Ethical Considerations
While AI research tools are incredibly useful, be aware of limitations:
- AI Hallucinations: Always verify AI-summarized claims against original papers
- Citation Accuracy: AI sometimes misattributes findings—double-check citations
- Bias in Selection: AI may favor certain papers—ensure comprehensive coverage
