Educational use
Examples and explanations help you study. AI output can be incorrect, incomplete or inconsistent with a position. Verify important claims using the board, legal moves, cited rules and engine evidence. No rating improvement, title, tournament result or service availability is guaranteed.
Accounts and usage
Keep account credentials private. Do not bypass request limits, interfere with the service or upload content you are not entitled to use. Reading and board setup are public; sending AI questions and beginning guided coaching require sign-in. Free usage is limited to protect service capacity.
Fair play
Use analysis tools for study and review in accordance with the rules of your competition or playing platform. Do not use outside assistance during a game where it is prohibited.
Content and corrections
Historical articles retain their existing attribution. New examples are composed teaching positions unless a verifiable game source is supplied. Third-party material remains subject to its own terms. Report factual problems with the relevant page and position so they can be investigated.
