onefit.ai

onefit.ai is a specialized Shopify application that leverages advanced computer vision and artificial intelligence to solve the persistent problem of online shoe sizing. Its core value proposition is to dramatically reduce returns and increase conversion rates for e-commerce stores by providing customers with a highly accurate, personalized shoe size recommendation directly on the product page. By simply using their smartphone camera, shoppers can receive a precise fit analysis, bridging the gap between the physical try-on experience and digital shopping.

Key features: The tool allows customers to scan their feet using their phone's camera to generate a precise 3D foot model, measuring length, width, and volume. It then matches these measurements against the brand's specific shoe last data to recommend the optimal size. For merchants, it provides a seamless Shopify integration with a customizable widget, detailed analytics dashboard showing reduction in return rates and increase in average order value, and support for multiple shoe categories from athletic sneakers to formal dress shoes. The system also handles unit conversions and regional sizing charts automatically.

What sets onefit.ai apart from generic size charts or manual questionnaires is its foundation in computer vision, which provides objective, millimeter-accurate data rather than relying on subjective customer self-reporting. Technically, it uses on-device processing for privacy and speed, generating the foot model locally before sending anonymized data to its servers for analysis. Its deep integration with Shopify means no coding is required for store owners, and it works directly within the existing checkout flow. Unlike competitors, it focuses exclusively on footwear, allowing for a more specialized and accurate algorithm.

Ideal for direct-to-consumer shoe brands, large footwear retailers on Shopify, and niche athletic or orthopedic shoe companies looking to scale their online sales confidently. Specific use cases include brands with high return rates due to sizing issues, companies selling premium or hard-to-fit footwear, and merchants targeting international markets with varying size standards. It is particularly valuable for industries where fit is critical to customer satisfaction, such as running shoes, work boots, and fashion heels.

The platform operates on a freemium model. A free starter plan is available for new or low-volume stores to test core functionality, while paid tiers unlock advanced analytics, priority support, and higher scan limits, with pricing scaling based on store order volume and required features.
