What it does

A look at kioki.app

Kioki is a flashcard app for learning vocabulary and real phrases across 12 languages. Every card includes images and native-speaker audio so users learn words as they sound in real life. The app uses spaced repetition to schedule reviews at the optimal moment before forgetting.

Kioki offers multiple ways to build decks: users can upload photos of textbook pages or PDFs for AI-powered flashcard generation, import existing decks in CSV, Anki, or plain text formats, or browse hundreds of pre-made decks covering real phrases and exam vocabulary. The app includes a Listen mode that plays decks like a podcast, allowing hands-free review during commutes or exercise.

Users can create and study on iOS or the web at study.kioki.app, with progress syncing across devices at no extra charge. Offline study is available in the iOS app.
