A program that remembers every class and prepares lessons from the textbook together with the teacher. It sees the page, suggests how to run each task and says why. The teacher decides.

Each class has a journal kept along the textbook: what was done, what worked, what was hard. The next lesson starts from where the last one ended. A note after the lesson is optional.
The suggestions come from a method base: approaches, lesson stages and task types, each with an explanation and a source. It is kept in plain text files that can be read and added to.
On the teacher's side there is a character on a screen, in a phone or a tablet. It listens, and the camera shows it the textbook page.

Memory between conversations already works: my desk robot at home talks and remembers what was said to it. There is a first version of the method base for English lessons. The companion app itself does not exist yet. The first pilot is planned with English teachers.
The companion lives on a screen, as a character in a phone or a tablet. The desk robot stays my home robot.
The project took its present form: a companion that prepares lessons with the teacher and remembers each class.
Tried another form: an assistant that listens to a lesson and counts how the teacher runs it. On my own recordings I wait less than a second after a question.
Started as an assistant for the hours before a lesson, in a small robot on the desk.
