No description of https://open-gpt.app/ yet.

siOsi is AI color + makeup analysis from a single selfie — free, instant, no signup. Color analysis today gives you two bad options: a 5-question quiz that can't actually see you, or a $200–500 in-person session where two analysts often disagree. siOsi reads your actual photo instead. From one...

  • No Installation Required
    Being a web application, it can be used directly from a browser without downloading or installing any software.

Possible disadvantages

  • Uncertain Reliability
    Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
  • Data Privacy Concerns
    Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
  • Limited Transparency
    It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
  • Potential Hidden Costs or Ads
    Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
  • Lack of Official Support
    Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.

App Usage

Questions & Answers

As answered by people managing https://open-gpt.app/ and siOsi.

What makes your product unique?

siOsi's answer:

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.

Why should a person choose your product over its competitors?

siOsi's answer:

Competing color tools are quizzes that make you self-report answers you don't know, and in-person analysis costs $200–500 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.

How would you describe the primary audience of your product?

siOsi's answer:

Primarily women aged 18–35, 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.

What's the story behind your product?

siOsi's answer:

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.

Which are the primary technologies used for building your product?

siOsi's answer:

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.

Who are some of the biggest customers of your product?

siOsi's answer:

Individual consumers (B2C); launching publicly August 2026.
