For curious children & their grown-ups · Ages 9–16
A little play.
A small change.
Something you built together.
You do not need to be the coding expert. Pick a project, let your child drive, and ask what they think will happen. Work in short bursts, at your family's pace.
The browser introduction needs no installation, payment, child account, or AI key. Use a laptop or desktop for coding; phones are good for reading along. Internet is needed to load the workspace and 3D tools.
