With ChatGPT, the homework gets done. But what did they learn?
Your child snaps a photo of the exercise, the AI gives the answer, they copy it down. The homework is handed in, but nothing is understood. And on test day, there is no AI to help.
AI should make children smarter, not more dependent
We believe in responsible AI. For us, that means three things.
It guides, it doesn't give the answer
Faced with an exercise, Sharp asks the right questions and gives hints. Your child finds the solution on their own, and remembers it.
A safe space, just for school
Sharp stays on school topics. If a sensitive subject comes up, it responds with care and points your child to a parent or an adult at school.
Parents keep an eye on things
With your parent account, you see what your child is working on, for how long and in which subjects.

The best of AI, working for the student
The power of the most advanced AI models, guided by real teaching methods.
