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
- File must not exceed 30,000 words
- FIle must be written in a supported language: English, Spanish, Japanese
- Accepted file types: .docx, .pdf, .txt, .rtf
Best practice: When using Turnitin's AI writing detection for assignments, it's best practice to have all students submit their work in the same file format (e.g., all .docx or all .pdf). This helps maintain uniformity in how submissions are processed.
