Everything this site is for is free, and will stay free. This page is the promise, written down so it can be held against us.
Free, and staying free
- Every game review. Every game, as often as you like, with no account and no daily limit — yours and the famous ones alike.
- Every lens. The forces on the board, how hard a move was to find, the turning point, the chapters, the tension and the soundtrack.
- Playing. The engine, a friend by link, and real opponents through your Lichess account.
- The daily game, the puzzles, the puzzles from your own mistakes, and the whole library with its annotation.
- Importing your games from Lichess, Chess.com or a PGN file — and they stay in your browser, not on our server.
Why it can stay free
The expensive part of a chess site is the engine, and ours does not run here: Stockfish runs in your browser, on your machine. A review costs this site nothing but the few hundred kilobytes it takes to send you the page. The rest is static files and one small database, which is cheap enough that nothing about the way this site works needs to change to pay for it.
What will never happen here
- No ads interrupting a game. None between moves, none over the board, none anywhere.
- No crypto, and nobody is paid to play.
- The review is never behind a price. Not a trial, not one a day, not a better version for money.
- Your games are not sold, because they are not ours: imported games live in your browser.
And there is nothing to buy
There is no donate button, no supporter tier and no shop — not hidden away, simply not built. If that ever changes it will be for extras beside the things listed above, never by taking one of them away.
