siOsi

Free AI color + makeup analysis from one selfie: Skin-Tone Hair, color, undertone & makeup. 12-season type, best hair shade, 15 expert labs. No signup. 9 languages.

siOsi is AI color + makeup analysis from a single selfie โ€” free, instant, no signup.

Color analysis today gives you two bad options: a 5-question quiz that can't actually see you, or a $200โ€“500 in-person session where two analysts often disagree. siOsi reads your actual photo instead.

From one photo you get: - Your 12-season color type (Warm Autumn, Light Summer, Deep Winterโ€ฆ) - Undertone, contrast, and a season-match score - Gold vs silver โ€” which metals actually suit you - Hair-color harmony and recommended shades - A personal palette: the exact colors that flatter you, and the ones to avoid

What no other tool does โ€” 15 makeup diagnostic labs: Upload a makeup look and siOsi grades it like a lab: flash white-cast (why foundation ghosts in photos), oxidation, coverage balance, longevity, crease and transfer risk, and more โ€” plus face, lip, and eyelid shape detection with tailored guidance.

Results in ~60 seconds, in 9 languages, on web and mobile. Free tier with no signup for your first analysis; Pro unlocks unlimited looks and every lab.

Questions & Answers

As answered by people managing siOsi.

  1. What makes siOsi unique?

    siOsi is the only tool that combines full 12-season color analysis with technical makeup diagnostics in one photo-based scan. Most tools do one or the other: a color quiz, or a makeup filter. siOsi reads your actual selfie to give your season, undertone, and palette, then grades your makeup through 15 diagnostic labs (flash white-cast, oxidation, coverage, longevity). Free, instant, no signup, in 9 languages.

  2. Why should a person choose siOsi over its competitors?

    Competing color tools are quizzes that make you self-report answers you don't know, and in-person analysis costs $200โ€“500 with analysts who often disagree. siOsi analyzes the actual photo, for free, with no signup for the first look. It also does something none of them do: diagnoses your real makeup application. You get both halves of "how do I look" in one place.

  3. How would you describe the primary audience of siOsi?

    Primarily women aged 18โ€“35, from complete beginners to working makeup artists, and international (the app runs in 9 languages). It's mobile-first and appeals to anyone into color analysis, makeup, or a glow-up who wants a real answer without paying for a consultant.

  4. What's the story behind siOsi?

    The web is full of "what's my color season?" questions with no good answer: quizzes can't see you, and professional analysis is expensive and gatekept. I wanted to give anyone a real, photo-based answer for free. Then I realized "your colors" is only half the story, so I added makeup diagnostics no other tool offers, grading how your makeup actually performs in photos and real light.

  5. Which are the primary technologies used for building siOsi?

    Next.js 16, React 19, and TypeScript on the frontend; Tailwind CSS with shadcn/ui and Radix; Supabase for auth, database, and storage; Capacitor for native iOS/Android; RevenueCat for subscriptions; Google Gemini and OpenAI vision models plus MediaPipe for face analysis; next-intl for 9-language localization; deployed on Vercel with Cloudflare.

  6. Who are some of the biggest customers of siOsi?

    Individual consumers (B2C); launching publicly August 2026.
