Terms of service
Last updated: 3 November 2026
The service
Chess Coach analyzes finished chess games with the Stockfish engine and returns the results to your AI assistant. The service is provided "as is", without guarantees of availability or accuracy.
Fair play
You may not use Chess Coach to get help during a game in progress, on any platform. The service only analyzes finished games, and we may block accounts or requests that try to get around this.
Fair use
Every new account gets a free trial of 14 days from its first use, with the same limits as Pro and no payment details; existing accounts get it once, from their first use after 3 November 2026. When the trial ends, the account moves to the Free plan unless you subscribe. Free accounts include one game analysis per day. Plus includes 10 per day. Pro is unlimited subject to fair use, up to 20 analyses per day. Reports and drills count one analysis per 8 games they analyze. We may limit automated or abusive traffic to keep the service available for everyone.
Payments
Plus ($3.99 or €3.99) and Pro ($7.99 or €7.99) are monthly subscriptions billed through Stripe. EU prices include VAT. You can cancel at any time and keep access until the end of the paid period.
Third parties
Chess Coach is independent and is not affiliated with, endorsed by or sponsored by Chess.com, Lichess, Anthropic or OpenAI. Game data comes from their public APIs and remains subject to their own terms.
Liability
To the extent permitted by law, Chess Coach is not liable for indirect losses arising from use of the service. Nothing in these terms limits rights you have under consumer protection law.
