Adaptive language coaching
TierTalk helps learners stay inside the right CEFR lane.
Start a topic-based practice chat. The tutor keeps asking follow-up questions, points out recent mistakes, and gives concrete tips after each answer.
Level-aware prompts
The conversation stays calibrated to A1 through C2 instead of drifting into random difficulty.
Topic-led sessions
Travel, work, food, technology, or a custom topic you want to rehearse.
Correction plus continuation
Each response gets quick feedback and then a second tutor message that keeps the dialogue moving.
