Meta Platforms announced on Wednesday the rollout of Incognito Chat with Meta AI on WhatsApp and the standalone Meta AI app. The feature enables users to have temporary, private conversations with the AI assistant that are not stored or accessible by the company.

The feature uses “Private Processing technology” in a secure environment, with messages processed so that even Meta cannot access them. Conversations disappear by default when the session ends, setting a new standard for privacy in AI interactions, according to a May 13 Facebook post by Meta CEO Mark Zuckerberg.
“Incognito Chat handles all AI inference in a Trusted Execution Environment that ensures your messages are not accessible to us. The conversations on your phone also disappear when you exit the session. This is different from other disappearing AI products where your conversations logs often remain on other companies’ servers for many months,” Zuckerberg stated, in part.
In layperson’s terms, Incognito Chat creates a one-time, self-destructing conversation thread with Meta’s AI chatbot. Users tap a new icon in a Meta AI chat to start it. The chat exists only on the user’s device during the session, runs in an isolated, secure setup (a Trusted Execution Environment), and disappears upon exit, with no server-side logs kept by Meta.
This differs from standard Meta AI chats or those on other platforms, where conversation history may be stored for improvement, personalization, or training purposes. It is similar to WhatsApp’s existing disappearing messages feature for human-to-human chats, which lets users set timers of 24 hours, 7 days, or 90 days for messages to auto-delete.
The feature is free as it builds on WhatsApp’s standard service, which requires only a phone number and an internet connection, with no subscription fees for core messaging or AI features.
On safety and monitoring against predators, WhatsApp maintains end-to-end encryption for all personal chats by default, meaning only the sender and recipient can read messages. For Incognito AI chats, the private processing adds another layer, with Meta stating it cannot access the content.
The company uses automatic spam detection to block most scam accounts before they reach users and provides tools to report and block contacts. Content involving child exploitation is forbidden, with the company directing user concerns to authorities like the National Center for Missing and Exploited Children.
WhatsApp notes that its design prioritizes known contacts via phone numbers, though group chats can introduce risks if unknown members are added. No specific new predator-monitoring details were announced for the Incognito feature beyond the existing framework.
Messaging apps have experienced explosive growth in recent years. WhatsApp is the world’s most popular mobile messaging app, surpassing three billion monthly active users, according to Backlinko. At the same time, Meta’s combined WhatsApp and Facebook Messenger platforms command over 90% market share in many countries, per Business of Apps.
Ephemeral or disappearing messaging features have gained popularity for privacy, with users rising into the billions across apps. Traditional SMS texting remains widespread, with estimates of over 6 billion texts sent daily and high open rates. Still, internet-based apps have overtaken it in volume for many users, especially internationally and among younger demographics, who send thousands of messages monthly via apps.
In the U.S., 85% of adults use text messaging or apps multiple times per week, with messaging now the leading communication method, according to YouGov.
The rollout begins on Android and iOS for select users and will expand over the coming months, initially text-only with plans for images, voice, and additional capabilities.
WhatsApp has long offered disappearing messages in user chats to reduce digital footprints and storage usage. The new Incognito mode extends similar logic to AI interactions amid growing user demand for privacy with sensitive topics like health or finances.
