Meta is introducing an option for WhatsApp users to have private chats with its AI assistant that not even the company can read. It's pitching Incognito Chat with Meta AI as a way to have clandestine conversations with the chatbot under the protection of end-to-end encryption, which WhatsApp has long offered for chats between humans. Meta revealed it was working on such a feature at its LlamaCon generative AI conference in April 2025. The company built Incognito Chat with Meta AI using its Private Processing tech . It said that messages exchanged with the chatbot in this mode are handled in a secure environment that no one else has access to. The messages are not saved and they disappear by default.

The company says its new Incognito Chat allows you to use its AI chatbot without anyone else--including Meta--being able to access your conversations. WhatsApp said on Wednesday it is launching an AI chat function known as Incognito Chat that is built to allow users to converse privately with Meta AI --such that Meta itself cannot access the questions or answers. The feature is based on WhatsApp's Private Processing scheme, which debuted a year ago and already underlies WhatsApp's existing AI features, including message summarization and composition tools. The idea of Incognito Chat is to create a way for WhatsApp to offer AI chat integration that does not conflict with the communication platform's commitment to end-to-end encryption, the privacy scheme in which only direct participants in a conversation can read messages or hear a call. Most generative AI platforms now offer some type of "incognito mode," but these features are usually designed to separate users from the questions they ask and the answers they receive rather than including a mechanism to entirely shield those questions and answers from the provider's view.
