Sparkle is a browser extension that replaces English words on web pages with Chinese vocabulary you're learning. Select your HSK proficiency level, and the extension swaps matching words as you read, letting you encounter new vocabulary in context. Hover over any swapped word to see its pinyin reading, English meaning, and hear the pronunciation. All processing happens locally in your browser, so no data leaves your device.
Designed for learners who want to build reading skills without dedicated study time, Sparkle integrates language practice into your everyday browsing. The maker says it was built with Claude Opus and Fable.
