Boston-based True Fit, an online size-and-fit-personalization platform, has launched "Fit Hub," a generative-AI app that organizes personal size recommendations, product reviews, returns data, size charts and product descriptions on retailers’ sites. The goal is to avoid confusing shoppers by allowing conflicting sizing advice to appear on different product detail pages. True Fit uses a "Fashion Genome" that collects data from 82 million shoppers and 29,000 brands. A "Fit Needs" enhancement lets shoppers identify key areas of garments ("more room in the thigh" or "tops with a longer torso") to fit to specific body proportions.
