The agent

Bring your own model, with hard limits you set

A side panel that can read the page you are on, click things, run scripts, and work across tabs. You supply the model provider. Keys live in Keychain. Every run is recorded locally, and every limit is a number you choose.

If you do not want any of it, one switch in Settings hides the panel, its shortcut, AI Search, and every other AI affordance in the app. Nothing is deleted.

Choose your provider in Settings, Agent. This capture uses the on-device Apple Intelligence option; other providers have their own model and credential requirements.

Things to try

about 12 minutes

Worth filming

Set the turn limit to two and let a run hit it on camera. The limits being real is more interesting than the answer.
