PromptVault

👋 Hey Product Hunt! I'm Seth, CTO and creator of PromptVault. **Why I built this:** Six months ago, I realized I was spending 2+ hours per week recreating prompts I'd already perfected. I'd craft the perfect prompt for code reviews, get amazing results, then spend 20 minutes the next week trying to remember exactly how I worded it. I tried everything: - Text files scattered everywhere (no search) - Notion (too slow for quick access) - Apple Notes (zero version control) - Google Keep (limited organization) Nothing worked. As engineers, we'd never code without Git, yet we were managing AI prompts—which are becoming as critical as code—with basically Stone Age tools. So I built PromptVault. **What makes it different:** ⚡ **Sub-100ms search** - Find any prompt instantly, even with 10,000+ in your library. Built from the ground up with advanced indexing and caching. 🤖 **ML auto-categorization** - Stop manually organizing. Our model suggests categories as you type with confidence scores and learns from your corrections. 📚 **Automatic version history** - See exactly what changed, when, and why. Roll back to any version. Just like Git, but for prompts. 🔒 **End-to-end encryption** - We can't read your prompts. Period. Built for teams handling sensitive information. 👥 **Team collaboration** - Share libraries, maintain consistency, control permissions. Everyone uses your best prompts, not just the ones they remember. **Current status:** ✓ Free tier available (genuinely useful, not crippled) ✓ 14-day Pro trial, no credit card required ✓ Sub-100ms search tested on 10,000+ prompt libraries ✓ ML categorization with 85%+ accuracy **What's next:** - Chrome extension for one-click saving -MCP integration into your favorite LLM's - Prompt Community - Advanced analytics - More LLM integrations **I'd love your honest feedback on:** 1. What would make this genuinely useful for YOUR workflow? 2. How do you currently manage your prompts? 3. What pain points am I missing? 4. What price feels fair for the value? I'm here all day answering questions, talking tech stack (Next.js + PostgreSQL with some interesting optimization techniques 🤓), or discussing prompt engineering philosophy. Thanks for checking it out! Excited to hear your thoughts—positive or critical. **Try it free:** https://promptvault.me P.S. - Fellow CTOs/technical leaders: if you're also drowning in hundreds of prompts, I'd especially love to hear your specific pain points!
