The Chicago format

Pattern

Response to “prompt,” Tool, Company, Month Day, Year.

  • Notes only for a chat others cannot open.
  • With a public share link, add the URL and a bibliography entry under the company.
  • In your sentence, you can name the prompt instead and keep the note short: Text generated by ChatGPT, OpenAI, March 8, 2023.

A real example

Footnote (no bibliography entry)

Response to “Describe the symbolism of the green light in the book The Great Gatsby by F. Scott Fitzgerald,” ChatGPT, OpenAI, March 8, 2023.

When details are missing

  • No prompt in the note: say what you asked in your sentence.
  • Edited AI text: say so in the note: “edited for style.”

Common mistakes

  1. A bibliography entry for a private chat. Only shareable output is listed.
