Chess Openings - ChessAtlas

Build an opening repertoire you actually remember, and stop losing games to lines you thought you knew.

ChessAtlas turns your openings into a simple training routine: learn each line, review it on a spaced-repetition schedule, and connect your real games to catch the exact moves where you went off-book.

HOW IT WORKS
- Build your own repertoire, paste a PGN, or fork a ready-made opening from the library.
- Learn each line move by move, with plain-language notes on the ideas behind the moves.
- Link your Lichess or Chess.com account. ChessAtlas checks every game against your prep and flags the first move where you deviated.
- Drill those mistakes until they stick, with spaced repetition that brings each line back right before you would forget it.

WHAT YOU GET
- Your real games, checked against your repertoire, with the first deviation pinpointed.
- Spaced-repetition review so lines stay in long-term memory.
- Full game analysis with move-by-move accuracy and the quality of every move.
- A library of curated openings you can fork and make your own.
- Read mode that explains the idea behind each move, not just the notation.
- Streaks, levels and a leaderboard to keep the habit going.
- Multiple board themes.

WHO IT IS FOR
Club and improving players who want a repertoire they can trust under pressure, whether you are building your first opening or sharpening lines you already play.
