Amazon’s U.S. customers will soon be able to use Alexa for shopping, to search for products and make purchases through text messages. On Friday Amazon announced the new text feature lets users research and compare products, track deals and price drops and have Alexa complete purchases on their behalf. The feature is rolling out to a small group of invited U.S. customers ahead of a wider launch in the coming weeks. The launch follows Amazon's recent move to block Meta's AI shopping agent, Muse, from accessing its marketplace, saying the tool appeared to access its online store without authorization and saved customer information.
