Does Purdue OWL Have a Citation Generator?

No. The Purdue Online Writing Lab (OWL) is a free style guide: it explains APA, MLA, Chicago and other formats with examples, but it does not run a citation generator of its own. When a search for a "Purdue OWL citation generator" leads you to a generator, that tool belongs to someone else.

Since March 2019, Purdue has had an agreement with Chegg, the company behind Citation Machine, EasyBib, BibMe and Cite This For Me, under which Chegg's citation tools appear alongside OWL content. Those generators are Chegg products; the OWL pages remain the style reference.

The OWL has its own page on using citation generators responsibly. Its point is that a generator can introduce errors you do not notice, so treat what it produces as a draft and check it against the rules for your style. University library guides give the same advice: a generator formats whatever details it receives, so a wrong author, year or title comes out neatly formatted and still wrong.

• Wrong details: a missing or misspelled author, the wrong year, a shortened title, missing volume or page numbers, a broken DOI, or a different paper with a similar title.
• Wrong format: capitalization, the author-list rule, italics and quotation marks, how the DOI is written, or an outdated edition of the style.

The OWL's pages help with the second kind. The first kind needs the source itself: the publisher page, the DOI record or a database entry.

• Edition: APA 7th and MLA 9th are the current editions. A generator that still defaults to APA 6 or MLA 8 will format some sources differently.
• Authors: APA 7 lists up to 20 authors; MLA 9 gives the first author followed by "et al." when a source has three or more.
• APA 7 titles: sentence case for article and book titles; the journal name and volume number are italic.
• APA 7 DOIs: written as https://doi.org/ links, without "Retrieved from" or a "doi:" label.
• MLA 9 titles: title case; a source inside a larger container, such as an article in a journal or a page on a website, goes in quotation marks and the container in italics.
• Details: open the DOI or the publisher page and confirm that the author names, year, title and page range match the citation.

CiteMe's APA and MLA generators search OpenAlex, CrossRef, PubMed and Semantic Scholar for the source record and show which record they used, so you can compare the details before you copy the citation. If you already have a reference list, from any generator or from an AI chat tool, the reference checker matches each entry against database records and flags the ones with no acceptable match.

Use the OWL for the formatting rules and the source record for the details. Either way, read the final citation once against your style before you submit.
