This is EdCitation's view, and it decides how every one of our tools is built: a reference is a promise. It tells your reader that the source exists, and that it says what your sentence says it says. That is why EdCitation looks every reference up in a publisher's record and never writes one, and why we think a reference a chatbot composed from memory should never reach a reader.
The promise breaks in two ways. A source can be invented, as language models do for reasons Why AI tools invent references explains, or a real source can be made to say something it does not. This guide covers what the style guides say a reference is for, and what universities say about references written by AI.
The first half of the promise can be checked by looking things up: EdCitation's free Verify references does it for a whole list, and Cite a source builds each entry from a record. The second half is kept only by reading.
What is the purpose of a reference?
A reference exists so that a reader can find the exact work you used and check your claim against it. Each style says so in its own words.
| Style | What its own pages say | The promise it implies |
|---|---|---|
| APA 7 | References give readers what they need "to identify and retrieve each work cited", and writers cite only works they have read (American Psychological Association, 2022, 2023) | The work exists, and you read it |
| MLA 9 | Citation lets writers alert readers "to the trustworthiness of their findings" (Modern Language Association, n.d.) | The finding can be traced |
| Chicago 18 | Authors "are expected to have examined the works they cite", from paragraph 14.160, quoted in Chicago's Q&A (University of Chicago Press, n.d.-a) | You looked at it yourself |
| Harvard (Cite Them Right) | Referencing acknowledges other people's work "when you have used it as evidence" (Cite Them Right, n.d.) | It is evidence for this point |
| Any of the six we offer | Build the entry from the work's record | EdCitation's Cite a source: APA 7, MLA 9, Chicago 18 author-date, Harvard, IEEE, Vancouver |
Two halves of one promise
Read together, the four make two promises of every entry. The first is existence: a work with these authors, title and date is there to retrieve. The second is fidelity: it supports the sentence beside it. APA asks writers to check each entry "against the original publication" (American Psychological Association, 2023), which covers the first; its rule to cite only what you have read covers the second.
A tool can check the first half by finding the record. Nothing can check the second for you. If you met an idea second-hand, I cited a source I did not read gives the honest form in each style.
What we could not read in full
Harvard has no single publisher. EdCitation's Harvard follows Cite Them Right, whose articles sit behind a subscription, so we quote only the summary its page makes public. Chicago's chapter on citation is subscription-only too; its line above comes from the free Q&A.
Why do we cite sources at all?
We cite sources so that a reader never has to take our word for anything: a citation hands over the evidence and credits the people who did the work.
Even careful writers break the second half. Smith and Cumberledge (2020) took 250 random citations from high-impact general science journals and compared each cited claim with the work it pointed to: in 25%, the source did not substantiate the claim. Every one of those references existed. Our roundup of citation errors in published research sets that figure beside a dozen others.
When a reference becomes a token
In 2025, Deloitte Australia agreed to repay the final instalment of an AU$440,000 contract with Australia's Department of Employment and Workplace Relations, after its 237-page report was found to cite non-existent academic papers and to include a fabricated quotation from a federal court judgment (McGuirk, 2025). Chris Rudge, the University of Sydney researcher who found up to 20 errors, said colleagues' work had been used as "tokens of legitimacy": cited, but not read. The revised report disclosed that Azure OpenAI, a generative AI system, was used in writing it; Deloitte did not say whether the errors came from AI.
The same year, the news site NOTUS found that at least seven citations in the "Make America Healthy Again" Commission's report on children's health appeared not to exist. Within hours a new version had replaced all seven, and the White House blamed "formatting issues" (Manto, 2025). Whether AI tools were used was never confirmed. Either way, readers had been promised studies that were not there.
In the courts
Charlotin (2026) tracks legal decisions in which generative AI produced hallucinated content: 2,125 cases when we read the database on 2 October 2026. Its labels map onto the two halves of the promise: 1,752 cases involve fabricated material and 894 misrepresented material, and a case can carry both.
Can AI write my references?
Not from memory, in our view, and never without a record behind each one. A chatbot asked for references writes text in the shape of a reference, and nothing in that step checks that the work exists. Walters and Wilder (2023) had ChatGPT write 84 short literature reviews and checked all 636 references: 55% of GPT-3.5's and 18% of GPT-4's were fabricated, and 43% and 24% of the real ones carried substantive errors. Later models have done better in some tests and worse in others; what studies say about AI-fabricated references sets them out model by model.
The MLA now says so itself. Its August 2025 guidance on citing generative AI warns that AI tools "can also hallucinate, or make up, sources" or summarise wrongly what they do cite, and recommends consulting and citing those sources directly (Modern Language Association, 2025).
What about AI tools that search the web?
Search helps with the first half and leaves the second where it was: the page may exist, but a language model still writes the sentence saying what it contains. Click through, read, and cite the source itself. A tidy format proves nothing either: a model can set an invented paper in flawless APA 7. A tool may format a record; it should never supply one.
Is it OK to use AI to make a reference list?
Only if your course allows AI for that task, and even then every policy we read, on 2 October 2026, leaves the list your responsibility.
| Institution | What its published guidance says |
|---|---|
| University of Toronto, School of Graduate Studies | AI tools "have also been shown to reference scholarly works that do not exist"; students "remain responsible" for their thesis whatever sources they use (University of Toronto, School of Graduate Studies, 2026) |
| University of Birmingham | AI tools are known to "commonly ‘hallucinate’ references which do not exist"; double-check what they give you (University of Birmingham, n.d.) |
| Assiniboine College, Canada | Sources from misused generative AI "may not exist", and including them "will be viewed as fabrication" (Assiniboine College Library, 2026) |
| Florida State University | Guidance for faculty names "use of AI to generate false citations" as falsification (Florida State University, n.d.) |
| University of Liverpool | Lists false references first among signs staff may look for, "as guidance only", not definitive proof (University of Liverpool, n.d.) |
| COPE, for journals | Authors are "fully responsible" for their manuscript, including parts an AI tool produced (COPE Council, 2023) |
Where the policies differ
They differ on what an invented reference is. Assiniboine and Florida State treat it as fabrication or falsification; Liverpool treats it as a sign worth a closer look, not proof of AI use. Assiniboine also goes further than the style guides: even citing a secondary source without reading the original "may be considered fabrication", where APA asks only that secondary sources be cited sparingly (American Psychological Association, 2022). Your own institution's wording is the one that applies.
Chicago's answer on citing AI text points authors to COPE's position (University of Chicago Press, n.d.-b), the plainest statement we found: an AI tool cannot be an author because it "cannot take responsibility for the submitted work". If AI is allowed on your course, How to declare AI use in an assignment covers what to write.
Why does EdCitation never write a reference?
Because a written reference has nothing behind it but its wording, and a looked-up one has a record. Every entry EdCitation gives you starts from a record held by a publisher, registry or library, such as Crossref or PubMed; where none exists, it says so. EdCitation never writes any part of anyone's work: your argument, your sentences and your reading stay yours, and what we add is the record and the check.
That makes Verify references the best tool for the first half of the promise, and a chatbot the wrong one. Walters and Wilder (2023) found more than half of GPT-3.5's references fabricated, and an invented paper has no record for a lookup to find; a model rereading its own text cannot tell. Paste a list or upload the paper, free and with no account. Each entry comes back verified, "check this" (doubtful) or not found; retracted papers are flagged; and an entry that could not be checked is never reported as not found. With the whole paper uploaded, every in-text citation is matched to the list and every entry back to the text.
Cite a source builds an entry from a DOI, title, PubMed ID, ISBN or web address, in six styles, screened for retraction, and Find sources searches about 300 million published works when a sentence still needs support. All three are free. Pro, at $8 a month, adds References from a file, which checks every reference in an uploaded paper and matches each in-text citation to the list; Max, at $24 a month, adds Theoretics QA and the Library (pricing).
What our two runs returned
On 2 October 2026 we put two entries into Verify references: the Walters and Wilder (2023) entry from our list below, and one we wrote for this test. The second is ours, and no such paper exists:
Okafor, L. M., & Brandt, S. J. (2024). The reference as a promise: Reader trust and citation accuracy in first-year undergraduate essays. Journal of Academic Ethics, 22(3), 411–429.
| Entry | Verdict | Reason, as returned |
|---|---|---|
| Walters and Wilder (2023), with its DOI | verified | "The DOI resolves to this record and the title matches." |
| Our invented entry | not found | "No publisher's or registry's record matches this reference." |
The counts: 1 verified, 0 doubtful, 1 not found, 0 retracted, 0 unchecked. Our entry names a real journal with plausible details, and still has no record. For a thesis or a report a missing record is weaker evidence, as My reference cannot be found explains.
We then gave Cite a source the DOI of the Smith and Cumberledge (2020) study. It came from Crossref's record with no retraction notice, and the APA 7 entry read:
Smith, N., Jr, & Cumberledge, A. (2020). Quotation errors in general science journals. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 476(2242), Article 20200538. https://doi.org/10.1098/rspa.2020.0538
Its in-text citation, (Smith & Cumberledge, 2020), leaves the suffix out, as APA asks (American Psychological Association, 2019). The entry keeps "Jr" as the publisher deposited it, with no full stop, while APA's own page writes "Jr.": compare the entry with the paper, since a record is only as exact as its deposit.
How do I keep the promise in my own paper?
Treat every reference as something you may be asked to produce. In order:
- Start from the claim. Search for published work that supports the sentence in EdCitation's Find sources, which takes the claim itself as the search.
- Read the part you will cite. That half of the promise is yours alone.
- Build the entry from the record in Cite a source, in your course's style.
- Treat anything an AI tool suggests as a lead. Look it up and open it before it goes near your list.
- Check the finished list in Verify references, or upload the whole paper so citations and entries are matched both ways.
- Settle every "check this" and every not found. Correct details from the record; replace a source that does not exist, and the sentence it held up.
- Declare any AI use the way your course asks.
Quick questions
What is the purpose of a reference list?
A reference list lets a reader identify and retrieve every work cited in the text. APA also requires every cited work to appear in the list and every listed work to be cited, so the list maps your evidence.
Why do we cite sources in academic writing?
So the reader can check where each idea and fact came from, the people who did the work are credited, and your contribution is kept apart from theirs.
Can ChatGPT write my reference list?
Not safely from memory. In one test, 55% of GPT-3.5's references and 18% of GPT-4's did not exist (Walters & Wilder, 2023). Build each entry from its record with EdCitation's free Cite a source, then check the list.
Is handing in an AI-invented reference misconduct?
It can be. Assiniboine College says including such sources will be viewed as fabrication, and Florida State's guidance counts AI-generated false citations as falsification. Read your own institution's policy.
Can EdCitation write my references for me?
No, and that is the point. EdCitation looks every reference up in a publisher's record and builds it from what the record holds. It never writes a reference, or any other part of your work.
