Questions
Is Backrank free?
Yes. Import your games, train on your mistakes, and learn a couple of openings on the free plan. Pro unlocks unlimited cards and unlimited openings.
How do you find my mistakes?
We analyze every move of your recent games. Blunders and missed tactics automatically become puzzles you practice with spaced repetition.
How do you get access to my games?
All we need is your username. We use the official Chess.com and Lichess APIs to fetch and analyze your most recent public games.
What is spaced repetition?
A science-backed alternative to cramming. We bring each position back right before you would forget it: get it right and it returns later, miss it and it comes back sooner, so your weak spots get the most practice.
Can I train openings too?
