The problem
Design a product where thousands of prompts stay findable and stay manageable.
Working with AI models runs into the same wall every time: you write each prompt again from nothing, with no way to build on what already worked. Prompterly flips that around — find a proven prompt, copy it, adapt it. Our job was to design a marketplace where a huge library stays navigable and the quality of every item is out in the open.
The approach
Catalog and search
Built a catalog of 1,000+ prompts with search by keyword, model, and use case. You find the right prompt in seconds instead of scrolling for it.
Nine categories
Split the library into nine areas — from Copywriting and Coding to Image, Video, and Music. Navigation runs from the job to the prompt.
The prompt card
Designed a card with a community rating, a verified-quality mark, and one-tap copy. The score and the copy button are right there.
The short path
Cut the interface down to one flow: find, copy, use. Nobody has to stay on the platform longer than they need to.
Five models
Brought ChatGPT, Claude, Gemini, Midjourney, and FLUX under one library, with free access and a paid tier.
Business impact
A repeat job no longer starts with an empty field: you pick a proven prompt from the catalog and use it right away.
Before the project
Every AI prompt was written from scratch, with no shared library of what worked and no honest read on quality.
Entry point
Search by job, model, and category.
Where it broke down
Time went into phrasing and retries, and prompts that had already proven themselves were hard to find and reuse.

The result
The marketplace runs at prompterly.org: 1,000+ prompts across five models, reachable through one search and nine categories. The catalog keeps growing, and the card with its rating and quality check keeps the standard of the content visible. Next up: a larger library and customization tools.
