Meta launches on-device AI scam detection feature for WhatsApp

·43 views

Meta is rolling out an optional Scam Alert feature on WhatsApp that uses on-device machine learning to identify suspicious messages. The tool is currently available in a limited beta and displays a private warning to the user when a message is flagged as a potential scam. Users can then choose to block or report the sender, or continue the conversation if they believe the alert is a false positive. The feature builds on Meta's earlier scam detection tool for WhatsApp device-linking requests introduced this year. All analysis is performed on the device, meaning message content is not shared with Meta.

Under normal conditions the dislike button sits beside the like button, so relocating it would require extra steps to reach. The change would likely reduce how often viewers use the dislike option.
