WhatsApp's built-in AI assistant just got a privacy upgrade. Meta launched Incognito Chat for Meta AI conversations in WhatsApp on May 13, 2026, and it changes how your AI chats are handled in a meaningful way.
What's actually new. When you turn on Incognito Chat before talking to Meta AI, those messages are processed in a Trusted Execution Environment (TEE) — a secure, isolated part of the server that Meta says even its own engineers can't access. The AI chats also disappear by default when the conversation ends, leaving no history stored on Meta's servers.
Why this matters. Normally, when you chat with Meta AI in WhatsApp, those messages don't have the same protections as your regular WhatsApp conversations. Your regular messages to friends and family have always been end-to-end encrypted — Incognito Chat doesn't change that. What it does is bring your Meta AI chats closer to that standard for the first time.
So if you've been hesitant to ask Meta AI about something personal — a health question, a financial worry, something you'd rather not have stored — this mode gives you a more private way to do it.
What it does not do. Even with Incognito Chat on, you're still talking to an AI, and the conversation is still processed by computers to generate a response. "Private from Meta" is not the same as "completely private." It is not the right place for passwords, login details, or sensitive medical records.

How to use it. Look for the incognito option before starting a Meta AI chat in WhatsApp. The exact location in the app may vary depending on your version and region. Meta has also announced a "Side Chat" feature — a separate space for AI conversations — planned for later in 2026.
