Based on the platform you are using, detection technology, and coverage of the source databases used, the results of plagiarism checking will often differ.
Each platform scans for different sources and applies different algorithms using different detection technologies. As a result, this can lead to differences in similarity scores and reports generated from results.
Key reasons results may differ include:
- Database Coverage: Institutional tools may cover both private and institutional databases that may not be available on another tool.
- Detection Methods: Tools may differ in how they detect paraphrased or AI-content.
- Configuration Settings: Each university may use a different threshold setting when configuring the system.
- Update Frequency: Source databases may be updated at different intervals
Important Caveat: Pre-checking work with a reliable tool can reduce risk, but results may still vary based on institutional systems.
