Problem
AI users waste time recreating effective prompts, while prompt creators lack a structured marketplace with content operations and payment infrastructure.
Approach
- Built a marketplace frontend with search, filtering, saving, copying, and premium prompt purchase flows.
- Separated content operations into a dedicated Refine CMS so prompts can be managed without touching production data directly.
- Used Stripe for the freemium model and Supabase for auth, data, and content state.
Outcome
Live prompt marketplace with free and premium content
Separate CMS for prompt publishing and categorization
Search and filtering by AI tool, category, and use case
Solo-built platform, CMS, payments, and content pipeline
