PromptVault — Team Prompt Library with Version History
Why This is an Opportunity
Pure CRUD app with auth, tagging, and a diff viewer. AI agencies are easy to find and already paying for tooling — they'd adopt this instantly.
Key Pain Points
- •Someone on the team tweaked the best-performing prompt and now nobody can find the original version
- •New hires spend their first week asking 'where's the prompt for X?' in Slack
- •Copy-pasting prompts between ChatGPT, Claude, and Midjourney tabs with zero organization
- •No way to know which prompt variation actually produced the best output last month

Original Discovery
AI agencies and content teams keep their best prompts scattered across Notion pages, Slack threads, and random Google Docs. Nobody knows which version of the 'product description prompt' actually works best. PromptVault is a shared prompt library with version history, tagging, and usage notes so teams stop reinventing the wheel every Tuesday.
