Synapse is a language learning app built on how your brain actually works. Whether you're a beginner or brushing up, Synapse combines proven neuroscience techniques with tools that make learning stick.

SMART FLASHCARDS
Build vocabulary with spaced repetition powered by the FSRS algorithm. Create cards from translations, AI-generated definitions, or snap a photo of any object with Language Lens to instantly learn what it's called in your target language.

LEARN WITH MUSIC
Turn your favorite songs into language lessons. Synapse lets you sing along with word-by-word karaoke, switch between vocals and instrumentals, and slow down playback to catch every word. Music builds lasting memory connections that textbooks can't.

EAR TRAINING
Train your ear to hear the sounds that matter. Synapse generates minimal pair exercises tailored to your native and target language, helping you distinguish the sounds that native speakers hear effortlessly.
