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.

Whether you are trying to break out of a rank plateau or just want to understand why your win rate drops at certain times of day, LOL Brain gives you the numbers behind every decision. Every tool is free and works with any ranked League of Legends account.

Tools Overview

The Draft Calculator lets you analyze any 5v5 team composition before you lock in. Paste both teams and get an AI-generated win probability based on champion synergies, counter-matchups, and team comp archetypes. It covers all 170+ champions and updates with every patch.

The Performance Tracker logs your KDA, CS per minute, damage per minute, gold per minute, and overall win rate across your most recent matches. You can spot trends over time, compare your current stats to your previous performance, and see which champions are actually carrying your climb.

The Tilt Detector analyzes your match history to find sessions where consecutive losses caused your performance to drop. It calculates your normal win rate versus your win rate during tilt sessions and shows you exactly how much LP tilt is costing you over time. Players who learn to stop after two or three losses tend to maintain significantly higher overall win rates.

Best Time to Play breaks down your win rate by hour of day and day of week. Most players have a two to four hour window where they consistently perform above average. This tool helps you find that window so you can queue during your peak hours and avoid playing during your worst ones.

Should I Queue? combines your recent form, current tilt level, time of day, and session length into a single readiness score from 0 to 100. It tells you whether now is a good time to play ranked or if you should take a break and come back later.

How It Works

Getting started takes under a minute. Sign in with your Google account, link your Riot Games summoner name and region, and LOL Brain automatically imports your match history. From there, every tool updates in real time as you play more games. There is nothing to install and no desktop client required - everything runs in your browser.

LOL Brain uses the official Riot Games API to fetch your match data. Your information is never shared with third parties, and you can disconnect your account at any time from the settings page. The platform is built for ranked solo queue players on any server who want a data-driven edge without the complexity of spreadsheets or manual stat tracking.
