Why Stackline
A directory built for actually deciding, not just browsing
Every listing is reviewed by a person before it goes live - no bots scraping app stores and dumping the results into a category. If it's on Stackline, someone checked that it works as described.
Features
A directory built for actually deciding, not just browsing
Every prompt's variables — tone, audience, topic — show up as editable fields before you copy. No more pasting a prompt and manually hunting for the placeholder text to swap out.
Built for the Community
The directory gets better because people use it
Fill in the name, category, and pricing — no lengthy application. A reviewer checks it before it goes live, usually within a few days.
