WebSocket, with no TURN servers. To show the phone in your own product, [embed it](/content/docs/platform/show/index.html).

## Replay

Every phone is recorded. Within about 15 minutes of its stop, its replay is saved: the screen as a video, beside every tool call with what it did and what it answered. Typed text is left out. A replay is kept 7 days.

- The stop answers the replay's link, `links.replay`, which opens with no sign-in.
- Over REST, `GET /sessions/:id/replay` answers `recording`, `saving` or `ready`, with the video and the calls.
- Revoking a phone's tokens and links stops its replay link too.
