Details about AI Reports

Availability and types

Yes
Turnitin offers AI reports, and it categorizes AI-generated content into 2 types and shows different colors to highlight them:

  1. Light blue color to highlight the content, which is likely to be generated by AI.
  2. Purple color to highlight the content, which is likely to be generated by AI and then paraphrased by AI.

Yes
DrillBit offers AI reports, but it shows AI highlights in a single color. It doesn’t categorize AI generated content into categories.

Understanding AI report

It is easy to understand AI reports generated by Turnitin because they are highlighted in 2 different colors, and the report is available in the same formatting as the submitted file. So scholars can easily locate the part highlighted as AI-generated and paraphrase it.

It is very difficult to understand the AI reports of DrillBit because it disrupts the entire formatting of the submitted file. Sometimes it misses some characters, like it may show “Ankur’s” as “Ankurs” in AI report, so it is difficult to locate the text in the AI report and paraphrase it.

Accuracy of  AI Report (False Positives and False Negatives)

Turnitin does not show any % in its AI report if the AI-generated content is detected between 1% and 19%.
It acknowledges that its AI detection model is itself an AI, and thus mistakes are possible. It means it can mistakenly mark human-generated content as AI-generated and vice versa. So, it does not mention any specific number and does not highlight anything in such cases to avoid any negative consequences to scholars.

To know more about Turnitin AI reports, read our blog.

DrillBit claims that it can handle false positives and false negatives in a much better way in its AI detection. It means Drillbit believes that it accurately highlights AI-generated content. Thus it mentions specific percentages when AI is even below 10%.

Institutional Preferences and Global Adoption

Scholars cannot choose plagiarism detection software on their own. It is universities, colleges, and research journals that decide whether Turnitin or Drillbit should be used. Some institutions strictly require Turnitin reports for thesis and research paper submissions, making it the more globally recognized choice. Drillbit, while gaining popularity, is mostly preferred by institutions in India and South Asia due to its affordability and ease of use.

Conclusion: Which One Should You Use?

If your university or research journal mandates a specific plagiarism checker, you must follow their guidelines. Before using any software, confirm with your institution or supervisor whether Turnitin or Drillbit is required.

Most of the time, the decision is not in the hands of the scholar, as universities and journals set their own plagiarism policies. Always verify with your institution before selecting a plagiarism checker to ensure compliance with academic requirements.
