Show HN: Promptflix – an early marketplace prototype for AI image/video prompts

Why I started I use AI tools daily and often spent: $1–3 iterating on a good image prompt $4–6 testing video prompts I noticed many people hit the same issue — spending more on “trying” than on the final result. I wanted to see whether a cost-efficient prompt marketplace could reduce this wasted spend. What’s working now

This prototype includes: Prompt browsing Search + filtering Creator profiles Collections Prompt locking/unlocking Basic analytics for creators Supabase auth + RLS Storage + edge functions React + TypeScript + Tailwind frontend

There are not many curated prompts so far (Midjourney, Flux, DALL·E, Nano Banana, Veo 3, etc.) to test user behavior. About 10 testers are using it so far.

Current limitations Stripe payouts not integrated yet Some UX flows still rough Navigation still improving Still validating how people actually want to buy/sell prompts

This is very much a work in progress.

What I’m looking for Thoughts on the concept of a “cost-efficient prompt marketplace” Feedback on UX and flow Blind spots you see in the approach Any suggestions for measuring prompt originality/value

The prototype is live (linked above).

Happy to answer any questions or share technical details.
