Prompt Vault — AI Prompt Manager

Save, organize, and reuse your best AI prompts across ChatGPT, Claude, Gemini, and more.

Prompt Vault saves the AI prompts that actually worked, so you're not hunting through old chat threads to find that one prompt that gave you good results. Save a prompt three ways: click the floating "Save prompt" button that appears on ChatGPT, Claude, and Gemini; right-click any selected text and choose "Save selection to Prompt Vault"; or add one by hand in the popup or Library. Use a saved prompt without ever leaving the chat. Type "/" as the first character in the chat box, or press Ctrl/Cmd+K, and a search popup opens right there — arrow keys or click to pick a prompt, and it's inserted directly. Prompts with {{variables}} show quick fill-in fields first, so one saved prompt covers many situations. The Library keeps things organized, not just saved: • Prompt Health Check — a rule-based score on whether a prompt sets a role, a format, constraints, and an example • Auto-tag suggestions as you write • Duplicate detection before you save near-identical prompts • Folders, tags, favorites, and full-text search • Version history with one-click restore • View as JSON — turns a prompt into a structured object for tools that want it that way • Usage stats and a 5-star result rating so your best prompts surface naturally • Import/export as JSON for backup Everything is stored locally in your browser. Nothing is sent to a server — Prompt Vault doesn't have one.
