Text isn't a limitation — it's an advantage for deep language learning.
In text chat you're not rushed. Think through a phrase, re-read the correction, memorize it.
Dialogue history, new words, corrections — all available for review. In spoken conversation, this is lost.
Emails, messages, LinkedIn, team chats — written English is needed more often than spoken.
Corrections are visual: ❌ your phrase → ✅ correct one. In speech, errors slip by unnoticed.
No card, no schedule. Just start a conversation — the AI tutor adapts to you.
