WhatsApp has launched Incognito Chat with Meta AI which is a completely private way to interact with AI. Incognito Chat conversations are processed in a secure environment that even Meta cannot see, and disappear by default.
This is not simply a privacy label slapped onto an existing feature. The architecture behind it is fundamentally different from standard AI chat interactions. Incognito Chat is protected with Private Processing, which means that Meta genuinely cannot access it. As Mark Zuckerberg described it — Incognito Chat handles all AI inference in a Trusted Execution Environment that ensures your messages are not accessible to the company.
How WhatsApp Incognito Mode Works in Practice
Users can start an incognito session by tapping on a new icon in one-on-one chats with Meta AI. The feature will also be available on the standalone Meta AI app.
Once you enter the incognito session the privacy protections activate immediately and comprehensively. Meta said these incognito conversations are not saved, and messages will disappear by default once you close the chat. The session will also end if you close the app or lock your phone, and Meta AI will lose the context of that particular conversation.
Even Your Web Searches Stay Private
This detail is particularly impressive and goes further than most people would expect. Even web searches made during the incognito conversation are protected. Meta AI asks search engines to find up-to-date results using search terms based on your chat, without linking those searches back to you.
The privacy is not just within the chat window. It extends to every piece of activity the conversation generates.
What You Can and Cannot Do in Incognito Mode
Users will only be able to type in questions and get text responses — they will not be able to upload or generate images. They will also have to confirm their age because Meta does not allow users under 13 on its platforms.
The text-only limitation is a reasonable trade-off for the level of privacy protection being offered, and for the sensitive personal questions this feature is primarily designed to handle, text responses are almost always what people need anyway.
