Incognito chats will roll out to WhatsApp and the Meta AI app over the next few months.

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, the company said.

“People are starting to use AI for everything, including some of their most private thoughts, whether that’s tackling financial or health questions, or for advice on how to respond to a tricky message from a friend or a colleague. We think it’s really important to give people the ability to ask these questions as privately as possible,” Alice Newton-Rex, VP of Product at WhatsApp, told TechCrunch over a call.

The company has been laying down the groundwork for secure AI chats on WhatsApp for a while now. Last year, it detailed its private processing infrastructure that would let it build AI features without breaking end-to-end encryption. Since then, WhatsApp has added features like AI-powered summaries of messages that use this architecture.
