One quiet place for the whole journey of a word.
Meet a word on the page, understand it, keep it, rehearse it, and finally teach it — six tools that hand each other the work.
Every word, one tap away.
No more breaking your flow to reach for a dictionary. Difficult words are gently underlined; tap one and its meaning surfaces in place — with a Korean translation when you need it.

Grammar you can touch.
A quiet little game: real sentences from the classics come apart into color-coded word blocks. Wire each word to the port that matches its role — and feel the sentence click back together.

Your reading remembers itself.
Words you look up are saved to your vault; sentences worth keeping become bookmarks. Then the vault does the quiet work — bringing each word back just before you'd forget it.
- Vocabulary lists, bookmarks, and your own saved documents
- Spaced-repetition review on a forgetting-curve schedule
- A speed game that turns review into reflex
- A Reader's Ledger tracking the words you've met and the ones you've mastered
