Hey everyone! I'm Antoine, the maker of ChessAtlas. I built this because I kept running into the same frustration: I'd spend hours studying an opening, feel confident, then completely blank on it in a real game two weeks later. The problem isn't learning openings. It's remembering them. ChessAtlas connects to your Lichess or Chess.com account, imports your games, and shows you exactly where you went off-book. Then it uses spaced repetition to drill those lines until they're second nature. You only review what you're about to forget. A few things I'm proud of: Deviation finder - import your games and instantly see where you left your prep. Spaced repetition training - based on FSRS (Free Space-Repetition Scheduler). Course library - fork a ready-made repertoire or build your own from scratch. Works with your games - pull directly from Lichess and Chess.com. I'd love to hear what you think, especially if you've struggled with opening retention. What's your current workflow for studying openings?
