How does Oki work?

1. AI Speaking Practice — Have real back-and-forth conversations with an AI tutor that hears you, understands context, and gives instant feedback on grammar and pronunciation. No judgment, no pressure — just honest, helpful corrections every time you speak.
2. Daily Words & Sentences — Build your vocabulary one sentence at a time. Each day brings new words and phrases tailored to your interests — so you learn the English that actually matters to you, not random textbook filler.
3. Smart Flashcards — Swipe through vocabulary decks built around your topics — travel, tech, movies, sport, and more. Spaced repetition shows you each word right before you forget it, making long-term memory effortless.
4. AI Word Deck Generator — Type any topic — “medical terms”, “job interview phrases”, “football vocabulary” — and Oki generates a ready-to-study flashcard deck in seconds. Completely personalised, endlessly flexible.
