Couplet
Finish real topics and actually speak the language
Couplet teaches a language by ear, one real-life scenario at a time. Hear each line in English, then in another language— ordering dinner, small talk, a phone number, 1,000+ topics in all. For every topic, a small set of high-frequency phrases covers ~90% of what you'd actually say, so each deck is finite and finishable, not an endless vocab list. No streaks, no feed — play it like a podcast and finish topics in minutes. English→French today; Japanese and more coming.

Hey Product Hunt 👋 I've started a lot of languages and finished almost none. The apps always felt the same — endless feeds, streaks guilting me back, thousands of rare words I'd never actually use. Busywork, not progress. Couplet starts from one observation: in any real situation, a small handful of phrases does almost all the work. Order dinner, ask directions, make small talk — the same essential few come up again and again. So each deck distills a topic down to the critical phrases that cover ~90% of that scenario. There's a small design choice doing a lot of the work: you hear the English first. In that beat before the answer, your brain can't help but reach for the phrase itself — and then the native line lands as either confirmation or correction. That quiet act of trying-then-comparing is what turns "I recognize that" into "I just know it," and it makes every pass far stickier than passive listening. And because each topic is a finite deck, you reach the last card and you're genuinely done. No streaks, no feed — play it like a podcast while you cook or commute. French and Japanese are live today with 1,000+ topics, and you can vote for the language we build next. Which language or topic would you want first?
