The best workflow (works for free)

  1. 1) Summarize the whole PDF first
    Get a top-level overview: what it’s about, key conclusions, and any deadlines.
  2. 2) Ask one targeted question
    Example: “What are the key risks, dates, and action items?”
  3. 3) Re-run on the most important section (optional)
    For long PDFs, extract the executive summary or conclusions and summarize that section for better signal.
Best one-line prompt to use

Are AI summaries accurate?

They’re usually very good for extracting main themes and key points, but you should double-check critical details (numbers, dates, legal clauses).
