Step-by-Step Checklist: How Students Should Use AI Responsibly
While artificial intelligence offers incredible advantages, it must be approached with ethical boundaries and academic honesty. Follow this step-by-step checklist to ensure responsible usage:

- Preserve Your Unique Voice: Ensure that your final submitted work reflects your own critical thinking and personal writing style.
- Review Institutional Guidelines: Always consult your school or university's specific honor code and AI usage policies before incorporating these tools into graded submissions. For official academic standards, refer to guidelines published by organizations like APA Style.
