## What is MainLine?

MainLine is a chess trainer built for pattern recognition. Use spaced repetition to remember tactical motifs, endgame ideas, and positions from your own games instead of rereading them and forgetting them.

Import your Chess.com or Lichess games, find the mistakes and recurring themes that cost you points, and turn them into short interactive drills you can review in minutes.

Why players use MainLine:
- Spaced repetition that surfaces the patterns you're most likely to forget
- Interactive drills that build fast recall on the board
- Game import from Chess.com and Lichess for targeted review
- Training for tactics, endgames, puzzle themes, and critical lines
- Daily reminders, streaks, and progress tracking
- Challenge yourself with daily puzzles

Whether you're sharpening tactical awareness, improving pattern recognition, or making game review more useful, MainLine helps you remember what matters.

Download MainLine and turn review into stronger chess instincts.
