Apps stop working
Prompt Builder stopped working two days ago. Very disappointed as it is a good tool. Not sure what is happening.

Severe Limitation
: Severe Limitation
This Product has severe limitations: the prompt can be only 4000 characters, as even simple prompts will easily exceed that limit.
Second, the product is unstable and not fully tested. Most of the times it will error out with Failed to get response OpenRouter API Error 401
Pretty Disappointing product

This tool is just as described - versatile, comprehensive and a definite time saver. Just using it helps me to think of better prompts on my own. Use the Optimizer, and your own good work becomes even better. Newbies and pros all benefit. Thank you!
The prompts aren't generic. They are specific. They suited my purpose. And that was BEFORE I let it optimize my original. I'm grateful and amazed. You've helped me learn. My work will never be AI slop now.
There are excellent and easy to follow guides. They are well worth your time.
Don't miss it if you're a newbie. Don't discount it if you're a pro. Thank you!

Jul 1, 2026Thank you!
The part I love most is what you said about it helping you think of better prompts on your own. That is the real win. The tool sharpens the prompt, but you walk away sharper too, and the Optimizer just takes your good work and makes it better.
Glad the guides are pulling their weight. I spend real time on those because a tool people cannot learn is not much of a tool.

Simple and Necessary Tool
I've been using Prompt Builder before it landed on AppSumo. Part of the reason I was looking for a product like Prompt Builder was because I'm a heavy user of Straico, and my spidey-sense was tingling a couple of months back, thinking that the wheels might fall off pretty soon.
I needed a simple prompt library that I could count on, and Prompt Builder definitely does that, and it does it well. But what really surprised me was the optimizer.
I didn't buy it for the optimizer, and I didn't think I would use it, but as it turns out, I've taken many of my existing prompts I had in the Straico platform, ran them through the optimizer, and ended up with much, much better prompts.
When I touched base with the founder shortly after purchasing Prompt Builder to request the ability to bulk export my prompts from Prompt Builder, he put it in place really quickly, and it does exactly what I requested it to do. Now I have much more confidence in loading Prompt Builder full of my most important prompts, knowing I have a very simple bulk export feature in case anything happens in the future.
I'd like to see more sharing features, but for my use case this is a simple product that does exactly what I need, and it does it well. If you want to try it, you should definitely check out the optimizer.

Jul 1, 2026Really appreciate this one. Coming over from Straico and wanting a prompt library you can actually count on is exactly who I built this for, so I'm glad it's holding up.
Funny how often the Optimizer is the surprise. People buy it for the library and stay for what it does to prompts they already had.
On more sharing: shareable prompt links and team workspaces are both on the roadmap, so there is...
