Why are the AI detection indicators showing abnormal results？
1. Gray with no percentage displayed (–):
The AI writing detection indicator is unable to process this submission. This can be due to one, or several, of the following reasons:
① The submission was made before the release of Turnitin’s AI writing detection capabilities（April 5, 2023). The only way to see the AI writing detection indicator/report on historical submissions is to resubmit them.
② The submission does not meet the file requirements needed to successfully process it for AI writing detection. In order for a submission to generate an AI writing report and percentage, the submission needs to meet the following requirements:
- File size must be less than 100 MB
- File must have at least 300 words of prose text in a long-form writing format
- Files must not exceed 15,000 words
- File must be written in English
- Accepted file types: .docx, .pdf, .txt, .rtf
2. Red with Error ( ! ):
