SizeSane

SizeSane is a mobile + web AI app that recommends the most likely best size for a specific product, not just a brand. Users answer a short fit quiz (height, weight range, typical fit preference, known good items), optionally add one quick body scan using the phone camera, and then paste a product URL or search inside the app. SizeSane pulls the item’s size chart, fabric composition, stretch notes, and review text, then predicts size and expected fit (tight/true/relaxed) with a confidence score. It also flags “high return risk” items when sizing signals conflict (inconsistent reviews, missing measurements, vanity sizing patterns). The goal is fewer returns and fewer “order two sizes” purchases. Realistically, it won’t be perfect—so it shows uncertainty and suggests when to size up/down only when evidence is strong.
