# 📚 Idiom Highlighter - Your AI-Powered English Learning Assistant

## 🚀 Transform Any Webpage into an Interactive Language Lab

Idiom Highlighter is a revolutionary browser extension that automatically identifies and explains English idioms on any webpage you visit. With over 100+ built-in idioms and support for custom CSV imports, it turns your daily browsing into an immersive language learning experience. The extension intelligently recognizes not just exact matches but also verb variations (kick/kicked/kicking), ensuring you never miss an idiom in any grammatical form.

## 🤖 Powered by Advanced AI Technology

What sets this extension apart is its seamless integration with ChatGPT. When you click on any highlighted idiom, the AI instantly generates comprehensive insights including clear definitions, contextual usage examples, origin stories when available, and even suggests similar expressions. This transforms passive reading into active learning, helping you understand not just what idioms mean, but how and when to use them naturally in conversation.

## 📖 Smart Context Extraction

Unlike simple highlighters, our intelligent algorithm extracts complete sentences containing idioms by detecting proper punctuation and capitalization. This provides authentic learning contexts, showing you exactly how native speakers use these expressions in real writing. Whether you're reading news articles, academic papers, or casual blog posts, you'll learn idioms in their natural habitat.

## 🗂️ Personalize Your Learning with Custom Databases

The extension supports importing your own idiom collections via CSV files, making it perfect for students working with specific vocabulary lists or teachers creating custom learning materials. The built-in database includes over 100 essential English idioms, from classics like "kick the bucket" to everyday expressions like "piece of cake," giving you a solid foundation for language mastery.

## 🃏 Seamless Anki Integration for Spaced Repetition

Perhaps most powerfully, every idiom you discover can be instantly added to Anki with a single click. The generated cards include the original context, AI explanations, your personal notes, and even the source URL for reference. This creates perfect flashcards for spaced repetition learning, ensuring idioms move from short-term recognition to long-term memory.

## 🎨 Beautiful, Intuitive Interface

The extension features a clean, modern popup with real-time statistics showing how many idioms you've discovered on each page. A three-tab interface organizes information logically: a list view of found idioms, comprehensive settings for customization, and an about section with helpful instructions. The popup adapts to any webpage without disrupting your reading experience.

## 🔒 Privacy-Focused and Secure

All processing happens locally except for AI requests, which require your explicit permission and API key. Your OpenAI key is stored securely in Chrome's encrypted storage and never exposed. The extension respects your privacy while delivering powerful AI capabilities.

## 🌐 Cross-Browser Compatibility

Currently optimized for Chrome-based browsers with planned support for Firefox and Edge, ensuring your language learning companion works wherever you browse.

Whether you're an ESL student aiming for fluency, a teacher creating engaging materials, or a language enthusiast exploring English richness, Idiom Highlighter transforms every webpage into a personalized language classroom. Start your journey to idiom mastery today!
