Important: Writing analysis in this static application is local and heuristic-based. AI detection uses a browser-loaded ONNX classifier (see Settings) and should be treated as a rough estimate, not a verdict — every model tested here, including the default, has confirmed blind spots and biases. See each model's description in Settings before trusting a specific number.
