Kioki

Kioki is an AI-powered language learning app designed to help you master vocabulary and real-world expressions for both conversations and standardized exams like TOEFL, TOPIK, and AP languages. Instead of relying on static word lists, Kioki lets you generate flashcards instantly from PDFs, notes, documents, or images using AI. You can also access ready-made decks organized by level (beginner to advanced) and language pairs, so you always know what to study next. Built on spaced repetition—a Harvard-backed study method proven to improve long-term retention—Kioki helps you retain vocabulary and expressions more effectively than traditional study methods. Whether you're preparing for an exam or improving your speaking ability, Kioki ensures you focus on the words and expressions that actually matter.
