Key Pointers
- All three major style guides (APA, MLA, Chicago) have now published guidance on how to cite ChatGPT and other AI-generated content. If your professor allows AI use, citing it correctly is the difference between disclosed use and undisclosed use.
- APA treats ChatGPT output as personal communication or as software, depending on context. The APA Style blog now has an official ChatGPT citation format.
- MLA treats AI-generated content as a source and requires you to disclose the prompt, the tool, the version, and the date accessed.
- Chicago Manual of Style recommends footnote citations for AI-generated content, with the prompt included so a reader could theoretically reproduce the output.
- Most professors will accept a properly cited AI source when your class policy allows AI use. The problem is undisclosed AI use, not cited AI use.
The Short Version
If your class allows AI use, you have to cite ChatGPT (or Claude, Gemini, or any other AI tool) as a source in your paper. APA, MLA, and Chicago now all have official formats for citing AI content. The APA format treats ChatGPT as software with a specific author, date, title, and URL. MLA treats it as a source with prompt disclosure. Chicago prefers footnote citations that include the prompt. In every case, the underlying rule is the same: disclose that AI was used, when, for what, and give enough detail that a reader understands your process.
Why AI citation matters in 2026
Picture a Sunday night. You’re finishing a research paper and your professor’s syllabus said AI use is permitted for brainstorming and outlining, but any use has to be disclosed. You used ChatGPT to generate three thesis statement ideas at the start of the project. Now you’re at the citations section, and you have no idea how to cite it. The APA guide you were taught in undergrad doesn’t cover this.
That’s the situation every student and researcher is in right now. Style guides that were built for print sources are still catching up to how citations should work when the “source” is a large language model. The good news is that all three of the major style guides (APA, MLA, Chicago) have now published official guidance on citing ChatGPT and other AI-generated content. This post walks through what each one requires, with examples.
The bigger point behind the mechanics: citing AI use is what protects you. Undisclosed AI use is what gets flagged. Every AI citation format below is a way of disclosing the use in the format your assignment requires.
How to cite ChatGPT in APA style
APA released official guidance on citing ChatGPT in early 2023 and has updated it since. Per the APA Style blog on how to cite ChatGPT, the current APA format treats ChatGPT (and comparable AI tools) as software. The citation includes the author (OpenAI or the parent company), the year, the tool name and version, and a URL.
Reference list format:
OpenAI. (2024). ChatGPT (November 20 version) [Large language model]. https://chat.openai.com
In-text citation:
(OpenAI, 2024)
Full example with the prompt in the text:
When prompted with “Explain the causes of the 1929 stock market crash in three sentences,” ChatGPT produced a summary listing over-leveraging, weak banking regulation, and speculative buying (OpenAI, 2024).
APA recommends that you describe the prompt in your writing (either in the text of the paper or in an appendix), so the reader can reproduce your process. The reference list entry cites the tool, and the in-text citation references the tool by author and year.
For a full walkthrough of APA formatting more broadly, the complete guide to APA citations covers the rest of the style, which is worth reading alongside the AI-specific format if you’re writing a paper with many citations.
How to cite AI in MLA style
MLA Style updated its guidance in 2023 to cover generative AI content specifically. Per MLA Style on citing generative AI, MLA treats AI-generated content as a source and requires you to include the prompt, the tool, the version, and the access date.
Works Cited entry format:
“Explain the causes of the 1929 stock market crash in three sentences” prompt. ChatGPT, 20 Nov. version, OpenAI, 21 Nov. 2024, chat.openai.com.
In-text citation:
(“Explain the causes” prompt)
MLA’s format is more prompt-forward than APA’s. The Works Cited entry actually opens with the prompt itself as if it were the title, which reflects MLA’s position that the specific prompt is essential to reproducing the output. If you’re citing multiple ChatGPT outputs in the same paper, each one gets its own Works Cited entry with its own prompt.
MLA also recommends that you note the tool doesn’t produce reliable factual content, and any specific facts, statistics, or quotations pulled from AI output need to be verified against a primary source before you cite them.
How to cite ChatGPT in Chicago style
Chicago Manual of Style published its guidance on citing generative AI in late 2023. Per the Chicago Manual of Style Q&A on citing generative AI, Chicago prefers footnote citations for AI-generated content rather than in-text parenthetical citations, and the footnote should include the prompt.
Note format (first citation):
- ChatGPT, response to “Explain the causes of the 1929 stock market crash in three sentences,” OpenAI, November 21, 2024.
Note format (subsequent citations):
- ChatGPT, response to “What was the role of the Federal Reserve in the 1929 crash?” OpenAI, November 21, 2024.
Bibliography entry:
Chicago typically does not include AI-generated content in the bibliography, since each output is a unique conversation rather than a repeatable published source. Chicago instead recommends including AI use in the footnote where it’s referenced.
For the wider Chicago citation format, the what are Chicago style citations breakdown covers the rest of the style, which is worth reading if you’re using Chicago for the first time.
Citing AI-generated content that isn’t ChatGPT
The same three formats extend to other AI tools. Substitute the tool name and the parent company:
- Google Gemini: Google (as author), Gemini (with version)
- Anthropic Claude: Anthropic (as author), Claude (with version)
- Microsoft Copilot: Microsoft (as author), Copilot (with version)
- Meta Llama: Meta (as author), Llama (with version)
For less-known or open-source tools, cite the model name and the developer. If you’re using a wrapper tool (like a specific plagiarism checker’s built-in AI writer), cite the wrapper company and note the underlying model where possible.
Where AI citation gets tricky
Three situations that don’t have clean rules yet.
When AI-generated content is edited by you. If ChatGPT produced a draft and you rewrote most of it, is it still an AI source? The safer path is to disclose the AI use in an author’s note or methodology section, then cite it in the format above only if specific phrases or ideas came directly from the AI output.
When the AI cited its own sources. ChatGPT and other tools sometimes cite books or papers in their responses. Those citations are often hallucinated (invented but plausible-looking). Never trust AI-generated citations without verifying each one against the actual source. If a source is real and you’re using it in your paper, cite the actual source, not the AI that mentioned it.
When your class policy says “no AI at all.” Then citation doesn’t help. In classes where AI use is prohibited, using it and citing it doesn’t turn the violation into a permitted use. Read your syllabus first, cite second.
Generate citations instantly with a citation tool
Formatting AI citations by hand is possible but tedious, especially when you’re citing multiple outputs across a long paper. A dedicated citation tool handles the formatting automatically and keeps you aligned with the current version of each style guide (which matters, because APA, MLA, and Chicago update their AI guidance as usage patterns change).

For a wider view of the citation tool category, the roundup on best plagiarism checker with AI detection covers tools that combine citation support with plagiarism and AI detection in one platform, which is what most academic workflows actually need.
The disclosure step that goes beyond citation
Even with the right citation format, most 2026 syllabi now require a separate AI disclosure statement at the end of the paper or in a methodology note. Something like:
“AI use disclosure: I used ChatGPT to generate three potential thesis statement ideas at the start of the project (November 5, 2024). No AI-generated text appears in the final paper. All research, analysis, and drafting is my own.”
That statement isn’t a citation. It’s a summary of your AI workflow, and it lives alongside your citations rather than replacing them. If your class policy requires disclosure, include both the citation (where AI content appears in the paper) and the disclosure statement (as a summary of overall AI use).
Common mistakes when citing AI
Four patterns that come up regularly in flagged student papers.
Citing AI-generated citations as if they were real sources. AI tools invent citations. Any citation that came from ChatGPT should be verified against the actual source before you include it in your paper. Otherwise you’re citing something that doesn’t exist.
Missing the version number or date. AI tools update constantly. The version and date matter because the same prompt on the same tool a month later might produce different output. Include both in every AI citation.
Skipping the prompt. MLA and Chicago both require the prompt in the citation. APA recommends including the prompt in the text of the paper. Skipping it makes your citation incomplete and harder for a reader to reproduce.
Assuming citation is enough when the class prohibits AI. Citation doesn’t override a class-level prohibition. If your syllabus says no AI, no amount of correct citation makes AI use permitted.
Wrap-up
Citing ChatGPT and AI-generated content isn’t complicated once you know each style’s format. APA treats it as software with author, date, tool, and URL. MLA treats it as a source with the prompt included. Chicago uses footnotes with the prompt disclosed. In every case, the underlying rule is the same: disclose your AI use so the reader knows what came from you and what came from the tool.
The rule that matters most: cite what you used, verify what the AI cited, and disclose your AI workflow when your class requires it. Do those three things and the citations side of AI use stops being a risk.

FAQs
How do you cite ChatGPT in APA?
APA treats ChatGPT as software. The reference list entry lists OpenAI as the author, the year, the tool name and version, and the URL. Format: OpenAI. (2024). ChatGPT (November 20 version) [Large language model]. https://chat.openai.com. The in-text citation is (OpenAI, 2024). APA also recommends describing the prompt in the text of your paper or in an appendix so the reader can reproduce your process.
- Treat ChatGPT as software
- List OpenAI as author, include version and date
- Describe the prompt in your text or appendix
How do you cite AI in MLA style?
MLA specifies that AI-generated content should be considered a source, and it is important to provide a prompt in the Works Cited section. Here is how to do it: “Prompt” prompt. ChatGPT, [version], OpenAI, [date of access], chat.openai.com.
MLA is considered more prompt-oriented than APA, and it sees AI outputs as individual sources with own reference list entries. Each time you have used ChatGPT multiple times in a text, make separate reference list entries for all of its outputs.
- Prompt must be included in the Works cited entry
- Each AI output should be regarded as individual source
- Don’t forget to add tool, version, and date of access
How do you cite ChatGPT in Chicago style?
According to Chicago style, footnotes should be used when referencing AI content. Footnotes must contain the name of the tool, the prompt, its parent company, and the date of use. Thus, the format should be: “ChatGPT, response to prompt, OpenAI, November 21, 2024.” Chicago rules on AI content say that it is appropriate to cite it in footnotes rather than the bibliography since each instance of AI output is different.
- Use footnotes and not in-text citations if you are quoting from AI
- Include the prompt in the footnotes
- You may not need to provide a citation in the bibliography.
Do I need to cite AI I only used for brainstorming?
It is determined by your class policy. If the syllabus has any rules about revealing AI use, which almost all 2026 policies do, then you’ll need to cite any AI use, including if you used it only to brainstorm. So, if all you did was brainstorm using the AI, the best way to show this is by including a disclosure statement in your paper that explains what tool you used and when. This is different from using formal citations for AI material present in your paper.
- Look into your syllabus for any guidelines on disclosure.
- Draw up a disclosure statement when using merely for brainstorming purposes.
- Formal citations should be reserved for AI material in your paper.
Can I trust the citations ChatGPT generates?
The answer is no! AI tools tend to generate faux citations that resemble legitimate ones (a phenomenon known as “hallucinated citations”). The citations generated by ChatGPT or any other AI tool should be checked against the primary source. If the source is authentic and relevant, simply give the credit to the original source. If you are unable to validate it then do not refer to it at all. Committing errors through falsified citations is the fastest way of being caught during the integrity review.
- Ai tools produce fabricated citations.
- Every AI citation should be verified against real source.
- Do not cite an AI-generated citation you cannot verify.
