How to Use AI Responsibly as a Student
- Follow your school’s rules. Policies on AI vary. When in doubt, ask your teacher.
- Do not submit AI text as your own work. Use AI to learn, brainstorm and check, not to replace your effort.
- Verify facts. AI can make mistakes and invent sources. Check anything important in your textbook or a trusted source.
- Cite properly. If you use AI or a source, follow your school’s citation rules.
- Protect your privacy. Do not paste personal data, passwords or private information into AI tools.
- Test yourself. After using AI to understand something, close it and try to explain it in your own words.
