Meta will soon use conversations with its AI assistant to tailor ads, suggested posts, reels, and Facebook groups. If you ask Meta AI about hiking, the platform may show ads for boots or recommend hiking groups and posts. However, Meta says it will not use AI chats about sensitive topics, including religion, health, politics, or ethnicity. Users cannot turn off personalization from their AI chats, but can adjust ad preferences in settings. One-on-one AI conversations in apps like WhatsApp and Messenger are included, but encrypted chats will remain unchanged, according to the source.
