Summarise a long PDF with AI
In short: Upload the PDF to an AI assistant that accepts files, ask for a plain-English summary with page references, then check the important parts against the original yourself.
Who is this for?
Anyone facing a long document: students with readings, people sorting through insurance or strata papers, volunteers reading meeting packs.
What do you need?
- The PDF on your computer or phone
- An AI assistant that lets you upload files, such as ChatGPT, Claude, Gemini or Gemini Notebook
- About ten quiet minutes to check the summary
How do you do it, step by step?
- Check what’s inside first. Skim the PDF. If it has private details (bank numbers, medical records, other people’s information), think twice before uploading it anywhere.
- Upload the file. Look for the paperclip or “+” button next to the message box and choose your PDF. Some free plans limit file size or how many files you can add.
- Ask for a plain summary. Paste the prompt below. Asking for page numbers makes it much easier to check the answer.
- Ask follow-up questions. Ask about the parts that matter to you, for example “What does it say about cancelling?” or “Explain section 4 simply.”
- Check the key points. Open the original at the page numbers given and read those parts yourself, especially dates, money and obligations.
What prompt can you copy?
Copy this, then replace everything in [square brackets] with your own details.
Please summarise the attached PDF in plain English for someone with no background in this topic. 1. Start with a 3-sentence overview. 2. Then list the main points as short dot points, with the page number for each. 3. Finish with anything I might need to act on (deadlines, costs, things I must do). If something isn’t clear in the document, say so rather than guessing.

Not sure? Our tool finder asks four quick questions and suggests a starting point.
What should you double-check?
- AI summaries can miss things or get them wrong, even with page numbers. Read the original for anything important.
- For legal, medical or money decisions, a summary is a starting point, not advice. Ask a qualified person.
- Scanned PDFs (photos of pages) may not be read well. If the summary seems thin, that may be why.
Common questions
Is it safe to upload a PDF to an AI tool?
It depends on what’s in it. Avoid uploading documents with passwords, bank or ID details, health records or other people’s private information. Check the tool’s privacy settings if you’re unsure.
Why do I need to check the summary?
AI tools can leave things out or state something wrongly with confidence. The page numbers help you check quickly.
What if the PDF is too big?
Try uploading one chapter or section at a time, or copy and paste the part you need.
