Language learning, reimagined
Lingua Francai turns your real conversations — with your partner, your parents, your friends — into a language lesson. Chat normally. Learn naturally.
How it works
A partner, a parent, a friend. They don't need to be learning a language — they just need to be someone you'd normally text. Connect by phone number or a private code.
You write in English. They see Spanish. They reply in Spanish. You see English. You're both just... talking. And you're both learning, even if only one of you is trying to.
Save sentences from real conversations. The app builds vocabulary drills, conjugation exercises, and grammar lessons from what you actually said — not what a textbook thinks you should say.
Who it's for
"You have to talk to your parents anyway."
For family"Lingua Francai is for lovers."
For couples"Real friends will Lingua Francai for you."
For friendships"Learn to say the things you actually say."
For everyoneWhat's inside
Write in your language. Your contact reads in theirs. Group chats work too — everyone sees their own language.
Vocab, conjugation, sentence completion — all generated from sentences in your actual conversations, not generic textbook phrases.
See exactly where you struggle. Performance breakdowns by tense, gender, verb form — so you can focus on what actually matters.
Story-based listening practice with speed control. Tap any sentence for a full grammar breakdown — on demand, not on a schedule.
Translate sentences out loud. The app checks your pronunciation and meaning, not just whether you hit the right syllables.
Multiple people, multiple languages — everyone reads in their own. Your friend group doesn't need to all be learning the same thing.
