PromptJectManager - AI Prompt Optimizer

Clean up any AI prompt in the chat box: click to rewrite, or type // to insert your saved ones. Works on ChatGPT, Claude & more.

PromptJectManager helps you turn rough prompts into clear, specific ones, right in the box where you type them. Click into any AI chat field and a small sparkle icon shows up. Press it, and your prompt is rewritten with the detail and structure these models tend to respond to. If you would rather start from something you have used before, type // and pick a saved prompt from your list. What it does: • Rewrites your prompt in one click. Choose a mode for marketing, coding, or writing, or set your own rules. • Builds a full prompt from a one-line idea, with setups for images, video, and step-by-step reasoning. • Scores a prompt from 0 to 100 on clarity, specificity, context, structure, and output, then rewrites it to fix the weak spots. • Keeps a library of your own prompts that you drop in with the // shortcut. • Runs on ChatGPT, Claude, Grok, Gemini, and Perplexity, plus any site you add yourself. You bring your own key. Connect a Google Gemini or OpenRouter key and the extension calls that provider straight from your browser. Your key, your saved prompts, and your history stay on your device. There is no account to create and nothing routes through our servers, so we never see what you write. Looking for prompts to start from? You can browse 750+ original prompts at promptjectmanager.com and add any of them to the extension in one click.
