AI Chess Brain · For Discord
Chess Brain dissects every Lichess game you play — engine-verified blunders, opening missteps, endgame breakdowns — and delivers a full coached analysis straight to your Discord. Private by design. Open source. $5/mo.
Card required, cancel any time. No bot-server provisioning, no Lichess token of your own — install in any server you manage.
Four things Chess Brain does automatically, after every game.
Polls your public Lichess games every 10 minutes. No manual uploads, no PGN dragging — the brain is always watching.
Critical moments are found by the engine, not guessed. The AI only writes its analysis after the numbers check out.
"Why was move 17 bad?" "What should I have played?" /ask keeps the full game in context so answers are always specific.
Stripe → Add to Discord → /setup. No tokens, no servers, no sysadmin. The brain moves in immediately.
A look at what shows up in your channel after every game.

why was Bxh3 bad? what should I have done?gxh3 Qxh3 Black's queen has no real follow-up — and you've handed back the bishop pair plus weakened the king. The engine prefers Rfd1: it doubles on the open file and keeps pressure on d6. The pawn on h3 wasn't going anywhere; activity over material was the lesson here./setup lichess:<username> channel:#chess.You need one with admin rights to add Chess Brain.

No. We use Lichess's public games API with a polite User-Agent
and stay well under their rate limits. Lichess explicitly allows this kind
of read-only commercial use.
No. Chess Brain only analyzes completed games. It never assists during play, doesn't connect to your client, and never sees your live position. Use it the same way you'd use a coach reviewing your games afterward.
Yes. Run /billing in your server to open Stripe's customer
portal — cancel, update card, or download invoices in two clicks. No
retention emails, no friction.
The minimum required to post analysis: your Lichess username, game IDs we've already coached (so we don't repeat ourselves), and the analysis text we publish to your channel. Full PGNs are pulled from Lichess on demand and not retained. See Privacy for specifics.
No. Chess Brain only knows about your games, inside your server. There are no leaderboards, no rating curves stored, no benchmarks against other subscribers. The whole point is a private conversation between you and the engine — no social pressure, no surveillance, just honest coaching.
