Google is rolling out the beta of Magic Compose, a new feature in its Messages app that uses AI to suggest text messages based on your conversation. But as Android Police reports, there's a catch: to generate suggestions, Google will send up to "20 previous messages" from your chat to its servers—even if you're using end-to-end encryption (E2EE) with RCS.
Google explains this on its Magic Compose support page, saying it will use these messages, and any emoji, reactions, and URLs they contain, to help its AI create a suitable reply. Google says it won't send any messages with attachments, voice messages, or images, but it warns that "image captions and voice transcriptions may be sent." These messages will then be discarded, with Google not storing any data or using it for training its AI models.
