AI Prompt Toolkit
AI Prompt Toolkit gives you 9 prompt engineering tools
AI Prompt Toolkit is a free collection of 9 professional prompt engineering tools that run entirely in your browser → Token Estimator — Project token usage and costs → JSON Schema Generator — Create schemas from sample data → JSON Validator — Validate AI output against schemas → Prompt Formatter — Structure messy prompts → Prompt Cleaner — Remove noise and fix formatting → Prompt Variable Extractor — Extract {placeholders} → Advanced Prompt Optimizer — Polish prompts for clarity
Hey Product Hunt! 👋
I built AI Prompt Toolkit because most prompt engineering tools online require sign-ups or send your data to servers. I wanted something that works instantly and keeps everything private.
All 9 tools run entirely in your browser — zero backend, zero tracking, zero sign-up.
🎯 **Who is this for?** Prompt engineers, AI developers, content creators, and teams building production AI workflows.
💡 **What makes it different?** Everything is in-browser. Your prompts, JSON, and text never leave your device.
I'd love your feedback! What other tools would be useful?

A saved prompt library with version history would be huge, especially the ability to A/B test variations of the same prompt and see which performs better across different models. Right now I find myself copying the same base prompt into the optimizer over and over.
would love to see a side-by-side prompt comparison tool that lets me paste two versions and see the differences in token count, structure, and clarity side by side. would make iterating on prompts way faster
