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? Try it free:

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

Maker

 Thanks so much for the suggestion! I really liked your idea, so I went ahead and built a Prompt Comparison tool. You can now compare two prompts side by side, including differences in structure and other key details. If you have a moment, I'd love for you to check it out and let me know what you think. Your feedback really helped improve the product. 😊

 can you help me to get better

Love that everything runs in the browser, no signup, no friction. The Variable Extractor alone is going to save me a ton of time when refactoring my prompt libraries.

 Thank you so much for your kind words! I'm really glad you found the browser-based approach and the Variable Extractor useful. My goal is to keep the toolkit fast, simple, and privacy-friendly. I'm working on more improvements based on feedback like yours. Thanks again for your support!

I never planned to build an AI platform.

I was just a guy working a 14-hour job, earning around ₹15,000 a month, trying to change my life through YouTube. I couldn't afford expensive AI subscriptions, cameras, or premium prompt libraries. Every time I searched for prompts, I found websites that gave me one or two useful prompts, then asked me to pay, flooded me with ads, or pushed products before helping me solve my problem.

The biggest challenge wasn't using AI—it was knowing how to talk to AI. My prompts were weak, and the results were disappointing.

So I decided to build a small prompt website just for myself.

I didn't know much about coding. I failed 32 times before I finally managed to build a working version. At first, it was only meant to solve my own workflow, but then I realized there are thousands of people just like me—students, creators, freelancers, and people with limited budgets—who simply want AI to work without paying for everything.

That's why I created AI World Hub.

Instead of locking basic features behind a paywall, I wanted the core experience to stay free. Today, I've built multiple prompt tools that help people write better prompts, save time, and get better AI results. I'm still improving the platform every week based on feedback.

I'm not building this to become another company selling expensive AI tools. I'm building it because I know what it's like to have big dreams and almost no resources.

So if you try AI World Hub, I'd love your honest feedback. Even one suggestion can help me make it better for the next person.

Thanks for being part of this journey. ❤️
