Key Risks for Universities
Compromised academic integrity
False accusations from inaccurate detectors
AI-paraphrased content bypassing weak systems
Students using rewriting tools to avoid detection
Difficulty verifying multilingual assignments
What Universities Should Prioritize
A good academic AI detector must have:
