True Fit Fit Intelligence Platform
AI fit and sizing platform for apparel and footwear retailers, with recommendations across ecommerce pages and shopping agents.

True Fit uses shopper profiles, product data, and purchase-and-return outcomes to recommend sizes and explain fit, feel, stretch, structure, and related questions. Retailers can deploy it on product pages, listings, search, homepages, Shopify, APIs, or AI agents through MCP.
It is used by apparel and footwear brands, marketplaces, Shopify merchants, ecommerce teams, and developers. The platform does not publish a dedicated public pricing table; Shopify billing is based on order volume, and broader packages require contacting True Fit.
