The Problem

The Old Way

  • Rewrite the same prompt for different AI models
  • Spend 15+ minutes crafting and re-crafting prompts
  • Get inconsistent, vague, or off-target outputs
  • Jump between tools to test prompts and follow-ups
  • Lose the "good version" across messy chat threads
  • Waste tokens on retries instead of results
The Solution

The Prompt Builder Way

Pick a target model → Generate → Refine → Save/Pin → Run

  • Generate model-optimized prompts for your target LLM
  • Refine fast in a built-in chat workspace
  • Save, pin, and organize prompts in your Library
  • Upgrade existing prompts with the Optimizer
  • Run prompts inside Prompt Builder with Assistant (Grok, Gemini, GPT, DeepSeek, and more)

Rated 5 stars by our customers

Trusted by People Who Ship with AI

From marketers and founders to developers and researchers Prompt Builder helps teams get clearer prompts, better outputs, and faster workflows.

This prompt builder is actually pretty cool. It definitely helps me better articulate when chatting with ChatGPT. I give it 4 stars because I don't think it has the ability to have follow up, meaning, it crafts a great prompt, then if I need follow up, its like a whole new prompt. Worth the lifetime cost as I am sure it will improve.

Prompt Builder is a great prompt refinement tool. I've been using it to boost my productivity and save time on crafting prompts. Sometimes getting the right prompt can be tricky, but that's where Prompt Builder comes in and takes the stress away. Nothing is perfect, but it's a lot better than doing it manually. The tool is still being improved and developed. I think it's really helpful, and remember that these tools are the building blocks and kickstarters for new emerging SaaS.

It is a very useful tool to create easily very detailed prompts customized for each main LLM. It still needs some features and implementations, but being a new product I'm happy that I supported the team with a lifetime plan so that I will receive the new updates!

Prompt Builder has completely transformed the way I create and manage prompts. The workflow is intuitive, smooth, and designed with real usability in mind. What impresses me most is the output quality — the generated prompts consistently outperform anything manually written. It feels like having a creative partner who understands context perfectly and saves hours of work. Highly recommended for anyone serious about getting top-tier AI results.
