WhatsApp's AI tools will use a new “Private Processing” system designed to allow cloud access without letting Meta or anyone else see end-to-end encrypted chats. But experts still see risks.

A few weeks after users began noticing that the familiar blue circle for Meta AI was appearing in the messaging app WhatsApp, a new feature is rolling out to keep chats from being used for training by the company's AI features.

WhatsApp has officially introduced a new feature, Advanced Chat Privacy, aimed at giving users greater control over how their messages and media are handled in both private and group chats. Initially leaked earlier this month, the feature has now been made available to all users.
