Amazon's new shopping assistant chat-bot, “Rufus”, has made it through the test phase and is now available to all U.S. shoppers. According to the article, shoppers have already asked “tens of millions of questions" about topics ranging from product details to recommendations to product updates, and more. 

Rufus can even answer questions about recipes, compare multiple products, create lists of items for a party, etc. 

No information was provided on when Rufus might be rolled out beyond the U.S. market, but at the speed new AI tools are being introduced I can't imagine it will take very long.
