Meta announced Incognito Chat, a private mode for Meta AI in WhatsApp and the Meta AI app that processes conversations inside a Trusted Execution Environment — a protected server enclave that even Meta itself cannot access. Conversations are encrypted, not saved to servers, and automatically deleted from devices after the session ends. Meta positions this as the first offering of its kind among major AI labs, contrasting it with competitors that allow chat deletion but still retain server-side logs.

Why it matters

Private-by-default AI chat addresses a major adoption barrier for sensitive use cases (health, finance, legal), and Meta's TEE-based architecture goes further than typical 'don't save history' toggles. Rolling this out via WhatsApp gives it immediate reach to billions of users.

Importance: 3/5
