What Is LOL Brain?

LOL Brain is a free, AI-powered toolkit for League of Legends players who want to climb with data instead of guesswork. It combines draft analysis, performance tracking, and behavior insights into one place so you can make better decisions before, during, and after your ranked sessions.

The Draft Calculator lets you analyze any 5v5 team composition and get an AI win probability before you lock in. The Performance Tracker logs your KDA, CS/min, and win rate across your last 20 games so you can spot trends. And the behavior tools — Best Time to Play, Should I Queue?, and the Tilt Detector — help you understand when you play best and when to stop before tilt costs you LP.
