❓ FAQ
Q: Is it cheating to use AI for homework? A: Depends on your school's policy. Using AI to understand concepts is generally fine; submitting AI-generated work as your own is not.
Q: Can professors detect AI writing? A: AI detectors exist but are unreliable. The bigger risk is submitting work that doesn't match your usual writing style.
