How to Use AI Ethically as a Student
- Use AI as a tutor, not a ghostwriter — Learn from AI, don’t submit AI work as your own
- Always cite your sources — AI can help find sources, but you need to verify and cite them
- Check your school’s AI policy — Many schools have specific guidelines
- Develop your own voice — Use AI to improve your writing, not replace it
