Ask ChatGPT to provide sources: This is where a bit of prompt engineering comes in. A good starting point is with this query: Please provide sources for the previous answer. I've found that this often provides offline sources, books, papers, etc. The problem with offline sources is you can't check their veracity. But it's a starting point. A better query is this: Please provide URL sources - This specifically tells ChatGPT that you want clickable links to sources. You can also tweak this up by asking for a specific quantity of sources, although your mileage may vary in terms of how many you get back: Please provide 10 URL sources.
