With enough use, Amazon could gain valuable insights on the ways that people are interacting with AI assistants as the company prepares to overhaul Alexa, the digital assistant it launched more than a decade ago.

Amazon announced Alexa+, a new version of the technology embedded with generative AI, late last month. The company says that Alexa+, which has yet to roll out, is capable of handling more complex tasks and can serve as an "agent" by taking actions for users without their direct involvement.

Andrew Bell, an Amazon e-commerce manager for the National Fire Protection Association who also publishes research on Amazon's patent filings and AI development, came across the new shopping and health features and recently posted about them on LinkedIn.
