ProofreaderPro.ai

Free AI Citation Generator

Cite ChatGPT, Claude, Gemini, Copilot and other AI tools correctly in APA 7, MLA 9, Chicago 17, Harvard, IEEE and Vancouver. Pick the tool, add the version, date and prompt, and copy the reference entry with every in-text form, built on the guidance the style manuals published for generative AI. Ten model families are preset; any other tool takes a few keystrokes.

Pick the tool you used

The version is in the product's model picker or settings. The prompt makes MLA, Chicago and Harvard entries complete; APA works without it.

How to cite an AI model in three steps

01

Pin down the version

Open the model picker or settings in your AI tool and note the exact version you used. AI tools change weekly, so the version is what makes your citation reproducible, the same way an edition dates a book.

02

Add the date and prompt

Record when the text was generated and what you asked. MLA and Chicago build the citation around the prompt itself, and every style dates the exchange somewhere.

03

Copy in your style

Pick APA, MLA, Chicago, Harvard, IEEE or Vancouver and copy the entry with italics intact, plus the in-text forms and the note or disclosure wording the style expects.

Why this AI citation generator is different

The official patterns, not guesses

APA, MLA and Chicago published real guidance for citing AI in 2023, and each output here follows it: company as author for APA, prompt as title for MLA, notes-only for Chicago.

Ten model families preset

ChatGPT, Claude, Gemini, Meta AI, Copilot, Grok, DeepSeek, Le Chat, Perplexity and Qwen come with company and URL filled in. You add only what is yours: the version, date and prompt.

The disagreements handled

Chicago wants no bibliography entry, MLA wants no author, Harvard wants an appendix and IEEE wants an acknowledgment. The generator changes shape per style instead of forcing one template on seven rulebooks.

Italics survive the paste

Copy puts rich and plain text on the clipboard, so model names arrive in Word or Google Docs already italicized where the style wants them.

Citing AI: what the style manuals actually decided

For a year after ChatGPT's release, citing it was guesswork. Then the manuals answered, and they answered differently. APA reasoned that the output of an algorithm belongs to the company that made it, so OpenAI or Anthropic takes the author position, with the model italicized as the title and the version in parentheses. MLA reached the opposite conclusion: an AI cannot be an author at all, so the entry is built around your prompt, with the tool as the container it appeared in. Chicago looked at the same problem and filed it under personal communication, cited in a footnote or in the text and never in the bibliography.

What all three agree on is the details that make the citation reproducible: which version, and when. A model's answer to the same prompt differs between releases and even between days, which is why every pattern here dates the exchange and why the version field matters more than it does for any book. It is also why the guides point readers at the tool's URL rather than a chat link, and suggest keeping the full transcript in an appendix.

One line has hardened across academic publishing: an AI model is never an author. The ICMJE and COPE both hold that AI cannot meet authorship criteria because it cannot take responsibility for the work, and publishers including Nature and Science have written the same rule into their policies. In practice that means two obligations that travel together: cite AI output where it appears in your text, and disclose AI assistance where your journal or university asks for it, usually in the methods or acknowledgments.

The other half of AI citation hygiene concerns the sources a model recommends. Language models invent plausible references, so any paper an AI suggests needs verifying against a real database before it enters your reference list; our hallucinated-citation audit walks through the check, and the main citation generator formats real records straight from Crossref. For how we think about responsible AI use in academic writing more broadly, see our AI use policy.

How the six styles treat AI differently

Seven outputs, four philosophies. These are the decisions each manual made, and the generator applies.

APA: the company is the author

OpenAI, Anthropic or Google takes the author position, credited with the algorithm's output. The model is italicized as the title, the version sits in parentheses, and a bracketed [Large language model] tells readers what the source is.

MLA: the prompt is the title

MLA declines to treat the AI as an author. The entry opens with your prompt in quotation marks, the tool becomes the italicized container, and the in-text citation is a shortened form of that prompt.

Chicago: notes only

The Chicago Manual treats AI output like personal communication: a numbered footnote carries the model, prompt, company and full date, and nothing appears in the bibliography, in either Chicago system.

Harvard: a personal communication

Cite Them Right files generative AI under personal communications because your reader cannot retrieve the exchange. The maker and tool are the originator, and the transcript belongs in an appendix.

IEEE: cite and disclose

IEEE has no official AI template, so the software pattern stands in. What IEEE does mandate is disclosure: AI-generated content must be declared in the acknowledgments, alongside any reference.

Vancouver: the ICMJE line

Medical journals follow ICMJE, which requires AI use to be described in the methods or acknowledgments and bars AI from authorship. The reference itself adapts NLM's software pattern.

AI citation generator FAQs

Should I cite AI output, or just disclose that I used AI?
Both have a place, and they answer different questions. If the AI's words or ideas appear in your text, quoted, paraphrased or summarized, they need a citation like any other source. If the tool assisted your process, brainstorming, editing or translating, most journals and universities want a disclosure statement in the methods or acknowledgments instead. Many situations call for both, so check the policy of the journal or department you are writing for.
Which citation styles have official guidance for AI?
Three published it in 2023 and the generator follows each one: the APA Style blog's pattern with the company as author and the version in parentheses, the MLA Style Center's approach with the prompt as the title of the source, and the Chicago Manual's Q&A ruling that AI is cited in a note or in the text, never in the bibliography. Harvard, IEEE and Vancouver have no official template yet, so the generator applies the personal-communication and software patterns university guides derive from those manuals.
Can an AI model be listed as an author of my paper?
No. The ICMJE and COPE have both stated that AI tools cannot meet authorship criteria, because they cannot take responsibility for the work, and major publishers including Nature and Science have adopted the same position. The AI is cited or disclosed as a tool; the accountability stays with the human authors.
Where do I find the model version?
In the product itself: ChatGPT and Le Chat show the model in the picker at the top of a chat, Claude shows it in the model menu, Gemini in its version selector, and most tools list versions in their settings or release notes. Cite the version you actually used; AI products change too often for an unversioned citation to be reproducible.
