Overview
- Meta, which announced the feature Wednesday, has begun a gradual rollout in WhatsApp and the Meta AI app, with early availability in Argentina and wider access expected over the coming months.
- In this mode, conversations are end-to-end encrypted and processed inside a Trusted Execution Environment, a sealed computing area that Meta says keeps even its own systems from seeing the text.
- Sessions are temporary and text-only, with messages not stored on servers and set to disappear by default, and image-generation tools are not yet available in Incognito.
- Meta also previewed a protected side chat that will let people invoke the assistant privately inside existing threads, with desktop support for Windows and macOS to follow.
- Reporters noted that fully private AI chats could remove records that have aided investigations, and coverage contrasted Meta’s promise here with Instagram DMs losing end-to-end encryption and with rivals like Snap that retain AI chat data.
