Overview - JustTalk AI Help Center

JustTalk helps you get better at speaking English by speaking — with a real teacher in live lessons and with AI characters in between. Everything you say feeds one shared progress profile: vocabulary, grammar, pronunciation, and mistakes. When your teacher invites you, you get access to two connected surfaces:

The web app

app.justtalk.ai — book and join live lessons, and review the AI report after each lesson (vocabulary, grammar, mistakes, transcript).

The AI practice app

chat.justtalk.ai (also on iOS) — practice speaking any time with AI characters, role-plays, IELTS mock tests, and a progress coach.

One progress profile across both

The two apps share the same account and the same data. Words you use in a live lesson and words you use talking to an AI character both count toward the same vocabulary, grammar, and pronunciation progress. Your teacher sees all of it; so do you.
