How to Cite ChatGPT: The Quick Answer
Knowing how to cite ChatGPT correctly comes down to two things: following your required style guide and being transparent about how you used the tool. APA and MLA have both released official guidance, and while the formats differ, the core principle is the same - document what the tool is, who made it, and when you accessed it.
Below we cover both formats with copy-ready examples, explain the reasoning behind each element, and flag a few things your professor may also expect beyond the citation itself.
Key Takeaways
- APA: Treat OpenAI as the author, name the specific model version, and link to chat.openai.com.
- MLA: Use "ChatGPT" as the author, describe your prompt as the title, and include your access date.
- Neither format requires you to paste the full conversation, but keeping a saved copy is smart practice.
- Citing is only one part of transparency - your institution may also require a disclosure statement in your paper.
How to Cite ChatGPT in APA Format
The American Psychological Association updated its guidance to cover AI-generated text. The reference entry follows the same logic as citing software or an algorithm.
APA Reference List Format
Author. (Year). Title of model (Version) [Description]. URL
APA Example
OpenAI. (2024). ChatGPT (GPT-4o) [Large language model]. https://chat.openai.com
Let's break down each element:
| Element | What to Use |
|---|---|
| Author | OpenAI |
| Year | Year you generated the response |
| Title | ChatGPT (italicized) |
| Version | The model name shown in the interface (e.g., GPT-4o) |
| Description | [Large language model] in square brackets |
| URL | https://chat.openai.com |
APA In-Text Citation
(OpenAI, 2024)
If you quote or closely paraphrase a specific response, APA recommends describing the prompt in your prose or a footnote, because the response cannot be retrieved by a reader the way a webpage can. For example:
When asked to summarize the causes of World War I, ChatGPT (OpenAI, 2024) identified four main factors...
ChatGPT's behavior changes significantly between model versions. GPT-3.5 and GPT-4o can give meaningfully different answers to the same prompt. Including the version helps a reader understand the context of the output you received.
How to Cite ChatGPT in MLA Format
The Modern Language Association takes a slightly different approach. MLA treats the text generated by ChatGPT as content you received from a source, so your prompt acts as the "title" of that piece of content.
MLA Works Cited Format
"Description of prompt." ChatGPT, OpenAI, Day Month Year, URL.
MLA Example
"Explain the main causes of World War I in simple terms." ChatGPT, OpenAI,undefinedMar. 2024, chat.openai.com.
Here is what each part means:
| Element | What to Use |
|---|---|
| Title | A short description of your prompt, in quotation marks |
| Container | ChatGPT (italicized, as the source title) |
| Publisher | OpenAI |
| Date | The date you received the response |
| URL | chat.openai.com (drop the https://) |
MLA In-Text Citation
("Explain the main causes")
If that abbreviated title is awkward, MLA allows you to use a signal phrase instead:
According to a ChatGPT response generated onundefinedMarch 2024, the causes of World War I include...
ChatGPT conversations are not publicly accessible. Your reader cannot verify the output from a URL alone. Save a screenshot or export the chat as a PDF so you can share it with a professor or journal editor if asked.
What About Chicago, Harvard, or Other Styles?
We focused on APA and MLA because they are the most commonly requested, but the principles transfer:
- Chicago (Notes-Bibliography): Cite OpenAI as the author, name the model, include the date of access, and add the URL in a footnote and bibliography entry.
- Harvard: Follow the software citation pattern - author (OpenAI), year, tool name and version, available at URL, accessed date.
- IEEE: Treat it as an online source with OpenAI as the corporate author and include the access date.
If your institution or journal uses a style not listed here, look up that style's guidance on citing software or unpublished/non-retrievable sources - ChatGPT fits closest to those categories.
Does Citing ChatGPT Mean You Can Use It Freely?
Not necessarily. A citation documents your source; it does not automatically make AI use acceptable under your institution's rules.
A few practical checks before you submit:
- Read your syllabus or assignment brief. Many instructors now explicitly allow or ban AI tools on a per-assignment basis.
- Check your institution's academic integrity policy. Policies are evolving fast, and what was unaddressed inundefinedmay now carry a penalty.
- Disclose AI use in your paper. Some journals and many instructors ask for a brief methods note explaining how you used AI (e.g., for brainstorming, drafting, or editing).
If you want to understand how AI-generated text reads to detection tools before you submit, you can run your draft through our free AI detector test to see what signals reviewers might pick up.
When You Paraphrase vs. Quote ChatGPT
Both APA and MLA treat paraphrasing and direct quotation differently:
- Direct quote: Use quotation marks around the exact output, cite in-text, and include the full reference/works-cited entry.
- Paraphrase: No quotation marks, but still include an in-text citation and the reference entry. Do not present AI-generated ideas as your own original thinking without attribution.
A practical tip: treat AI output the way you would treat a reference book. It can inform your argument, but your analysis, synthesis, and interpretation should be your own.
A Note on "Humanized" AI Text and Academic Honesty
Some students rewrite AI-generated drafts to make them sound more natural before submission. Rewriting is a legitimate editing process, but it does not remove the citation obligation if the ideas or structure came from ChatGPT.
If you are working on making your writing more natural and personal, our free AI humanizer can help you reshape AI-assisted drafts into your own voice - but the source still needs to be cited honestly. Humanizing text and citing it are two separate, compatible steps.
Ask yourself: if your professor saw the original ChatGPT output next to your submitted work, would they feel informed or misled? If the answer is "misled," you likely need a clearer citation or disclosure statement.
Common Mistakes to Avoid
- Leaving out the model version: "ChatGPT" alone is not specific enough. GPT-4o and GPT-3.5 produce different outputs.
- Using a retrieval date as the publication date: In APA, the date is the year you generated the response, not today's date.
- Skipping the in-text citation: A works-cited entry without a corresponding in-text citation is incomplete in both APA and MLA.
- Citing one conversation to cover many: If you used ChatGPT multiple times for different sections, consider noting that in your disclosure statement.
The Short Version
How to cite ChatGPT in APA: OpenAI. (Year). ChatGPT (Model version) [Large language model]. https://chat.openai.com - with an in-text citation of (OpenAI, Year).
How to cite ChatGPT in MLA: "Description of your prompt." ChatGPT, OpenAI, Date, chat.openai.com - with an in-text citation using the first word(s) of the title.
Beyond the format, the real rule is simple: be transparent. Save your conversation, note the model version, and check whether your institution requires a separate AI disclosure statement. Citing correctly is the foundation of academic honesty when working with AI tools.
Frequently asked questions
How do you cite ChatGPT in APA format?
List OpenAI as the author, include the year, name the model version as the title, and provide the URL. Example: OpenAI. (2024). ChatGPT (GPT-4o) [Large language model]. https://chat.openai.com
How do you cite ChatGPT in MLA format?

Do you need to include the ChatGPT prompt in your citation?
MLA recommends including a description of your prompt as the title element. APA does not require the prompt in the reference list entry, but suggests describing it in your text or a footnote.
Is using ChatGPT without citing it considered plagiarism?
Most academic institutions treat undisclosed AI-generated content as a form of academic dishonesty. Always check your institution's policy, and cite or disclose AI use when in doubt.
