What can Instinct do?
Early users describe it negotiating bills, booking appointments, chasing cancellations and coordinating vendors. Reports also describe a multi-day outage in September and aggressive automated booking attempts that led one service to ban an account.
03 · Privacy
Privacy and which to choose
Agents that act in your accounts need more trust than a chatbot.
Is Meta Muse safe for my private data?
Be cautious. Muse trains on interactions by default, and a columnist reported it synced his iMessages after he declined access. Meta disputes that report, saying Muse reads Messages only after a user enables both Full Disk Access and the Messages connector.

Does Instinct use my data for training?
By default, yes, with an opt-out. Disconnecting an app does not delete data Instinct already copied unless you request deletion.
Meta Muse vs Instinct: which should I pick?
Muse if you are an adult in the US or Canada and want a free public app with per-action approvals; Instinct only if you have an invite and accept a young company's beta. For either, connect the minimum accounts and require approval for payments.
