Key Points to Remember
- Accuracy is not perfect: Many detectors struggle with paraphrased or refined text.

- Best used as support tools: These should guide human judgment, not replace it.
- Different tools suit different needs: Free tools are good for quick checks; enterprise tools offer depth, reports, and reliability.
