About
Prompt Master is a Chrome extension that helps you write better AI prompts — in real time, directly inside ChatGPT, Claude, and Gemini. HOW IT WORKS As you type, Prompt Master scores your prompt against the R.C.T.C.F. standard (Role, Context, Task, Constraint, Format) and shows you exactly what's missing. No more guessing why your prompts aren't getting great results. MAGIC WAND Click the wand button next to the send button and Prompt Master rewrites your rough idea into a structured, high-quality prompt — instantly, using the Groq API with your own key. SUPPORTED PLATFORMS — ChatGPT (chatgpt.com) — Claude (claude.ai) — Gemini (gemini.google.com) PRIVACY Your prompts are sent only to the AI provider you configure, using your own API key. Prompt Master has no servers and stores nothing beyond your key and preferences locally in Chrome. SETUP Install the extension Open Settings and paste a free Groq API key (get one at console.groq.com/keys in under 2 minutes) Start typing on any supported platform
