Do I need an account or payment to use chess-analysis.org?

Updated

No. According to the site's own description, you can analyze chess games online for free with Stockfish, and no sign-up is required. You paste a PGN or import a game from Chess.com or Lichess, and the analysis runs in seconds. That said, the site also has a subscribe page and a "Buy Credits" option, so paid features or usage limits may exist beyond the free basic use. Check the current terms on the site before relying on it for high-volume or advanced analysis.

What the free, no-account path covers

The advertised workflow is:

  1. Open chess-analysis.org.
  2. Paste a PGN, or import a game from Chess.com or Lichess.
  3. Let Stockfish analyze it.
  4. Review mistakes and best moves.

Expected result: an engine-backed review of your game without creating a login. This is the core use case the site promotes, and it matches the "no sign-up required" claim.

Where payment may come in

The site's footer includes a subscribe link and a "Buy Credits" entry, which indicates some form of paid access exists. The available information does not specify:

  • What the credits are used for
  • Whether free analysis is capped (games per day, depth, or features)
  • Whether subscribing removes limits or unlocks extra tools

Because those details aren't stated, don't assume the free tier is unlimited. If you plan to analyze many games or want deeper reports, check the subscribe page and any pricing or terms pages directly.

Practical checklist before you commit

  • Casual review of a few games: start with the free, no-account flow. It should be enough for spotting blunders and reviewing best moves.
  • Heavy or repeated use: look for any stated limits on the free tier, then compare against what credits or a subscription provide.
  • Sensitive or saved data: if you want stored records, note the "Records" link in the footer and confirm whether that requires an account.
  • Current terms: pricing and feature limits change; verify on the site rather than relying on older descriptions.

Bottom line

For basic game analysis, no account and no payment are needed per the site's own description. Paid options exist in the form of subscriptions and credits, but what they unlock isn't specified in the available information, so treat the free tier as the starting point and confirm current limits and pricing on chess-analysis.org itself.
