How to Cite ChatGPT in APA, MLA, and Harvard

As AI tools become part of student workflows, universities now require transparent disclosure of their use. Citing ChatGPT correctly is not just good academic practice — in most institutions it is mandatory. Submitting AI-generated content without attribution is treated as a form of plagiarism and can carry serious academic penalties.

This guide covers exactly how to cite ChatGPT in APA, MLA, and Harvard formats, with copy-ready examples for in-text citations and reference list entries. Need help ensuring your academic work is fully compliant and properly cited? The experts at Academia Helper can assist.

Quick Summary: Always cite ChatGPT when using its output in academic work. Use OpenAI as the author, include the model version, the date of your response, and the URL. Formats differ between APA, MLA, and Harvard — examples for each are below.

Why You Must Cite ChatGPT

Failing to declare AI use — and presenting its output as your own — is considered a form of academic misconduct by most universities. Beyond policy compliance, citing ChatGPT also:

• Allows readers to understand how findings or ideas were generated
• Acknowledges the AI tool's role in your research process
• Protects you from plagiarism accusations
• Demonstrates academic transparency and integrity

What You Need to Cite ChatGPT

Across all citation styles, you will need the same core elements:

How to Cite ChatGPT in APA 7th Edition

In APA 7, ChatGPT is treated as a personal communication (non-retrievable) or a software tool (if the output is retrievable via a shared link). For most student use cases — private conversations — treat it as a personal communication.

In-text citation (personal communication):

Reference list entry (retrievable / shared link):

If the conversation is not retrievable, include only the in-text citation with a note such as: [ChatGPT response to the prompt "your question here," 15 July 2025]. Do not add a reference list entry for non-retrievable personal communications.

How to Cite ChatGPT in MLA (9th Edition)

MLA treats the prompt you entered as the title of the work and places it in quotation marks.

Works Cited entry:

In-text citation:

MLA shortens the in-text reference to the first few words of the prompt title. Note that MLA also advises disclosing AI tool use in a note or acknowledgement section, particularly for editing or translation use.
