Not just another AI prompt library!
I purchased OnlyPrompts on AppSumo about two years ago and wasn’t sure if I was getting just another AI prompt library—especially since OnlyPrompts offers over 150k prompts, which is already impressive!
However, I soon realized this was different because you enter what you think is a “good” prompt, and it enhances it by 10 to 50 fold. You then realize your “good” prompt wasn’t as good as you thought! With Tier 2 and above, you can also set the tone of the prompt, which is a nice feature. The UI is clean, not confusing or cluttered. I doubt I’ll produce 1,500 prompts every month, so the 1,500 prompts/month limit feels very generous. The how-to videos are helpful, and explain the UI and features well.
My only gripe is that their browser extension works only with Chrome. I wish they offered Firefox and Edge extensions as well. Since Chrome, Edge, and Opera all use the Chromium engine, porting to other browsers shouldn’t be too difficult, I think. Overall, whether you’re new to AI or an AI veteran, Prompt Architects will hand-hold you on your quest for optimal AI outputs!

Edited May 14, 2026Hey DanDalal,
"Enhances it by 10 to 50 fold" — that's exactly the transformation we're aiming for. Love that you immediately saw the difference from static prompt libraries. 🙏
Really appreciate you calling out the tone selector, clean UI, and how-to videos. Those details matter, and it's great to know they're landing well.
On the Firefox/Edge request: Totally fair feedback. Chrome extension is live because it covers ~80% of our users, But It's on the roadmap.
Thanks for the killer review and for sticking with us from OnlyPrompts to Prompt Architects. Means a lot!
