PromptVault Pro is a privacy-first, offline-capable AI prompt management tool built entirely in vanilla HTML, CSS, and JavaScript — no frameworks, no servers, no API keys, no subscriptions.
It solves a real problem every AI power-user faces: prompt chaos. Your best prompts are scattered across Notion, text files, browser bookmarks, and your memory. And every time you use one, you're manually copy-pasting and replacing [Product Name] [Audience] [Tone] over and over again.
PromptVault Pro fixes this with a Dynamic Variable Engine — write your prompt template once with [Variables], and the app generates input fields for each one automatically. Fill them in, get a live preview, copy in one click.
| Feature | Description |
|---|---|
| ⚡ Dynamic Variables | Write [Variables] in templates. Auto-generates input fields per variable |
| 📋 1-Click Copy | Copy the filled, final prompt to clipboard instantly |
| 🏷️ Tags & Filtering | Organize prompts by tags. Filter your library in one click |
| ⭐ Favorites | Pin your most-used prompts to always sit at the top |
| 💾 Export / Import | Download vault as .json backup. Restore on any device, any browser |
| 🔍 Instant Search | Real-time search across all prompt titles and content |
| 🌙 100% Offline | Works without internet. Double-click and use |
| 🔒 Zero Tracking | No servers, no analytics, no data collection. Ever |
