Questions

Good to know

Does my child need to know how to code?
No. We start from zero. With today's AI tools, students build working apps and games by describing what they want and improving it step by step.
Which ages is the club for?
Every student is welcome. Groups are formed by age, so younger and older students each work at the right level.
Is it safe?
Yes. Privacy, honesty and responsible use are part of every session. Students never enter personal data, and all tools are used under supervision.
Won't this make cheating easier?
We teach the difference between using AI to learn and using it to skip learning, and why that matters for their own future.
What does my child need to bring?
A laptop or tablet. Access to the AI tools during the sessions is included in the price.

Places are limited to 15 per group.
