# ReadFlow: Smart Contextual Translation Extension
## Tagline
1. Stay immersed while reading foreign news, articles, and research papers.
2. Context-aware AI delivers seamless explanations instead of word-by-word translations.
3. Only translate the words you actually need help with.

## Overview
ReadFlow is a Chrome extension that transforms how you read foreign language content by leveraging advanced linguistic analysis and AI translation. Built on a robust backend that uses Zipf's law to identify unfamiliar words based on your reading level, this extension provides precise, context-aware translations with phonetic pronunciation guides and detailed explanations—without cluttering your screen with unnecessary translations.

## Core Features
### 1. Level-Adaptive Smart Translation
- Personalized Vocabulary Filtering : Uses Zipf's frequency analysis to automatically detect words above your selected reading level (Beginner A1 to Advanced C1).
- Relevant Only : Translates only the words you’re likely unfamiliar with, preserving the flow of the original text.
- Dynamic Adjustment : Adjust your reading level anytime to receive translations tailored to your growing proficiency.
### 2. Accurate Language Detection
- Browser Integration : Utilizes your browser’s detected page language to avoid misidentification (e.g., fixing cases where "Appendix B Full Benchmark Results" was previously mislabeled as German).
- Fallback Auto-Detection : Automatically identifies language if browser detection is unavailable, ensuring seamless operation across all content.
### 3. Rich Word Annotations
- Phonetic Pronunciation (IPA) : Learn correct pronunciation with International Phonetic Alphabet guides.
- Concise Definitions : Get quick, context-aware brief definitions for instant understanding.
- Detailed Explanations : Access in-depth word usage and context for deeper learning.
### 4. Multi-Language Support
- Bidirectional Translation : Seamlessly translates between English and target languages (e.g., Chinese, Japanese) based on your browser’s language settings.
- Structured Output : Preserves original page formatting and HTML structure, ensuring translations integrate naturally with the content.
### 5. Efficient Performance
- Smart Caching : Stores translation results to reduce API calls and speed up subsequent page loads.
- Lightweight Processing : Optimized backend processing minimizes impact on browser performance.
## How It Works
1. Page Analysis : The extension processes the current page, extracting text while preserving HTML structure.
2. Language Confirmation : Uses your browser’s detected page language (or auto-detects if unavailable) to ensure accurate processing.
3. Vocabulary Filtering : Applies Zipf’s law to identify words above your selected reading level.
4. AI Translation : Generates translations with IPA, brief definitions, and detailed explanations for filtered words.
5. Inline Annotation : Displays translations as hoverable annotations directly on the page.
## Use Cases
- Language Learners : Focus on expanding vocabulary at your current proficiency level without overwhelming translations.
- Academic Researchers : Quickly understand technical terms in foreign language papers without interrupting your reading flow.
- Professional Readers : Navigate international content (reports, articles, documentation) with targeted translations of industry-specific terms.
- Casual Browsers : Enjoy foreign language blogs, news, and social media with contextually relevant translations.
## Technical Highlights
- Robust Backend : Built on a scalable translation service with error handling and fallback mechanisms.
- CEFR Level Alignment : Aligns with Common European Framework of Reference for Languages (CEFR) levels for standardized proficiency targeting.
- API Optimization : Uses efficient token usage to minimize translation costs and response times.
- Extensible Architecture : Supports future language additions and feature enhancements.
## Why ReadFlow Stands Out
Unlike generic translation extensions that translate every word (cluttering your screen and slowing comprehension), ReadFlow uses linguistic science to deliver only the translations you need. Its accurate language detection fixes common misidentification issues, and its rich annotations provide a comprehensive learning experience—making it the ideal tool for anyone looking to read confidently in foreign languages.
