PromptVault
Auto-save and search every prompt across ChatGPT, Codex,

Our Take
The problem PromptVault solves is one every power user has felt: you write the perfect prompt in ChatGPT, switch to Claude, and it's gone forever. Now you can search every great prompt you've ever written across all your AI tools in one place - that's the move. It's less "auto-save" and more "never lose a good prompt again," which for anyone running serious AI workflows is genuinely useful. Early days, no traction data yet, but the use case is obvious.
