siOsi

siOsi is an AI tool that analyzes makeup photos to give you honest, detailed feedback on how your look works with your skin. Upload a selfie, a celebrity red carpet shot, or even an Instagram screenshot, and the tool examines over a dozen aspects of your makeup: whether the shade actually matches your skin tone, if there's flashback, how well the foundation blends at the jawline, whether the coverage is right, and even if the makeup is symmetrical. The goal is to help you know exactly what's working and what isn't, before you walk out the door — or before you post.

How does it work? You upload a photo directly from your camera roll or take one on the spot. siOsi's AI then runs through 15 separate checks — things like color season, cakiness, dry patches, contour placement, highlighter placement, and whether the makeup will turn orange over time. Each check returns a score and a recommendation, so you get a clear, actionable report. The site also includes a color season quiz (no photo required), makeup tutorials mapped to your undertone, and longform essays on beauty and AI.

The tool is built for anyone who wants objective, data-driven feedback on their makeup. Beauty enthusiasts can find their perfect foundation shade or color season without guessing. Makeup artists can verify their work before a shoot. Influencers can analyze looks they admire to understand exactly what products and techniques were used. siOsi also offers a free month of unlimited analysis, so you can test it out and see your results before committing.
