According to Chicago Style, you must credit ChatGPT when you reproduce its words within your own work, but unless you include a publicly available URL, that information should be put in the text or in a note. DO NOT CITE AI TOOLS IN YOUR BIBLIOGRAPHY OR REFERENCE LIST. Other AI-generated text can be cited similarly.
Author-Date Format for In-text Chicago Style Citation:
“(ChatGPT, March 7, 2023).”
If the prompt hasn’t been included in the text, it can be included in the note:
1. ChatGPT, response to “Explain how to make pizza dough from common household ingredients,” OpenAI, March 7, 2023.
Endnote or Footnote on AI tool:
1. Text generated by ChatGPT, OpenAI, March 7, 2023, https://chat.openai.com/chat.
Note: Chicago Style reccommends crediting ChatGPT and similar tools whenever you use the text that they generate in your own work. But for most types of writing, you can simply acknowledge the AI tool in your text.
