# League MBTI Analytics

> A free, open-source League of Legends analytics tool that maps your in-game performance to an MBTI personality archetype. A free alternative to yearin.lol and op.gg with unique AI-powered personality analysis.

## What It Does

League MBTI Analytics analyzes your 2026 League of Legends match data across all game modes (Ranked Solo/Duo, ARAM, Arena, Quickplay, Flex, and rotating modes) and produces:

1. **MBTI Personality Type** — Derived from 8 gameplay dimensions using z-score normalized behavioral analysis
2. **Gamer Archetype** — A named persona (e.g., "The Grandmaster", "The Field Marshal") with detailed description
3. **AI-Generated Narrative** — Personalized storytelling about your playstyle evolution, strengths, and predictions
4. **Visual Analytics** — Growth charts, champion mastery breakdowns, and match history tables
5. **Shareable Cards** — Canvas-rendered social media cards showing your MBTI archetype and stats

## MBTI Calculation Algorithm

The system evaluates 4 MBTI dimension pairs using real match statistics:

- **E vs I (Extrovert/Introvert):** Assists/game, vision/min, support rate vs. kills/game, DPM
- **S vs N (Sensing/Intuitive):** Low deaths + stable KDA vs. high-risk pace + damage output
- **T vs F (Thinking/Feeling):** Damage/gold efficiency vs. vision + support utility
- **J vs P (Judging/Perceiving):** Champion specialization + role consistency vs. champion/role diversity
