Instead of flashcards you forget, it helps you collect words you actually encounter — with real context, sentence examples, and grammar analysis — so you build knowledge that sticks. **Capture Words Instantly** Add Korean words and their meanings by typing or speaking. Voice input with live transcription lets you capture spoken Korean hands-free, so you can practice pronunciation as you learn. **Save from Anywhere with Share** Reading a Korean article in Chrome?
