A Chessigma alternative: Lumichess vs Chessigma

Chessigma and Lumichess do the same core job. Type a Chess.com or Lichess username, or paste a PGN, and Stockfish reviews the game in your browser, with no daily limit and no account. This page sets the two side by side, including the places where Chessigma is ahead.

The short version

For reviewing a single game, the two are close. Both give unlimited reviews, both grade every move, both show accuracy and an estimated game rating for each player, and neither needs you to sign up first.

The differences sit around the review. Lumichess labels moves with the names players already know and reads your last 1,000 games in its Profile Report. Chessigma has phone, desktop and browser-extension apps, six languages, and a coaching kit called Supercoach.

Lumichess rows come from our own build. Chessigma rows come from its homepage, pricing, download, developer and analysis pages, its llms.txt file, and a sample game report we opened on its site. Products change, so check each site before relying on a detail.

Where the two are the same

Both run Stockfish on your own device rather than on a server, which is how both can review every game you have played. Both load your recent games from a Chess.com or Lichess username, both take a pasted PGN or a .pgn file, and both show an evaluation graph, accuracy for each side and a game rating. Both also have an MCP server, so AI assistants such as Claude and ChatGPT can use them as a chess tool (ours is here).

Where Lumichess is different

Familiar move labels. Each move lands in one of eleven outcomes: Brilliancy, Great, Best, Excellent, Good, Book, Inaccuracy, Mistake, Missed, Blunder and Forced. Chessigma uses its own names in its report, from Sigma at the top down to Clown. Which you prefer is a matter of taste; ours read the same as the labels you see elsewhere.

Every game in one place. Your games library lists your Chess.com and Lichess games together, one click from a review.

A report on 1,000 games, not one. The Profile Report reads your last 1,000 games and scores six skills: openings, tactics, endgames, conversion, time and resourcefulness, each against players at your own rating. Insights charts your whole history on both sites. Chessigma’s closest equivalent is its Chess DNA report, which covers five areas and is part of its Supercoach plans.

An AI Coach built on your games. The AI Coach finds the mistakes costing you the most rating and builds 15 minutes of training a day from your own games. Around it sit over five million puzzles, a Woodpecker trainer and live games through your Lichess account.

Official ratings too. Look up any player’s FIDE rating, estimate your own FIDE strength from your online results, and compare two rated careers head to head.

Where Chessigma is ahead

Chessigma has iOS, Android and desktop apps and a Chrome extension, and its site comes in six languages. Lumichess is a web app you can add to your home screen, in English.

Which one should you use?

If you want every game reviewed with familiar labels, an AI Coach that trains you on your own mistakes and a clear picture of your play across hundreds of games on both sites, start with Lumichess. If you need a native phone app, Chessigma has one. Both are quick to test: paste the same game into each and compare the reports.
