One workspace for more than one chess account
ChessSum brings recorded games from multiple Chess.com and Lichess usernames into one place. You can connect more than one account from the same platform. For example, you might have a main Chess.com account, a second Chess.com account for faster games and a Lichess account. You do not need to choose only one of them.
Start with your usernames
- Sign in to ChessSum and open My workspace → Accounts.
- Select Chess.com or Lichess and enter a username. Add each additional account separately.
- Keep accounts you play on in My accounts. Use tracked players for opponents and other people you want to follow.
- Wait for the import, then open your game history and statistics. Check each account's import status before treating a total as complete.
The current version supports up to 10 tracked accounts per member. Adding a username imports public chess data; it does not require giving ChessSum your chess-site password. Ownership verification is separate from importing a public record.
See what adds up
Explore imported games, wins, losses and draws together, then compare periods or individual accounts. Replay a recorded game on the board. When you want to improve, use game analysis to investigate repeated mistakes and follow relevant lessons.

Connect existing accounts in accordance with the source platform’s rules. Chess.com explains its alternate-account requirements here.
What does not get merged?
Your Chess.com and Lichess logins remain separate. ChessSum does not transfer ratings, change your accounts on those websites or create one official rating. Ratings stay associated with their original platform and time control.
What if games are missing?
An import may still be running, or the source may not have supplied every game. The displayed totals describe the history currently imported into ChessSum. Check sync status and your selected filters rather than assuming an empty result means you never played.
