Memorize hard vocabulary with mnemonics and smart spaced repetition.
Review scheduling adapts to your performance so difficult words appear more often and known words fade into the background.
Each word is supported by a memorable association designed to create a strong mental hook, making recall faster during an exam.
Curated word sets target the academic vocabulary that recurs across GRE, GMAT, and IELTS verbal sections.
A stripped-back study flow keeps you on reviewing words rather than managing settings or browsing decks.

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.
