PromptVault

PromptVault is the universal AI prompt library that works across every major AI platform. Save your best prompts once, find them instantly, and inject them into any AI chat with one click. If you use ChatGPT, Claude, Grok, Gemini or Perplexity, you know the pain — rewriting the same prompts over and over, losing your best ones, starting from scratch every session. PromptVault solves all of that. ✦ PROMPT LIBRARY Save unlimited prompts with titles, full text and tags. Search by keyword or filter by tag instantly. Prompts are sorted by how often you use them so your best ones are always at the top. ✦ ONE-CLICK INJECT Click any saved prompt and it's instantly inserted into the active AI platform input field — works with ChatGPT's textarea, Claude's ProseMirror editor, Grok, Gemini and Perplexity. No copy-paste, no friction. ✦ AI PROMPT OPTIMIZER Paste any prompt and get an AI-improved version — with clearer instructions, better role framing, format specifications and constraint definitions. One click to inject or save the optimised version. ✦ A/B VARIANT GENERATOR Generate 5 style variants of any prompt simultaneously: Concise, Detailed, Role-based, Structured and Chain-of-thought. Compare them side by side and inject the best one directly. ✦ CAPTURE FROM PAGE When you're on a supported AI platform, PromptVault can capture whatever is currently in the input field as a new prompt — so you never lose a great prompt you've already typed. ✦ WORKS ON ChatGPT (chat.openai.com) · Claude (claude.ai) · Grok (grok.com) · Gemini (gemini.google.com) · Perplexity (perplexity.ai) FREE PLAN: Save up to 5 prompts PRO PLAN ($4.99/mo): Unlimited prompts · AI optimizer · A/B variants · Priority support Your prompts are stored locally on your device only.
