Learn 200+ ML Algorithms by Building Them

Implement 200+ ML algorithms from scratch with interactive visualizations and learn the math behind AI.

In plain English

Learners can build many of the math methods behind AI themselves and watch pictures that show what the math is doing. The idea is to understand each method by constructing it, not only by reading about it. They can start free and pay a student-friendly subscription when they want more, because formulas alone are easy to forget. The AI does most of the explanations, the practice help, and the billing. The person running the site still checks that the lessons stay correct, helps learners, and reaches them through search and student groups.
