Research and summaries
Get up to speed on any topic, and summarise long material reliably.
Research used to mean ten browser tabs. Now you can get a solid overview in minutes, if you use the right tool for each part.
Three kinds of research
- "Explain this to me": a general chatbot is perfect. "Explain how VAT works for a small online shop in the UAE, in plain language."
- "What's true right now?": use a tool that searches and cites, like Perplexity. Prices, regulations and news change.
- "What do these documents say?": upload them to NotebookLM or attach them to your chatbot, and ask questions about those documents.
Summaries you can trust
Ask for a structure, not just "summarise":
Summarise this report for a busy manager: 1) the three main findings, 2) what we should do, 3) anything uncertain or missing. Quote the exact sentence for each finding.
Asking for quotes makes it easy to check the summary against the source.
Long material
For long PDFs, meeting transcripts or many files, NotebookLM keeps answers tied to your sources with clickable citations. Ask follow-ups like "Where do the authors disagree?"
Know the limits
- Chatbots without web search may not know recent changes.
- Summaries can drop important caveats. For decisions, read the key section yourself.
- Never paste confidential documents into tools your workplace hasn't approved.
Key takeaways
- Match the tool to the question: explain (chatbot), current facts (Perplexity), your documents (NotebookLM).
- Ask for structured summaries with quotes you can check.
- Read the key section yourself before deciding.
