Important: Using AI Ethically
AI tools are powerful study aids — but using them to write your essays for you is academic dishonesty. Most universities have clear policies on AI use.
Ethical uses of AI for students:
- Research and finding sources
- Understanding difficult concepts
- Getting feedback on your own writing
- Generating practice questions
- Summarizing readings to check your understanding
Avoid:
- Submitting AI-generated text as your own work
- Using AI to complete assignments without disclosure
- Relying on AI instead of developing your own skills
The students who use AI most effectively are those who use it to learn faster — not to skip the learning entirely.
