If you have lots of PDFs and notes then NotebookLM may be more useful.For research you can try Perplexity.If writing is your biggest problem then Grammarly can help.
For flashcards and revision you can try Quizlet.For math Wolfram Alpha is worth looking at.
And if you are learning programming then GitHub Copilot can be useful.There is no need to download every AI app you see online.
How Students Should Use AI
The best way to use AI is to make it help you learn.
For example don’t simply ask:
“Write my essay for me.”
Instead ask:
“Explain this topic in simple words and give me some questions to answer myself.”
You can also ask AI to quiz you after you study.
Another good idea is to explain something to the AI in your own words. Then ask it if your explanation is correct.This way you are still doing the thinking.AI can save time. But saving time doesn’t mean skipping the learning part.
You should also check the AI rules at your school or university. Some courses may allow AI for certain tasks while others may not. Academic rules are different between institutions. (purdueglobal.edu)
Common Mistakes Students Should Avoid
Copying AI answers
If you copy everything AI gives you then you may not actually learn anything.
Trusting every answer
AI can sometimes give wrong information. Check important facts and sources.
Using AI when it is not allowed
Always check your school’s or university’s rules before using AI for an assignment.
Using too many tools
You don’t need ten different AI apps. Start with one or two and see if they actually help.
Sharing private information
Be careful about uploading personal or sensitive information to AI tools.
