Promptimize AI

Promptimize AI is a browser extension that acts like 'Grammarly for prompt building,' turning rough prompts into refined, high-quality inputs with a single click across ChatGPT, Claude, Gemini, and other major AI platforms. It's aimed at anyone who works in AI chat tools daily -- marketers, developers, and content creators -- who want more consistent, professional outputs without manually engineering prompts. Its main differentiator is that it lives directly inside the AI platforms you already use, adding saved prompt libraries, reusable custom variables, and side-by-side model output comparison rather than being a separate standalone app.
