A Chess Coach Bot — Not One You Play, One That Coaches You
Most chess bots are opponents you try to beat. This one is different: it reads the games you already played, finds the mistakes you keep making, and tells you what to work on next.

An engine or opponent you play against to practice. Useful — but it will not tell you why you lost or what to fix.
