Meta has launched Muse, an AI personal assistant that goes beyond chatbots to execute tasks like sending emails, booking travel, and posting product listings. A key privacy feature: each user gets an isolated Muse Secure VM with no data sharing between agents, and a Sentinel controller approves all external internet access. Meta cannot see passwords or payment data, and end-users control all data access permissions. Premium tiers (USD 20–100/month) available beyond free tier. Rollout begins in the US via iOS, Android, web (muse.ai), and AR glasses coming soon.
