Hey Product Hunt! 👋

I built PromptVault because I kept writing the same AI prompts from scratch — and so did everyone I talked to.

So I curated a library of 100 battle-tested prompts for real professional work: ⚖️ Legal contract risk analysis 📊 Financial modeling & investor pitches 🎯 Cold email, sales scripts & objection handlers 🔍 SEO briefs, landing pages & email sequences ⬡ System design, code review & API docs 👥 Performance reviews, OKRs & hiring frameworks

15 prompts are completely free — no signup, no credit card, just copy and use.

Pro unlocks all 100 for $29/month. Enterprise adds custom prompts, team seats and API access for $199/month.
