“A great free way to build your opening repertoire ... really smooth”—FM Nate Solon

FIND THE GAPS IN YOUR REPERTOIRE BEFORE YOUR OPPONENTS DO
Chessbook calculates your coverage per opening so you always know what to work on.

PICK THE BEST MOVES TO MAXIMIZE YOUR WIN-RATE
Weigh up your options by looking at stats from master games, engine evaluation and results at your level.

ONLY SPEND TIME ON THE MOVES YOU'LL ACTUALLY SEE
Most books and courses are written by masters for masters. Chessbook lets you avoid obscure grandmaster lines and focus your effort on the moves that are common at your level.

TARGETED PRACTICE MEANS YOU'LL NEVER FORGET A MOVE
Chessbook uses spaced repetition, a scientifically proven technique to memorize openings quickly and thoroughly.

COLLECT ALL YOUR OPENINGS IN ONE PLACE
Nobody gets their whole repertoire from a single course or book. Chessbook lets you combine openings from multiple sources to create a custom repertoire just for you.

REVIEW YOUR ONLINE GAMES FOR OPENING MISTAKES
Get instant feedback on how well you're sticking to your repertoire. Chessbook supports both Lichess and Chess.com

LEARN MIDDLEGAME PLANS FOR ANY OPENING
See how top players handle the positions that result from the openings you play.

CHESSBOOK PRO
Chessbook Pro gives you the ability to add unlimited moves to your repertoire! Free users can add 400 moves.

This is by far the best opening repertoire builder and trainer out there. Generous 100 move for white and black makes it very useful even for free. The way it checks your game results and detects when you failed to follow your repertoire and then gives you extra training on those positions is genius.

Ok it's pretty good but it's weirdly glitchy. You can complete a repertoire, on the Sicilian for example, and it will never get to 100% because it will keep telling you to address a move that's not from the Sicilian. Then, even if you get up to 98%, the next time you open the program it might only be at 89%. How does that happen? Is it forgetting?
