LangjeeThe Laziest Way to Learn a Language

No flashcards, no burden, just progress.

Master the Language Through Sentences

Forget word lists. Language lives in context. Langjee trains you through high-quality sentence repetition, targeting vocab and core grammar structures. Japanese, Korean, and Chinese learners get grammar-focused sentences. Spanish, French, and Italian users can drill verb tenses and endings by category. Every sentence comes with definitions, grammar tips, and native-quality audio.

A Repetition System That Actually Works

Our custom-built audio player automates what used to take hours. Shuffle mode, custom repeat counts, variable playback speed for each loop, adjustable pause lengths—it's all designed to give you time to actually speak. Sentences are organized into rotating playlists with automatic review cycles, so you never have to micromanage your study load.
