Japanese from zero to the real thing, one guided path
Each sentence in the Core course has exactly one new word and only grammar you have already seen, so it is always understandable, never a wall.
78 short plain-English lessons appear inside your study session the moment the next sentences use them, and you can read ahead any time.
Each card returns just before you would forget it, so reviews take minutes and not hours.
On Netflix, YouTube and Prime Video, every subtitle word is marked by how well you know it, with furigana only on the words you do not know yet.

Turn your notes into flashcards that stick
Upload PDFs, PowerPoint or Keynote slides, Word and Pages documents, images, or lecture audio and get flashcards built from exactly your source content.
Review intervals grow as you remember a card and shrink when you forget, with hard cards flagged as critical so you can fix them.
Generate full quizzes and timed mock exams from your material, alongside oral exam practice that scores what you actually said out loud.
Ask questions about anything you get stuck on, or ask Ka to rework your material into new cards, quizzes, or notes.
