Chicago Example for Gemini
Chicago does not give Gemini an entry in the bibliography — it is cited in a note only. Here is that note, written by hand and checked against the official Chicago guidance:
1. Gemini 2.5 Flash, response to “I’d like a list of grammar topics that a student should understand by the time they graduate from high school,” Google, May 22, 2025, https://g.co/gemini/share/a1306ce12929.
Chicago In-Text Citation
Use one of these formats when referencing this source within your paper:
Parenthetical
Footnote: 1. Gemini 2.5 Flash, response to “I’d like a list of grammar topics that a student should understand by the time they graduate from high school,” Google, May 22, 2025, https://g.co/gemini/share/a1306ce12929.
Narrative
Shortened note: 2. Gemini 2.5 Flash, response to “list of grammar topics.”
Key Chicago Formatting Rules
- Credit Gemini in the text or a numbered note; CMOS 18 §14.112 does not usually include chatbot conversations in the bibliography.
- Put the tool and model (Gemini 2.5 Flash) first in the note and Google as the publisher.
- Include the prompt in the note unless your sentence already states it, as in “The following overview was generated by Gemini.”
- Add the g.co/gemini/share link only when it opens for someone signed out of your Google account; otherwise stop after the date.
- Cite the linked web page, not Gemini, for anything you found through a Google AI Overview.
Step-by-Step Guide
- Gather source information: Collect the author name, title, publication date, and URL or DOI for your Gemini.
- Format the reference: Arrange the elements following the Chicago (18th edition) template shown above.
- Create the in-text citation: Add a parenthetical or narrative citation in your paper where you reference this source.
- Add to your bibliography: Include the full formatted citation at the end of your paper.
- Double-check formatting: Verify italics, punctuation, capitalization, and hanging indents match Chicago requirements.
Evidence and review notes
Worked examples on this page are written by hand from the style's own published guidance and checked against it, because the general CSL styles do not encode this source's rules. Editorial guidance and sources in this section were reviewed on 2026-08-14.
Metadata to collect
- the company that built the tool (Google)
- the Gemini model shown, such as Gemini 2.5 Flash
- the date of the conversation
- the chat title in your Gemini history
- the exact prompt you typed
- the public g.co/gemini/share link
Common metadata traps
- A Google AI Overview at the top of Search results is not a Gemini chat; MLA says AI Overviews are search results, not a work, so click through and cite the page it links.
- The gemini.google.com/app/ address in your browser bar is private; readers can open only the link the Share button creates, which begins g.co/gemini/share.
- Gemini used inside Gmail, Docs, or Slides is AI built into ordinary software, which APA’s Part 2 post treats like spell-check: usually a disclosure, not a reference.
