How to use AI for research and check what it finds

Before you start

AI apps look things up in two ways. Web search answers a question from a few cited pages. A research mode plans a search, reads many pages and writes a report. You pick the mode, and the price of picking wrong is time or usage limits.

Plans change quickly, so these are as of 5 November 2026. Research in Claude needs a paid plan and web search turned on. Deep Research in Gemini asks only that you are 18 or older and signed in, with daily limits. Researcher in Microsoft Copilot is for Microsoft 365 Premium and Pro subscribers, and for business users with a Copilot add-on license.

This lesson follows the help pages of Anthropic, Google and Microsoft. For ChatGPT, check OpenAI's help center for the search and research options your plan has. The habits below carry over.

Run a research job in five steps

The prompt below follows the five steps. It is our own sample. Replace the topic and keep the shape.

I manage a ten-person office and need to choose a shared password manager.

Research this. Use sources from the last two years, and prefer security reviews and official documentation over blog posts.

Give me:
1. A one-paragraph answer.
2. The three questions I should ask before choosing.
3. A list of sources, each with its link and one sentence on what it says.

Mark any claim you could not confirm in a source as "unconfirmed".

1. Write the question and what it is for. "Which password manager should a ten-person office use?" beats "password managers", because it says who decides and what they need.
2. Choose the mode. For one fact, use web search. For a decision, use the research mode. In Claude, click the + button at the bottom left of the chat and choose Research. In Gemini, choose Deep Research from the Add Files menu in the text box. In Microsoft Copilot, open Researcher under Agents.
3. Set the scope. Give a date range and the kinds of source to prefer. Microsoft says more specific prompts and a defined search scope give more relevant results, and Gemini lets you choose sources and edit its research plan before it starts.
4. Ask for a source list. Request the link and one sentence on what each source says, and tell the app to mark what it could not confirm.
5. Open the sources before you use the answer. Find the sentence behind every number you plan to quote.

Which tool does what

The same job has a different button in each app. The table lists where to find each mode and the one fact about it that surprises people.

None of these modes is two years old yet, and the model inside them keeps changing. Claude's Research help page now names a model released on 22 September 2026, and Research uses it whatever the chat is set to. A report you ran in the spring came from a different model than one you run today.

Check what it found

A research report reads as if an expert wrote it, and that is the risk. Google's page on sources describes the Sources button as a way to dig deeper, and it adds that not every response includes sources. Treat a link as a lead, not as proof. Anthropic's web search page says to cross-check cited sources and to rely on authoritative ones for critical decisions.

Checking one claim takes about a minute. Do it for every number and every name that your decision rests on.

When the app can read your email and files

Research tools can read more than the web. Claude's page says Research searches connected tools such as Gmail, Google Calendar and Google Docs, and that it uses them automatically, without asking for approval each time. Gemini lets you add Gmail and Drive as sources once Workspace is connected, and Microsoft's Researcher reads files, emails, meetings and chats you can access.

That reach is useful, and it has a cost: a research job can open material you did not think about. Connect only what the question needs, and run a question about the open web in a chat with no connectors.

What Anthropic posted when it launched Claude Research

Anthropic launched Research on X on 15 April 2025, and the same post announced a Google Workspace integration. The pitch fit in one line: Claude now brings together information from your work and the web.

Those two arrived together on purpose, and that is why you decide what to connect before a run starts. The help page today adds what the launch post left out. Connector tools run automatically during research, with no approval asked each time. A run started in the mobile app searches only the web and skips your connectors, and no error tells you so.

Pick the place to start by the question. Ask about the open web from a chat with no connectors. Ask about your own work from the web or the desktop app, where the connectors come along.

Common mistakes

• Taking a link as proof. A source can fail to support the sentence next to it, so open it.
• Asking a vague question. A report on "password managers" covers everything and decides nothing.
• Using a research mode for a one-line fact. Claude's page says research sessions use your limits faster, and Microsoft says Copilot Chat is better for quick answers.
• Trusting old pages. Ask for sources from a date range and look at the date on each one.
• Pasting the report into your document as the final text. Use it as notes, then write the conclusion yourself.

Try it yourself

• Pick a decision you face this month and write the question with its purpose.
• Run it with web search first, then with a research mode if your plan has one, and compare the two answers.
• Open the sources behind three claims and note which ones hold up.
• Ask the app: "What is the strongest argument against this answer?" and read what comes back.

Next: summarize documents

Research hands you pages to read. The next lesson, how to summarize a PDF with AI, covers the other half: you already have the document, and you need its main points without reading every page.
