AI Writing Detection: Tools

  • Turnitin. The AI detection functionality was released in early April 2023. Turnitin claims their product to be 98% effective at catching AI-generated text. It is available automatically for all assignments where Turnitin is enabled.
    • For more information about this functionality, see Turnitin’s release statement.
    • Note that this functionality was trained on GPT-3.5 model. It may be less good at catching submissions generated by the more recent GPT-4 model. GPT-4 is only available with paid subscription, but some students may have it.
  • GPTZero
  • ZeroGPT
  • OpenAI’s AI Text Classifier

It is important to keep in mind that currently no software will detect AI-generated text with 100% certainty. AI-generated texts may be classified as human, and the other way around. Carefully review the findings of AI-detecting software, and consider the student’s writing history and the context of the assignment before making a decision.
