One useful question is a good start
See What You Can Ask
Choose a reading task. Preview an example, or copy the question for your own PDF.
The passage
The study compared rereading with self-testing. Self-testing helped students recall the material. The study involved one class, and long-term recall was not assessed.
Start with the source. Keep it close.
A question, then a clearer picture
What are the main findings and limitations?
Self-testing helped recall in this class. The study does not tell us whether the benefit lasts over time or applies to other groups.

Upload your PDF
Choose a research paper, report, contract, or study material. Drag it into the upload area or select it from your device. The upload limit shown on this page is 15MB; compress or split larger files first.
Ask a useful question
Start broad with “Summarize in five points,” or zoom in with “Explain this term simply.” Name the section and say what format you need: a short explanation, a checklist, or a list of key findings.
Follow up and check
Ask “How do these two sections differ?” or “What are the limitations?” Keep asking until the answer is useful. Check important facts, figures, and quoted wording against the original PDF before using them in your work.
