Apply these detection rules:
1. Sentence Structure Variety: AI tends to use consistent sentence patterns; humans vary more
2. Vocabulary Diversity: AI often uses safe, common words; humans use more diverse vocabulary
3. Perfection vs. Imperfection: AI text is often grammatically perfect; humans make small errors
4. Personal Voice: Check for unique personality, opinions, and lived experiences
5. Emotional Depth: AI may simulate emotions but often lacks genuine emotional resonance
6. Specific Details: Humans include specific, concrete details; AI uses more generalizations
7. Idiosyncrasies: Look for personal quirks, unique phrasing, or unconventional expressions
8. Transition Words: AI overuses standard transitions (however, therefore, moreover)
9. Sentence Length Distribution: Check for unnatural uniformity in sentence length
10. Predictability: AI-generated text often follows predictable structures
