The best free chess game analysis tool online

Chess players love winning — but engines love telling us why we shouldn't have. That's where Chessigma comes in: a free chess game analysis tool that actually speaks human. No ads, no captcha, no downloading Stockfish-in-a-zip-file-from-2008.

Why bother with game review?

Because studying more openings while repeating the same tactical face-plants is like polishing a windshield while your tires are flat. A five-minute chess analysis session after every blitz binge stacks up faster than another "London System Secrets" course.

What makes this the best free chess analysis tool?

1. One-click import

Drop a Chess.com or Lichess link, or upload a PGN. Punch "Analyze." Done. Your free chess game review shows centipawn loss, move labels, and a color-coded eval graph faster than you can say "why did I play that?"

2. Deep PGN analysis (without the brain freeze)

Tournament file? 200-move epic? Feed it in — Chessigma chews through every variation. Perfect for PGN analysis nerds who crave progress but also value sleep.

3. Branch & explore lines

Hit any move to spin an alternate universe. Test that unsound pawn sacrifice, prove your genius, or confirm you were hallucinating. It's the most interactive chess game analyzer online you'll touch.

4. Works everywhere

Desktop, tablet, phone on the bus. If you can copy-paste a link, or you have a Chess.com or Lichess account, you can analyze chess games online right now.

5. Track progress & players

Create a free account or use without signup to tag mistakes, save reports, and quietly stalk your rival's blunder rate. Every lichess analysis, every chess.com game review free — all in one dashboard.
