ChessBuddy AI is an innovative browser extension designed for chess enthusiasts using lichess.org. This free add-on provides a compact chat interface that allows users to interact with an advanced AI, simulating the experience of having a personal chess coach. With three specialized modes—Coach, Analyst, and Assistant—ChessBuddy AI caters to players of all skill levels, offering targeted exercises, detailed game analysis, and direct answers to chess-related queries.

In addition to its coaching capabilities, ChessBuddy AI features text-to-speech functionality, allowing users to listen to AI responses through customizable voice settings, and speech recognition for hands-free interaction. Designed exclusively for Lichess, this extension requires an active chessbuddy.ai premium subscription for full access and is intended solely for learning purposes, ensuring fair play by not allowing use during live rated games.
