Numbers in parentheses refer to specific chapters and sections in The Chicago Manual (18th ed.)

Note: Content generated by artificial intelligence (AI) may not be considered an acceptable source for your course work. Be sure to evaluate content carefully and check with your instructor. Check our Academic Integrity guide for more information.

In Chicago Style, you need to credit tools such as ChatGPT or other generative AI whenever you use the text generated in your own work. This information should be in a footnote; it is not usually included in the bibliography. However, if, for some reason, it is included in a bibliography it should be cited under the name of the publisher or developer and not under the name of the tool. Include a publicly available URL (14.104).
