What You'll Learn
How to use AI to extract the key insights from any long document — a research paper, annual report, legal contract, news article, or book chapter — in minutes rather than hours.
Why This Matters
We are all drowning in documents. Most professionals receive more reports, papers, and articles than they could ever fully read. AI can read a 50-page document in seconds and give you a crisp summary that tells you whether the full document is worth your time — and captures the essential points if it is not.
Step-by-Step Guide
Step 1: Choose the right tool for your document
- ChatGPT or Claude — paste text directly (up to ~100,000 words for Claude, ~20,000 for ChatGPT)
- NotebookLM — upload PDFs and ask questions about them; best for long research documents
- Perplexity AI — paste a URL and ask for a summary of a web article or paper
Step 2: Paste or upload your document
For pasted text, start with:
Here is a document I need you to summarise. Please read it carefully before responding.
[paste full document text]
---
Now please provide:
1. A 3-sentence executive summary
2. The 5 most important points or findings
3. Any key recommendations or conclusions
4. One thing that surprised you or stands out as particularly significant
Step 3: Ask follow-up questions
Once you have the summary, drill deeper:
Based on this document:
- What evidence is given for [specific claim]?
- Are there any limitations or caveats the author mentions?
- How does this compare to [other thing you know about]?
- What is the single most actionable takeaway for someone in [your role]?
Step 4: Use NotebookLM for multi-document research
Upload several related documents and ask cross-cutting questions:
I've uploaded three reports on [topic]. What are the points all three agree on? Where do they differ, and why?
Tips for Better Results
- Specify your role. "Summarise this for a marketing manager with no technical background" produces a very different output than "summarise this for a data scientist."
- Ask for the counter-arguments. "What are the weakest points in this argument, or what does the author acknowledge they don't know?"
- Use Claude for very long documents. Claude can handle much longer inputs than most AI tools — ideal for lengthy reports or book chapters.
Tools That Work Best for This
- NotebookLM — the best tool for PDFs and research documents. Upload your sources and have a full conversation with the document.
- Claude — handles the longest text inputs of any general-purpose AI, making it ideal for lengthy contracts, reports, or academic papers.
- Perplexity AI — excellent for summarising web articles and online content directly from a URL.
