PRACTICAL GUIDE · CHOOSE BY USE CASE
AI tools for students: sources, study and writing support
Choose help for a specific study step: organizing source material, investigating a question, working through an explanation or editing your own draft. This selection gives you four starting points and the limits to check before making one part of your routine.
Questions to settle before choosing
What is the learning task?
Decide whether you need to understand a source, develop a question or improve a draft. Keep your course’s permitted-use rules in view when choosing a workflow.
Can you inspect the evidence?
Open cited sources and check whether they support the answer. Use explanations as material to examine, not as a substitute for reading or doing the work.
Which allowance could interrupt a study session?
Check file, research and chat limits separately. Save your own notes so that a usage limit does not take away the structure of your work.
A selection to explore
