What parents think, and their children too
“It doesn't do the student's homework for them, it helps them understand the question, the instructions and the exercises […] My daughter, who has ADHD, uses it. […] I highly recommend Sharp.”
“Before using Sharp, my overall average was below a C. […] I revised on Sharp for two days before the test […] and I got an A!! […] Now I have a B+ average thanks to Sharp.”
“A very handy app, really useful! It has helped my children enormously at school!”
“After a few days of using it, I find it really useful, it helps me a lot and I managed to get an A- average in maths when I had a D before installing Sharp. Perfect!”
“It really helps you understand topics and gives you little quizzes to practise. […] I was struggling with Ohm's law in physics, and in 5 minutes I had understood everything.”

Our approach: help, never do it for them
Sharp is built on artificial intelligence. We designed it around three commitments.
It guides, it doesn't do the work for them
Sharp asks questions and gives hints, never a ready-made answer. It's slower than copying, and that's deliberate: that's how you learn.
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 in the loop
From your parent account, you see what your child is working on and you set the screen rules.
Questions from parents
Isn't ChatGPT enough?
ChatGPT gives the answer, your child copies it down, and on test day they're on their own. Sharp does the opposite: it never gives the answer, it helps them find it.
Why not private tutoring?
A good private tutor is precious, and Sharp isn't trying to replace them. But Sharp is there every evening, in every subject, for far less. It can complement private lessons, or be enough on its own, depending on what your child needs.
How does Sharp work?
Your child sends their exercise as a photo, in writing or by voice. Sharp is built on artificial intelligence, framed by a teaching method that follows the national curriculum for their year: it spots where they're stuck, explains, then lets them take the next step.
