This browser extension provides an immersive language learning experience by leveraging "comprehensible input" theory, transforming the web into a personalized learning environment. It intelligently replaces words with translations, offering a comprehensive pronunciation learning ecosystem, making it ideal for language learners seeking natural vocabulary acquisition and improved language intuition.

How It Works

The extension employs AI-driven language detection and text processing to analyze webpage content, identifying vocabulary suitable for the user's proficiency level. It offers precise control over translation ratios and context-aware replacement, ensuring translations are appropriate and non-intrusive. A dual-layer learning experience is provided through interactive tooltips that display phonetics, AI definitions, and pronunciation features upon hovering over translated words.
