AI is getting better at spotting grammar patterns and suggesting vocabulary. That is useful. It is also not teaching.
A teacher hears hesitation, chooses when to interrupt, and knows whether a “mistake” was actually a student testing a new structure. A model sees text. It does not sit across from you for 15 minutes and keep the conversation human.
Talkinu’s rule is simple: teachers teach, AI assists. Analysis should arrive after the session, where a teacher can edit it. If a tool cannot be reviewed by the person who taught you, it should not be treated as feedback.
Use models to prepare questions, review a transcript, or drill a phrase. Do not outsource the conversation itself.
