Free. No ads. No account. Just chess and a weird little friend who has opinions about your moves. Chess-Buddy is a chess game where your computer opponent also talks with you using a powerful local LLM, Qwen 3 trained at 1.7 Billion parameters. This Chat system has been wrapped and designed to conform to this game giving a dynamic personality to the gameplay that feels alive and rich with a friendly buddy to play with. I like playing chess on my phone but I really like playing with a person. This isn't quite as nice as playing casual chess with a friend but it's pretty nice. Play chess against a real engine (the chess side of the AI is running on stockfish, the leading open source chess engine that everyone agrees is really great, with also selectable difficulty levels). After almost every move, Buddy reacts — with a short line, a funny face might happen, and occasionally a little shade. You can chat freely between moves too. Buddy will respond. It's less like playing against a computer and more like playing against a friend who happens to be very good at chess but awkward at conversation, Not to say it is a bad chat LLM it's just not set up to work like a personal assistant anymore, the conversation is with a LLM that is essentially now Chess-Buddy. Everything runs on your phone. No internet required. No account. No ads. No subscription. The chess engine and Buddy's brain are built in. --- CHESS • Full rules: all legal moves, castling, en passant, pawn promotion with a piece picker • Four difficulty levels — Friendly (800), Casual (1200), Competitive (1600), Expert (2200) • Undo moves and reset anytime • Game saves automatically — pick up exactly where you left off BUDDY • Reacts to the game with short, personality-driven commentary • 11 animated face states — Buddy goes mindblown when something wild happens • Chat freely: ask for help, vent about your last move, just hang out • Runs entirely on-device with a local AI model — no data leaves your phone DESIGN • Bright, friendly, cartoon — not a dark chess robot • Tap or drag pieces, whichever feels natural • Haptic feedback for captures, check, and checkmate • One screen. No menus to get lost in. ChessBuddy is made by Adrondak LLC.
