Study From Your Own Material
NotebookLM lets you upload your lecture notes and textbooks, then ask questions answered from that material – not the open web. This keeps answers grounded in your syllabus.
Understand, Don’t Just Copy
ChatGPT and Claude are best used as tutors: ask them to explain a concept three ways, or to quiz you. Do not paste answers into assignments – use them to actually learn.
Research With Sources
Perplexity and Consensus give cited answers, so you can trust and verify. This matters for any submitted work where citations count.
Math and Memorization
Photomath and Symbolab show step-by-step solutions; Anki and Knowt handle spaced-repetition flashcards for long-term memory.
What NOT to Do
Do not rely on a single tool for everything, and always verify AI explanations against a trusted source. AI is a study partner, not a substitute for understanding.
