Most AI chatbots offer some version of a privacy mode, but there’s usually a catch: the company can still see what you’re asking. Meta says WhatsApp Incognito Chat is different.
The feature launched today on WhatsApp and the standalone Meta AI app. You start a session by tapping a new icon inside a one-on-one Meta AI chat. From there, your conversation runs inside a Trusted Execution Environment, a secure, isolated setup on Meta’s servers where the AI processes your messages without the contents being visible to the company.
The chat disappears when you close the app or lock your phone, and Meta AI loses all context from that session when it ends. For now, WhatsApp Incognito Chat is text-only, so you can’t upload images during a private session.
What actually makes this different from other privacy modes
The underlying technology is WhatsApp’s Private Processing system, which Meta first detailed last year and has already been running quietly under features like AI-powered message summaries. Rather than retaining conversation context server-side between messages, your device sends that context fresh with each new request. So there’s nothing to log, and nothing to subpoena, at least in theory.
Meta also uses anonymous routing to separate your account identity from the requests being processed. Will Cathcart, Meta’s head of WhatsApp, put the thinking plainly: people ask AI about health issues, finances, and career decisions, and it shouldn’t feel like that information automatically belongs to the company running the AI. Incognito Chat also has safety guardrails built in, refusing harmful queries or cutting off a session entirely if needed.
Meta plans to follow this up with Side Chat, a related feature arriving later this year that will let you get private AI help within any existing WhatsApp conversation without interrupting it. The broader Meta AI expansion on WhatsApp has been rolling out steadily, and this is the most privacy-forward piece of it yet. WhatsApp Incognito Chat is rolling out gradually over the coming months on both Android and iOS.
