Overview
A prompt store that looks like a gallery.
Prompt Base is a marketplace for AI prompts. Buyers browse by model and category, then buy. Creators get a profile, a way to sell and analytics.
I designed it all on desktop, from home to checkout, selling and settings, plus mobile for key pages.
The challenge
How do you sell a line of text?
- 01A prompt is just text. Buyers must see the result first.
- 02Buyers and sellers need very different tools.
- 03Categories range from Midjourney art to copywriting and DevOps.
The approach
Show the result first, give sellers space.
- 01Example images lead every card and prompt page.
- 02Selling, settings and analytics live in their own account area.
- 03Category chips under search filter the whole marketplace.
Structure
Two sides of one marketplace.
