AI Prompt Vault (Working App)

A real working web app (single HTML file, no install, runs offline in any browser) to save, tag, and organize your own AI prompts. Search by text, filter by category, one-click copy to clipboard, favorite your best prompts, and track how often you use each one. Export/import your prompt library as JSON anytime - everything stays on your device. Built for anyone who keeps losing their best ChatGPT/Claude prompts in random notes apps.
