Could you build this?
Partial The UI and chess game loop are vibe-codeable, but bundling and optimizing on-device local LLMs (Qwen/Gemma) alongside native Stockfish integration across Android, Windows, and Linux requires non-trivial cross-platform native runtime tuning.
What it would actually take: The architecture typically uses Flutter or Tauri/C++ paired with llama.cpp or ONNX Runtime bindings for on-device LLM inference, alongside a UCI (Universal Chess Interface) process manager to communicate with Stockfish compiled for multiple architectures (ARM64, x86_64). The difficult engineering parts include memory management and quantized model execution within strict mobile thermal/RAM constraints, cross-compiling native C++ binaries across three different OS environments, and performing low-latency vector search locally across a large PGN database.
