Anyone can learn a language. At any age.
Ear first. Mouth next. Play always.
Stories that teach you to speak
Illustrated story podcasts feed you the language the way your brain wants it — scene by scene, episode by episode. No vocabulary lists.
Why stories work →Stop translating. Start speaking.
Words stick when they connect straight to images and moments — not to your native language. Synapse never asks you to translate.
Why translation holds you back →Fluency forever, not streaks forever.
True spaced repetition (FSRS) schedules each word right before you'd forget it. Miss three nights? Nothing breaks — the schedule bends to you.
No such thing as too old
The “critical period” is a myth, and it survives because it is convenient: it lets you stop. The science says adults who stay focused, learn in small bits, and sleep on it rewire just as well. We wrote down what we believe, with the research linked.

One day, someone speaks — and you just answer.
Most apps count your streak. Synapse builds that day — a few minutes at a time.
