Description by Feiyang Tang(from the App Store)
Echoknot helps you build a personal vocabulary from the words you actually meet.
Save a word as a “knot” with its meaning, sample sentence, translation, context, tags, and grammar notes. Use AI-assisted auto-fill when you want a faster draft, or enter everything manually when you prefer full control.
Echoknot is designed for calm, focused language learning:
• Capture new words quickly • Keep examples, translations, and grammar together • Review your recent vocabulary from the Today screen • Search and filter your personal Wordbook • Understand verb forms, parts of speech, and usage notes • Turn selected knots into short Echo stories for contextual practice • Export your vocabulary anytime • Use the app locally without creating an account
Your vocabulary stays on your device by default. Optional Premium unlocks higher daily AI limits and cloud backup/sync after Sign in with Apple.
Whether you are learning Dutch, French, Swedish, English, or another supported language, Echoknot gives your words a place to return to.
