The useful question is not whether Arco can summarize a lesson. It can. The useful question is whether the summary makes the next lesson easier to start. That depends on reducing teacher rework and making the takeaway legible to the student.
- Save the original summary when accuracy matters most.
- Generate a simpler variant when the same notes need to reach a parent or a younger student.
- Share only the pieces that keep the next session moving: goals, assignments, and the one correction that cannot be lost.
Arco works best here when it shortens the gap between what happened in the room and what the student can still act on three days later.
