Chessly Elo Prioritizer

Chessly courses are fantastic, but they often cover "Grandmaster Theory" that players at 1200 or 1600 ELO rarely face. A typical course can have over 100 different variations—how do you know which ones to study first?
The Chessly Repertoire Prioritizer helps you optimize your study time by answering three critical questions:
"Will I actually see this move in my games?" (Frequency Check)
"Is this line successful at my rating level?" (Win Rate Analysis)
"Should I focus on Rapid or Blitz lines?" (Time Control Filtering)
🚀 How it works:
The extension scans your active Chessly course, extracts the moves, and instantly cross-references them with the Lichess Database. It presents everything in a clean, full-screen dashboard.
✨ Key Features:
📊 Real-World Frequency: Sort every line in your course by "Total Games Played." Identify the 20% of lines that appear in 80% of your games.
🎯 Custom Filters: Don't care about Bullet chess? Filter by Time Control (Blitz, Rapid, Classical) and Rating Range (e.g., 1600-1800) to see stats relevant to you.
🚦 Visual Win Rates: Instant color-coded bars show White vs. Black win percentages for every single variation.
💾 Multi-Course Support: Builds a persistent library of your repertoires. Compare lines across different courses (e.g., Vienna vs. London System).
⚡ Lightning Fast: Uses advanced caching and direct API connections to load data in seconds.
🔒 Privacy & Requirements:
Requires a paid Chessly.com account. This extension strictly respects Chessly's paywall and only extracts data from courses you own.
Privacy First: Your data stays on your device. We do not track your browsing or store your credentials.
