AI Language Speaking Tutor App

Build a mobile AI speaking tutor that runs real conversations instead of flashcards.

In plain English

Verbi is a phone tutor that holds a real spoken conversation with you, a different kind of practice from flashcards. It listens, replies, and corrects you gently while you talk. Learners can start free, then pay a subscription to unlock more speaking time and more languages. They want practice that feels like talking with someone patient. The AI does almost all of the conversations and also handles billing, while the person running the app plans what gets taught, shares short demo videos, and answers support questions.
