If you are using a model that links to its sources (like Copilot, Perplexity, or Gemini), follow the links and read the original pages. Make sure the AI-generated summary aligns with the content of the page it came from. And make sure the page content is relevant to the task you asked the model to do.

If you are using the free version of ChatGPT (without links to sources), you will want to do a quick web search to find out if what it’s saying is true. Look for more than one source to verify the information. Wikipedia can be helpful as can mainstream news sites that employ fact-checkers.

Because the free version of ChatGPT doesn’t have an understanding of facts (unless you click the "search" button), it’s often better to use a model that links to its sources, like Perplexity or Copilot. This makes it easier to fact-check.

Note: Free accounts on ChatGPT can now search the web and will do so automatically for some queries. But to make sure that it searches for your query, click the "search" icon so that it turns blue before you type your query.
