When you open a Similarity Report, the AI writing indicator is located on the side panel.
If the AI indicator is gray with no percentage displayed (--) and upon hovering over the indicator the message AI writing detection unavailable appears, this means that AI Writing Detection cannot be processed for the submission.
This may be because:
- The submission was made before the release of Turnitin's AI writing detection capabilities on the 4th of April 2023
- The submission does not meet the file requirements needed to successfully process it for AI Writing Detection
The only way to obtain the AI writing report on historical submissions is to resubmit them. If the file does not meet our supported file requirements, the file will need to be updated to meet our requirements and resubmitted.
Further guidance on our supported file requirements and the AI writing indicator states can be found within our AI Writing Detection help guides.
