“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.

Ratings and reviews

A little under a year ago, I was thinking about programming a basic openings repertoire maker/trainer for myself. I had come up with a list of features I wanted, and was getting ready to start coding when I ran across Chessbook. It turns out that this app was everything I was looking for and more! It's also under active development, and keeps getting better. I would consider this app the definitive way to truly learn your openings.

Great app, you can get a lot out of it for free especially as a lower level player. Because let's be honest, most players don't need more than 100 lines for each color. However I give 4 stars because it's missing some kind of notification system. It will give you a game to review and moves to practice but I would an option to be reminded.

Not perfect, and still needs a lot of work. I don't normally subscribe to services like these but if you put work into this tool, it basically replaces all your paid chess opening resources, such as books or chess*ble, by enabling you to simply write a personalized book for yourself. I would prefer it not to be subscription based however. Edit: I have a new phone now and the app no longer works properly. Also the same common bugs have been around for years. Dev doesn't care. Very frustrating.
