A product design question where the obvious feature, answering homework questions, works against the user's real goal. Strong answers design for learning, for the exam, and for the phone the student actually has.

A read-aloud coach that listens and helps can raise reading levels, as one large pilot found. Work offline on a fixed library, process voice only to respond in the moment, and measure reading gains against a control.

Speaking is the skill learners avoid and value most. Design short, scenario-based calls at the learner's level with one correction per turn, and move it into the main paid plan once the cost per minute allows.

Students solve more practice problems with an AI that gives answers, then score worse on the exam. Decide what the tutor may reveal, how it gets the maths right and what you will measure.
