I've been using chatgpt to tutor my son to improve his writing skills. It actually works quite well and the lessons adapt to his skill level. I seeded it with the curriculum and marking guidelines for his school year. Each lesson is timeboxed to 30 minutes and he stops if the lesson goes over time. I then feed this back into chatgpt and it adapts the lessons appropriately. It's helped quite a bit with a definite improvement in his writing skills. He actually wants to do this instead of school as he feels he gets a lot more out of it!
