Prompt Builder

Generate, optimize, test, and manage AI prompts in one place

Visit

Prompt Builder is a prompt engineering workspace for writing, testing, and saving prompts. Describe the task in plain English, and it helps you create a prompt that matches the model you choose. Start with a draft, refine it in chat, save or pin versions, then run them when you are ready. It works with GPT, Claude, Gemini, Llama, Mistral, DeepSeek, Grok, Perplexity, and more. You also get an Optimizer, an assistant for quick tests, and a library of reusable prompts and templates from the community.

Use Cases

Any case when you using AI for your workflow. Pick the model you're using and Prompt Builder adapts the prompt structure and output format to match. You get better results with fewer retries.

I build Prompt Builder to make my prompts for AI perfectly structured every single time. It saved me a ton of hours and bring my workflow productivity to the higher level.

Is there a way to try it out on some user defined data? Like having a fixed dataset and comparing the performance before and after optimizations?

The model-specific optimization is a smart approach. Different LLMs respond very differently to prompt structures, so having that built-in saves a lot of trial and error. The prompt library feature is also useful for teams who need consistency across projects.

Great tool. I recommend it

I think the idea its generic, why i use this app and no the same ia like gemini o gpt ?

Model-specific prompt optimization is a big win - most people underestimate how differently GPT, Claude or Gemini respond to the same structure. The optimizer + versioning combo sounds especially useful for teams running AI-heavy workflows. Love that it reduces retries — that’s the real productivity gain

Clever tool. a lot of people don't understand the importance of prompt quality and are surprised if they get poor AI output

Very good idea! Good luck with startup
