Frequently asked

Is using ChatGPT for homework cheating?
Depends on your university policy. Most allow AI for brainstorming, research, and editing - many forbid AI-generated final text submitted as your own. Read your specific course and program policies. When in doubt, ask the instructor.
Best free AI tool for studying?
NotebookLM. Upload up to 50 source PDFs (textbook chapters, lecture notes, research papers), it synthesizes them into structured Q&A and audio overviews. Genuinely useful for exam prep on dense material.
Photomath - does it actually teach math or just give answers?
It shows step-by-step solutions which is genuinely educational if you read each step. Used as a "answer machine" it short-circuits learning. Treat it like a tutor: do the problem, then check.
Can I detect AI-written text and is it worth worrying about?
Most "AI detectors" produce high false-positive rates and are unreliable. Your professor likely cannot prove text is AI-written, but they often can tell when writing does not match your usual style. The risk is reputational, not technical.
Should I pay for ChatGPT Plus as a student?
Only if free-tier rate limits actually slow you down (heavy daily user). For most students, free ChatGPT plus free Claude alternates handles 95% of need. Spend money on Notion AI, Anki upgrades, or coffee instead.
