How to Check Essay Content for AI
What to watch for when checking essay content for AI:
- A generic thesis with no personal specifics, examples, or voice.
- Even paragraph structure wrapped around a thin or repetitive argument.
- Vocabulary or tone that jumps above the student's usual writing.
- Smooth transitions with no digressions, false starts, or personality.
- Citations that are vague, mismatched, or that do not quite support the claim.
