Overview
- Meta announced Wednesday it is launching Incognito Chat on WhatsApp and the Meta AI app, with a gradual rollout over the coming months.
- Requests run inside Private Processing Trusted Execution Environments that Meta says even it cannot access, a design the company says has been reviewed by outside security firms.
- Conversations are not saved, and messages disappear by default when a session ends or when the app closes or the phone locks.
- At launch the mode is text‑only, and Meta plans a Side Chat option to privately invoke the bot inside ongoing WhatsApp threads.
- Meta says the assistant will refuse harmful prompts, yet advocates warn private, vanishing chats could hinder detection of self‑harm or illegal activity, a concern surfacing after Meta removed Instagram’s optional encrypted DMs.
