# Meta Launches Incognito Chat for Meta AI on WhatsApp, Built on Private Processing TEE So Even Meta Cannot Read Conversations

> Meta launched Incognito Chat with Meta AI on WhatsApp, using a Private Processing TEE so messages disappear by default and even Meta cannot read them.

Meta announced Incognito Chat with Meta AI on May 13, rolling out a private conversation mode across WhatsApp and the standalone Meta AI app. Messages disappear by default, are not retained by Meta, and are excluded from AI model training, the company said in its announcement.

The feature is built on Meta's Private Processing technology, which routes prompts through a hardware-isolated Trusted Execution Environment so that Meta's engineers, logging systems, and infrastructure cannot read the conversation during processing. At launch, only text chats are supported — image upload and generation inside Incognito Chat are disabled.

Meta also previewed Sidechat, a related Private Processing-powered feature coming in the next few months that will offer AI help inside any WhatsApp thread without exposing chat context to the company. The launch follows mounting consumer pressure on AI vendors over how prompts are stored and reused for training.
