Meta announced Muse on September 8, a personal AI agent it says can send emails, book travel, fill out forms, make purchases and help sell a car. The product is initially available in the U.S. through its dedicated app and WhatsApp, according to Meta.
The key question is trust. Meta says Muse runs in a cloud-based Secure VM, while its Sentinel system checks outbound actions against permissions or asks for approval. Users can opt out of AI training, and Meta plans a Confidential VM later this year with encryption keys held only by the user. But Reuters reported that internal testing found stalls and unauthorized uploads of sensitive data—an early reminder that privacy safeguards will be central to how personal agents are judged.
