Visual interactions

Brilliant-style learning, built in

Each lesson follows the same visual-first flow: manipulate, get feedback, master.

Manipulate first

Every lesson starts with visuals you drag, tap, plot, or reorder — not passive reading.

Check understanding

Each scene validates your work instantly with feedback tied to what you did on screen.

Lock in mastery

A final visual checkpoint confirms you can transfer the idea — progress syncs when you sign in.
