Ethical Guidelines for Using AI Tools in Academic Writing
- Always check your university's AI use policy before using any AI tool in assessed work
- Use AI for assistance (editing, structure suggestions, literature search) — not for generating original arguments or ideas
- Disclose AI tool use in your methods or acknowledgements where required by your institution or journal
- Never use AI to fabricate citations, data, or research findings
- Verify all AI-suggested information against primary sources — AI tools can hallucinate
