I kept losing my best prompts every time I switched between ChatGPT, Claude, and Gemini. So I built PromptVault.
Save any prompt with one click, then drop it into the chat box on any of the three with one more. Search your whole library instantly. It's the only prompt manager that follows you across all the major AIs — no vendor will ever unify that, so it stays useful no matter which model you're on.
Free: 25 prompts. Pro ($5/mo): unlimited + cross-device sync.
Would love your feedback 🙏
