Stitch Fix has always been known for its personal stylists who curate boxes of clothes for their specific clients. But the company has spent the last year building up its AI infrastructure to help supplement the human element.

On the consumer-facing side, with tools like Stitch Fix Vision, as well as behind-the-scenes tools for its stylists, Stitch Fix has been investing heavily in AI. But at the Glossy E-Commerce Summit in Miami this week, Stitch Fix CEO Matt Baer positioned those AI tools as a supplement, not a replacement, to the humans who pick the clothes.

“We have a lot of AI tools and capabilities in the background that are tools for our stylists, but it’s just as important that we have many ways for clients and stylists to interact directly with each other,” Baer said. “We want our clients to see the nuance beyond what those algorithmic or AI recommendations are serving. The combination is the secret sauce.”

At the summit, Baer showed off Stitch Fix Vision, an AI tool the company launched late last year. It works by generating images of the client wearing different looks that combine algorithmic recommendations with the styling of the human clients. It helps communicate the stylist’s vision of a look for the client without cutting the stylists out.
