Amazon pushed its AI ambitions into new territory with a suite of updates that bring its advanced assistant beyond the smart speaker and into browsers, phones, and wearable tech. The company rolled out a redesigned Alexa mobile app that makes the assistant central to the experience and launched Alexa+ in web browsers, letting users chat, upload documents, control calendars and smart devices, and even book tasks. It also revealed progress on Bee, a wearable AI that transcribes conversations and offers insights. These moves signal a fresh push to catch up with popular AI rivals and leverage its huge installed device base.
