Kenning's take
What it does
Brilliant teaches maths and coding through short interactive lessons and puzzles instead of videos. Its AI tutor Koji watches how a learner works, gives hints when they are stuck and adjusts to their level without simply handing over the answer. It works on the web and in phone apps.
