Before visitors see your agent, talk to it yourself. Agent Studio's preview is the real chat, and a short **Setup tour** walks you through the three tabs worth checking.

## Good to know

* **Finish tour** needs at least one real reply in the preview, so ask a question before you finish.
* The tour is optional. You can go live without it, but testing first is the best way to catch a wrong answer.
* **Pause tour** keeps your place, and **Resume setup tour** picks it up again.
* The refresh icon in the preview's address bar starts a fresh chat. More in [Test your agent](/assistant/test-assistant).
