PromptHub - Share great prompts. Use ones that already work

PromptHub is a marketplace for AI prompts. We spend hours crafting the perfect prompt, get a great result, then it disappears into chat history — never reused, never shared. PromptHub fixes that: post prompts that work, discover ones others have already tested, and stop reinventing what's already solved. Browse by category, save favorites, and build on what the community has proven — instead of starting from a blank prompt every time.

Hey Product Hunt 👋 I built PromptHub because I kept losing my best prompts. I'd spend 20 minutes getting a prompt just right, get a great result — then it would sit buried in a chat log, never reused, never shared with anyone who could benefit from it. PromptHub is a simple fix: a place to post prompts that work and discover ones that others have already tested. No more reinventing the wheel every time you open ChatGPT or Claude. Built with Next.js, Express, MongoDB — deployed and live now. Would love your feedback, especially on what prompt categories you'd want to see most. 🙏
