onefit.ai is an AI shoe-sizing app for Shopify footwear retailers. Shoppers use their phone camera to capture their feet; AI turns that input into a personalised size recommendation on the product page. It helps customers choose with confidence, reduce fit-related returns, and improve conversion—without relying on a generic size chart.
We built onefit.ai to solve a frustrating problem in online shoe shopping: not knowing your size.
Returns hurt both customers and retailers – costing time, money, and adding to landfill waste. OneFit.ai uses AI and computer vision to help shoppers find their perfect shoe fit using just their phone, improving conversion and reducing returns.
Early results have been really promising — in one case, 1 in 3 users converted after using our sizing tool.
