  Prompt Enhancer supercharges every prompt you type into AI chat tools like ChatGPT, Claude, Gemini, and Copilot.
  
  HOW IT WORKS: Click the star button on any AI chat page. The extension reads your prompt, runs a 4-stage enhancement pipeline intent detection, expansion, structuring, and AI polish then rewrites it into a precise, expert-level prompt and inserts the result directly into the text box.
  
  KEY FEATURES:
  - Local AI model (Flan-T5) runs entirely on your device, no server calls
  - 14 smart categories: coding, debugging, research, writing, creative, career & more
  - Prompt quality scorer (0-100) with specific improvement tips
  - Conversation memory across turns
  - LLM-optimized output for ChatGPT, Claude, Gemini, and Llama
  - Supports image and video AI tools: Midjourney, DALL-E, Sora, Runway
  
  PRIVACY FIRST: All AI processing happens locally using WebAssembly. No prompt text is ever transmitted to any server. Google Sign-In is used only for account management.
