The Challenge
A great language teacher can reach maybe 30 students in a classroom, not 30,000 online. Learners past the beginner stage kept hitting the same wall: real speaking practice meant paying a human tutor by the hour, working around their schedule, and feeling judged every time they made a mistake. Most language apps made that worse by focusing on vocabulary drills and multiple-choice grammar, not actual conversation.
The client's product needed to put unlimited, judgment-free speaking practice within reach of any student, anywhere.
The Solution
New York App Devs built Teacher AI as a mobile app for iOS and Android, giving every student their own AI tutor in their own language, modeled on real, recognizable teachers instead of a generic chatbot voice.
Speech-to-text turns what a student says into text, the AI drafts a reply and a gentle correction, then speaks it back in the teacher's cloned voice.
