LOL Brain
What it is
LOL Brain is a free League of Legends toolkit for draft analysis, match tracking, and behavioral insights. Its draft calculator assesses lane matchups, team synergies, composition archetypes, and estimated win probability using ranked data. The tracker records recent-match KDA, CS per minute, damage per minute, gold per minute, and win rate. Behavior tools include tilt detection, results by hour and day, session patterns, and a Should I Queue readiness score from 0 to 100.
The browser tools need no installation, and 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; LOL Brain receives the user's name and email, but says it does not store the Google password. A Windows companion for Windows 10 and 11 displays live champ-select picks, counters, ban targets, synergy reads, and win probability. It needs no account, may trigger a Windows SmartScreen warning, and updates itself after installation. LOL Brain says its statistics and recommendations are estimates and do not guarantee accuracy or match outcomes.
