Fit Check is built around two main components: a website (hosted on Vercel) and a Chrome extension, both connected to a Supabase backend. Users sign up on the website and complete a style survey. That data is stored in Supabase and used by the Chrome extension (only available if the user is logged in) to:
- Evaluate if a product fits their preferences,
- Prompt for reviews after purchases,
- Pass reviews into a Sentiment Analysis Model, which feeds into an LLM Engine connected to a product/shop database for smart recommendations.
All user data and review history are stored in Supabase, keeping everything in sync and personalized.
