siOsi
siOsi is a web-based AI beauty analysis tool focused on skin-tone hair, color, undertone, and makeup diagnostics. It allows users to upload a selfie or any makeup photo—including celebrity red carpet shots, influencer looks, or screenshots from Instagram and Pinterest—and receive an instant analysis of more than 12 aspects of makeup application and color compatibility. The service is offered in 9 languages and requires no signup for its free analysis, with results shown before payment for advanced features. According to the homepage, the AI evaluates color season, foundation shade match, makeup flashback, coverage balance, pore visibility, dry patches and cakiness, product transfer, jawline and neck blending, longevity, oxidation, symmetry, contour and highlighter placement, harsh edges, and creasing. Users receive a scored report with recommendations and confidence scores. The tool is described as tested on a large volume of photos and used by professional beauticians. Beyond photo analysis, siOsi provides color analysis guides, at-home tests, a color season quiz, and a ranking of top beauty influencers. The platform positions itself as a practical diagnostic companion for anyone who wants to know whether their makeup and hair colors truly suit them before going out or buying new products.
