Free ChatGPT Citation Generator OpenAI as Author, Done Properly
Cite ChatGPT correctly in APA 7, MLA 9, Chicago 17, Harvard, IEEE and Vancouver. OpenAI and the tool's URL are already filled in; add the version from the model picker, the date and your prompt, and copy the reference entry with every in-text form. Built on the guidance APA, MLA and Chicago published specifically for citing ChatGPT.
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 ChatGPT in three steps
Pin down the version
Open the model picker or settings in ChatGPT 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.
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.
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 ChatGPT citation generator is different
The published patterns
ChatGPT is the tool the style manuals wrote their AI guidance around. The APA Style blog's worked example, MLA's prompt-as-title approach and Chicago's notes-only ruling are each applied exactly.
OpenAI prefilled
Company, tool name and URL are already in the form. You supply only what belongs to your conversation: the version, the date and the prompt.
Version-aware citations
GPT models change between releases, so the version from the picker is what makes your citation reproducible. The generator puts it exactly where each style wants it.
Every in-text form
Parenthetical and narrative citations, Chicago's full and shortened notes, and the disclosure wording IEEE and Vancouver expect all come with the entry.
Citing ChatGPT: the tool the manuals answered first
When academia had to decide how generative AI gets cited, ChatGPT was the test case. The APA Style blog published its worked example in 2023: OpenAI in the author position, because the company is credited with the algorithm's output; ChatGPT italicized as the title; the version in parentheses; a bracketed descriptor so readers know what kind of source they are looking at. MLA answered with the reverse philosophy, building the entry around your prompt because an AI cannot hold authorship. Chicago filed the whole question under personal communication: a footnote, and nothing in the bibliography.
Every one of those patterns hinges on details that are easy to lose by the time you write the reference list: which GPT version answered you, on what date, to what prompt. ChatGPT's answers differ between model releases and even between sessions, so the manuals treat the version and date the way they treat a book's edition and year. The safest habit is to record all three the moment a conversation produces something you might use, and to keep the transcript for an appendix.
Citing ChatGPT honestly also means not citing it for things it did not do. Papers it recommends are cited as papers, after you have verified they exist; assistance that left no words in your text is disclosed rather than cited. The AI citation checker verifies recommended references against real databases, and the AI citation generator handles the other nine model families. When the citing is done and the prose still sounds like a chatbot, the TextPulse humanizer rewrites the rhythm while your citations stay frozen.
