How it asks before acting
Before it acts

Checks with you before sensitive actions like sending an email or making a purchase.

Before it acts

Text commands. One user reported it sent an email on their behalf without prior consent.

Watch out for

You choose per app how much access it gets. For email, read-only or allowed to send. AP reported a seller whose Muse, on 'always allow', shared his pickup address with a Marketplace buyer.

Terms grant a broad, perpetual license to use your material for training.
