Why Katalume exists
Machine learning becomes durable when concepts move from reading into repeated, purposeful practice. Katalume combines the rigor of coding challenges with the depth of applied ML work in an in-browser judge.
The name
“Kata” is deliberate practice that forges mastery. “Lume” is light or illumination—the moment a hard problem clicks. Together, Katalume represents practice turning into understanding.
