Meta launches Incognito Chat for Meta AI on WhatsApp
Meta is rolling out an "Incognito Chat" mode for Meta AI on WhatsApp and the Meta AI app that enables fully private, ephemeral conversations processed via Meta’s Private Processing technology. According to Meta, Private Processing uses Trusted Execution Environments (TEEs) within a secure cloud setup so user prompts are handled without Meta or WhatsApp being able to access chat contents. Incognito Chat is temporary by default and will be complemented by side‑chats that let users query the AI alongside regular conversations without exposing the main chat. Meta positions the feature as a privacy-first foundation for AI capabilities such as message summarization and writing suggestions. The company says Meta AI already serves over one billion monthly active users and is supported by the Muse Spark model, which now includes voice conversation features.

Meta launches Incognito private AI chats on WhatsApp
Meta is introducing an "Incognito" chat mode for Meta AI on WhatsApp and in the Meta-AI app that uses its Private Processing technology to keep conversations fully private, including from Meta itself. According to Meta, Private Processing runs user AI requests inside a server setup based on Trusted Execution Environments (TEEs) in a secure cloud so chat contents are not accessible or stored by default. The Incognito chats are ephemeral by default and Meta will also add private inline side‑chats that let users query the AI inside existing conversations without exposing those queries. Meta publishes a technical whitepaper on Private Processing and plans a global rollout of Incognito chats in the coming months. Meta AI is supported by the Muse Spark model and the company says the assistant has over one billion monthly active users.
WhatsApp adds incognito mode to Meta AI chats
Meta is adding an "incognito" conversation mode for its Meta AI chatbot inside WhatsApp and the standalone Meta AI app. Incognito sessions run in a secure private-processing environment, are not saved, and messages disappear by default when a user closes the chat, the app, or locks their phone — which also causes the AI to lose that conversation's context. Users can start an incognito session via a new icon in one-on-one Meta AI chats. The feature will roll out to WhatsApp and the Meta AI app over the next few months. Meta said the incognito chats use its recently released Muse Spark model. The company is also developing a private-invocation feature called "Side Chat."
WhatsApp Adds Incognito Mode for Meta AI
Meta announced an incognito chat mode for Meta AI inside WhatsApp that creates private, temporary conversation rooms processed via a "Private-Processing" secure environment. Users will enable the mode by tapping a dashed-line chat bubble in the Meta AI chat; in incognito mode Meta says conversations are not stored and cannot be read by the company. Meta plans a rollout to all WhatsApp users in the coming months and intends to add private side-chats that let users ask private questions without disturbing the main chat. The company published a technical whitepaper on Private Processing and invited feedback from the security and research communities.
