See what is includedOnlyMove tracks the positions and moves you need to remember. Autoplay carries you through mastered moves toward the material due for review, while surrounding moves keep the line in context. Review timing follows your recall of each position.
See how opening training worksLink Lichess or Chess.com and OnlyMove checks your games against your repertoire. Correct repertoire moves reinforce their review cards; a repertoire mistake sends its position back to Learning. Review uncovered positions and add lines for future practice. When exploring a suggested line, you can open it directly in Lichess analysis for further study.
See how games feed spaced repetitionOnlyMove can suggest a starter repertoire from your recent games, with engine checks to help you review the proposed lines. Adjust the repertoire on the board or bring your own PGN. ChessAtlas also offers a starter repertoire from games, so this is a shared capability.
There is substantial overlap in the opening-training workflow. ChessAtlas’s library and mobile features may make it a better fit for you. OnlyMove is an option if you want to build, train and review your own preparation with no subscription or repertoire cap, alongside Lichess for broader analysis and tactical practice.
ChessAtlas describes each variation as a review card with its own schedule. OnlyMove schedules reviews per position and autoplays mastered moves on the way to material that needs practice. Both use FSRS, but that does not establish identical sessions or learning results.
Its free plan includes 200 variations, 2 linked accounts, FSRS training and the course library. Website Premium pricing is $9.99 monthly or $83.88 billed annually, equivalent to $6.99 per month, in US dollars. Premium adds unlimited variations and accounts, game import with analysis and deviation detection.
Yes. Both offer a starter repertoire based on your own games. In OnlyMove, you review engine-checked suggestions from your recent Lichess and Chess.com games, then edit the proposed lines before training.
No. You build your own repertoire, import a PGN or start from suggestions based on your games. ChessAtlas includes a library of ready-made openings that you can copy and adapt.
OnlyMove is built to complement Lichess. We think Lichess already does a fantastic job of game analysis and tactical practice, so our focus is building and remembering your opening repertoire. In Explorer and when reviewing suggested lines, you can open the line directly on Lichess’s analysis board for further study.
