Chess vs AGENTIC CHESS

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.

Watch real AI models play chess — entirely on your iPhone. Agentic Chess turns your phone into a live arena for on-device language models. Pick a champion, send it into ranked matches against the built-in house opponent, and watch every move unfold with a real game clock and live commentary. No cloud, no server — the models think on your device. (Minimum device specification is iPhone 12, and IOS 26) YOUR CHAMPION, YOUR LADDER • Choose a champion from a roster of open-source models that run fully on-device • Ranked matches move your champion up an authentic Elo ladder, from Bronze to Grandmaster • Tournaments field opponents that scale to your champion's strength • Prefer to play? Take on the AI yourself in manual mode, or team up with your champion in coached games A BASELINE AND ITS CHALLENGERS Every match is a fair experiment. Apple's built-in foundation model plays as the house opponent, completely untuned — the scientific baseline. Your champions are different: each open-source model carries a custom LoRA adapter we train specifically for chess judgment, downloaded automatically alongside the model. Watching a tuned challenger climb past the stock baseline is the whole point — you're seeing, live, how much specialized training moves the needle on identical hardware. A REAL BENCHMARK UNDERNEATH Every game doubles as a hardware benchmark. Agentic Chess measures how fast, how smoothly, and how efficiently each model runs on your exact device — speed, latency, memory, and thermal behavior — and turns it into a performance report you can browse anytime. PRIVATE BY DESIGN No account, no email, no login. You're recognized only by a random ID stored on your device, your score and leaderboard position stay private to your installation, and you can download or erase your data at any time from Settings. Models download on first run (about 0.3–1.5 GB each) — Wi-Fi recommended. Additional models fetch quietly in the background while your first game plays.
