What you give up either way
- Proprietary humanization engine and tuned training samples
- Multi-detector, sentence-level scoring across many paid detectors (Turnitin, GPTZero, Originality.ai, Copyleaks)

- Writing DNA / voice-matching and advanced fine-tuning sliders
- Priority support and enterprise features
