🔍 WordSense AI: Contextual Meaning Finder Extension

WordSense AI is a lightweight and intelligent Chrome extension that helps users understand the contextual meaning of words across different fields (like Medical, Law, Tech, etc.) with just a text selection. Powered by Google's Gemini AI and built with a simple tooltip-based UI, it delivers instant definitions with field-specific context—directly on the page you're browsing.

🚀 Features

• 🔤 Field-Aware Definitions

  Understand words based on their usage in specific fields like Technology, Medical, Law, and more—no generic answers.

  Just highlight any word on a webpage, and WordSense AI will instantly display its definition via a clean tooltip UI.

• 💬 Gemini AI Integration

  Meanings are generated in real-time using Google Gemini (gemini-1.5-flash) for high-quality, context-rich responses.

• 📋 Lightweight Tooltip UI

  A beautifully styled tooltip appears above your cursor without disrupting your reading experience.

• ⚙️ Extension Toggle & Preferences

  Easily enable or disable the extension, and set your preferred field of interest (stored in Chrome Sync Storage).

🧠 How It Works

1. User selects a word on any webpage.
2. Extension checks if it’s enabled, then fetches the meaning using the selected field.
3. The Chrome content script sends a request to a Flask server.
4. The Flask backend passes the word and field to Gemini AI, which returns a context-specific definition.
