What it is

LOL Brain is a League of Legends toolkit for analyzing drafts, tracking performance, and reviewing play behavior. Its draft calculator assesses lane matchups, team synergies, composition archetypes, and estimated win probability using ranked data. Across recent matches, the tracker records KDA, CS, damage, and gold per minute, plus win rate. Behavior features include tilt detection, results by hour and day, session patterns, and a readiness score called Should I Queue, rated from 0 to 100.

The browser tools require no installation; the draft calculator works without an account. Linking a Riot ID and region lets the service retrieve public match history and ranked data through the Riot Games API. Google sign-in unlocks personalized behavior analysis. A Windows 10/11 companion shows live champ-select picks, counters, ban targets, synergy reads, and win probability. The service is free, with all tools available at no charge. It describes its statistics and recommendations as estimates, not guarantees of accuracy or match outcomes.
