How to Cite ChatGPT in APA, MLA, and Chicago (2026)

By the Chatgbot Team · Published July 22, 2026

If you used ChatGPT while writing a paper, you may need to cite it. The good news is that the rules are far more settled than they were a few years ago. APA, MLA, and Chicago have all published guidance on citing AI tools, and most universities now point to one of these three formats in their academic integrity policies.

This guide shows you how to cite ChatGPT in all three styles, with worked examples you can copy and adapt. It also covers when citation is required at all, how to cite assistants like Claude and Gemini, and how to disclose AI help properly.

First, check whether you can use AI at all

Before you worry about citation format, check the policy that governs your work. A citation only matters if AI use is permitted in the first place.

• Course syllabus or assignment brief. Individual instructors set their own rules, which range from a full ban to open use with disclosure. The syllabus overrides any general advice you read online, including this guide.
• University academic integrity policy. Many schools now have a campus-wide AI policy that applies when a syllabus is silent.
• Journal or publisher guidelines. Most journals refuse to list AI as an author but allow disclosed use in a methods or acknowledgments section.

If the policy bans AI use, citing ChatGPT does not make the use acceptable. When in doubt, ask your instructor or editor before you submit, not after.

How to cite ChatGPT in APA 7

APA treats ChatGPT output as the product of an algorithm, so the reference lists OpenAI as the author. Because a chat is not retrievable by your reader, APA asks you to describe the prompt in your text and, where allowed, include the full transcript in an appendix.

Reference list entry:

OpenAI. (2026). ChatGPT (GPT-5.6, July 2026 version) [Large language model]. https://chatgpt.com/

In-text citation: (OpenAI, 2026), or narratively, OpenAI (2026).

Worked example in a sentence: When prompted to summarize competing explanations for the Bronze Age collapse, ChatGPT listed four candidate causes, including climate stress (OpenAI, 2026).

Key parts of the cite ChatGPT APA format: author (OpenAI), year of the version used, the model name in italics, the version in parentheses, the bracketed description [Large language model], and the URL.

How to cite ChatGPT in MLA 9

MLA uses its template of core elements and treats the prompt as the title of the source. You shorten the prompt if it is long, place it in quotation marks, and add the word prompt after it. ChatGPT is the container, OpenAI is the publisher, and the date is the day of the conversation.

Works Cited entry:

"Describe the symbolism of the green light in The Great Gatsby" prompt. ChatGPT, GPT-5.6, OpenAI, 12 July 2026, chatgpt.com.

In-text citation: a shortened version of the title, for example ("Describe the symbolism").

The cite ChatGPT MLA convention feels unusual at first because the author slot stays empty. MLA reasons that the AI is not an author, so the prompt, which you wrote, becomes the identifying element.

How to cite ChatGPT in Chicago style

Chicago (notes and bibliography style) recommends citing ChatGPT in a numbered footnote or endnote, and generally not in the bibliography, because the conversation is not recoverable by readers.

Footnote example:

1. ChatGPT, response to "Explain the main causes of the 1929 stock market crash," OpenAI, July 12, 2026.

If you edited the output before using it, Chicago suggests saying so in the note, for example by adding "edited for style" at the end. If you have a shareable link to the conversation, you can append it, and in that case a bibliography entry becomes reasonable.

Citing Claude, Gemini, and other AI assistants

All three styles extend to other assistants by analogy. Swap the company for the author or publisher slot and the product for the model name, then keep everything else the same.

• Claude (APA): Anthropic. (2026). Claude (Opus, July 2026 version) [Large language model]. https://claude.ai/
• Gemini (APA): Google. (2026). Gemini (July 2026 version) [Large language model]. https://gemini.google.com/
• Claude (MLA): "Your prompt here" prompt. Claude, Anthropic, 12 July 2026, claude.ai.

The same logic covers Grok (xAI), DeepSeek, and Perplexity. If you are comparing answers across models for a project, our guide to the best AI for students breaks down where each assistant is strongest.

How to describe AI use in a methods or acknowledgments section

Citations cover quoted or paraphrased output. Many policies also ask for a broader disclosure statement describing how you used AI overall. Keep it factual and specific.

A methods-style sentence might read: ChatGPT (GPT-5.6, OpenAI) was used to generate an initial list of search terms and to check the clarity of the abstract; all analysis and final wording are the authors' own.

An acknowledgment version: The author used ChatGPT (OpenAI) to suggest structural improvements to an early draft. The author reviewed and edited all content and takes full responsibility for it.

State which tool and version you used, what tasks it performed, and confirm that you verified the output and take responsibility for the final text.

Keep records and protect your academic integrity

Because AI conversations are hard for others to retrieve, your records are your evidence. Build a simple habit for any graded or published work.

1. Save a shareable link to the conversation when the tool offers one, and note the date.
2. Take screenshots of key exchanges in case the link breaks or the chat is deleted.
3. Keep your drafts. Version history in your document shows how your own writing evolved.

There is also a line citation cannot fix. Using AI to understand a concept, test your reasoning, or get feedback is study. Submitting uncited AI generated text as your own work is plagiarism under most policies, even when detection is uncertain. Our guide to the best AI for homework explains how to keep AI on the right side of that line, and if you write code, note that some instructors run submissions through an AI code detector.

Quick reference: the three formats at a glance

Whichever style you use, describe the prompt honestly and check whether your instructor wants the full transcript attached. For deeper workflows, see our roundup of the best AI for research.

Frequently asked questions

Do I need to cite ChatGPT if I only used it for brainstorming?

Usually not in the reference list, but many policies still expect a disclosure note. If no ideas or wording from the chat appear in your text, a short acknowledgment is typically enough. When the policy is unclear, disclose anyway. It costs one sentence and removes all risk.

Can I include a link to my ChatGPT conversation in the citation?

Yes, and it strengthens the citation. ChatGPT can generate a shareable conversation link, which you can add to an APA reference, an MLA entry, or a Chicago note. Save a screenshot too, since shared links can stop working if the chat is deleted.

How do I cite Claude or Gemini instead of ChatGPT?

Use the same structure and swap the names. In APA, Anthropic or Google becomes the author and Claude or Gemini becomes the model name. In MLA and Chicago, the company takes the publisher slot. Everything else, including dates, versions, and prompt descriptions, stays the same.

Is citing ChatGPT enough to avoid plagiarism?

Only if AI use is allowed for that assignment. A citation documents your source, but it does not override a ban, and it does not cover work where the assignment required your own original writing. Check the syllabus or journal policy first, then cite and disclose.

Cite any model from one place with Chatgbot

If your coursework has you switching between assistants, keeping citations straight across separate apps gets messy fast. Chatgbot puts GPT-5.6, Claude, Gemini, Grok, and DeepSeek in one app, so you can compare answers side by side, keep every conversation in one history, and record the model and date you need for a clean citation.
