1. Upload the file
Click the paperclip in ChatGPT and attach the PDF (works on the paid tiers; large files may need splitting).
2. Ask for structure, not “a summary”
Summarize this PDF as:
- 3-sentence overview
- the 5 most important points (bullets)
- any numbers, dates, or decisions
- 2 open questions it leaves unanswered
3. Drill in
Expand point 3 with the supporting details from the document only.
Telling it “from the document only” reduces made-up details. For very long PDFs, summarize in chunks, then summarize the summaries.
