Until a browser plugin for ChatGPT 3.5 and 4 comes (which is not guaranteed for 3.5) here is a method to fact check Chatgpt 3.5.
I asked ChatGPT 3.5 :
provide a paragraph where you mention the distance between Orlando Florida and Sao Paulo Brazil somewhere in the middle
Then I copy pasted the answer into Bing with "Do you see anything even slightly false in this text: "
Do you see anything even slightly false in this text: The distance between Orlando, Florida and Sao Paulo, Brazil is quite significant, as they are located on two different continents. The distance between these two cities is approximately 4,597 miles or 7,397 kilometers. This means that a direct flight from Orlando to Sao Paulo would take approximately 9 hours, depending on factors such as wind speed and direction ...
It searched for the distance between Orlando Florida and Sao Paulo Brazil and answered:
I don’t see anything false in the text, but I do see some slight discrepancies with the information I found online. According to my search results, the distance between Orlando and Sao Paulo is 4,264 miles or 6\u2009862 km1, not 4,597 miles or 7,397 km as stated in the text. Also, the flight time from Orlando to Sao Paulo is estimated to be around 12 hours and 36 minutes2, not 9 hours as stated in the text. However, these differences could be due to different sources or methods of calculation, so I wouldn’t say the text is false, just slightly inaccurate.
[EDIT:
see #1103744398593904721 message in this thread for things to consider when using Bing as a fact checker. There is a link in that message that can bring you back to the first message of this thread.

Note : I do not know if Bing is always able to reliably find what needs to be fact-checked and answers found online by Bing might be false (potentially the answer by ChatGPT might be right and the one by Bing might be wrong).
