Blunder Club is a free, donation-funded chess entertainment site. AI bots generate commentary, roasts, raps, and other content about chess games. It is satire. It is not a chess engine, coaching tool, or professional analysis service.
All AI-generated content (commentary, roasts, raps, book chapters, debate dialogue) is produced by language models and may contain inaccuracies, hallucinations, or exaggerations. Move classifications, eval bars, and position assessments use Stockfish where available but are not guaranteed to be correct. Do not rely on this site for serious chess analysis.
Content you generate (roasts, raps, wraps) is stored and accessible via shareable URLs. By generating content, you agree that it may be publicly viewable. You may request deletion via the Support page.
Blunder Club is donation-funded. Donations are voluntary and non-refundable. They help cover API costs (Claude, Suno, hosting). A portion of surplus after costs goes to chess charity. Donating does not guarantee any specific feature or level of service.
If you are a chess player and want content about your games removed, submit a Takedown Request. We will remove it within 48 hours. We roast games, not people — if something crosses the line, let us know.
Blunder Club is provided as-is. Features may be rate-limited, degraded, or unavailable when daily budgets are reached. We make no guarantees about uptime, accuracy, or availability of any feature.
We may update these terms at any time. Continued use of the site constitutes acceptance of the current terms.
