Shopify has introduced an AI-powered store builder that allows merchants to set up online storefronts using a single prompt. This tool quickly generates a ready-to-launch store, which users can then customize manually. Alongside this, Shopify has upgraded its AI commerce assistant, Sidekick, with new voice chat and screen-sharing capabilities. The update also includes a new public theme called "Horizon," featuring AI-assisted customization options to simplify store design.
