AGENTIC CHESS vs Chess Coach

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.
