Cite any source in APA, MLA, Chicago, Harvard, IEEE or Vancouver in seconds. Paste a DOI or paper title and the generator pulls the real metadata from Crossref's database of 160+ million scholarly records, then formats the reference entry and every in-text variation. Deterministic formatting, so nothing is ever invented: what you cite is what the record says.





Trusted by researchers publishing in
Paste a DOI, a doi.org link or the paper's title and the generator pulls the real metadata from Crossref's open database of 160+ million scholarly records. Books, chapters and websites can be entered manually.
Open the source details to verify authors, year, volume and pages, the thirty-second habit that keeps a reference list accurate. Every field is editable before you copy.
Copy the reference entry with italics intact for Word or Google Docs, plus every in-text form: parenthetical, narrative and quotation variants, ready to paste.
Lookups query Crossref, where publishers register their own metadata. No language model writes your citation, so a source that formats here is a source that exists.
APA 7, MLA 9, Chicago in notes and author-date, Harvard, IEEE and Vancouver, switchable with one click, each following its current edition.
Parenthetical, narrative, quotation-with-page, footnote and numbered variants are generated beside every reference entry, each with its own copy button.
Copy places rich and plain text on the clipboard together, so journal names and volume numbers arrive in Word or Google Docs already italicized.
Most writing quality lives on a spectrum; references do not. A citation either leads the reader to the source or it does not, and a reference list either matches the required style or visibly fails to. That binary quality is why markers and reviewers check references early: they are the fastest available signal of whether the rest of the work was done with care.
The mechanics deserve automation precisely because they are mechanical. Six or so styles govern nearly all academic publishing, each with fixed rules about name order, capitalization, italics and punctuation, rules a formatter applies more reliably than a tired writer at 2 a.m. This generator goes one step further than formatting: it starts from the source's registered metadata in Crossref, the database publishers themselves maintain, so the facts being formatted are the record's, not a recollection.
That design choice matters most in the AI era. Language models asked for sources routinely produce convincing references to papers that do not exist; a formatter that invents nothing, backed by a database lookup, is the natural countermeasure. The habit to build is simple: every reference in your list should have been retrieved, not remembered, and every claim should trace to a source you have actually opened.
Unsure which style your field expects? Our style comparison guide walks through the decision, and each style page above goes deep on its rules. For the prose between the citations, the AI proofreader reviews grammar and clarity with tracked changes, leaving your references untouched.
Each has a dedicated generator page with its full citation anatomy, the rules that define it, and examples for every source type.
Psychology, education, nursing and the social sciences.
Literature, languages and the humanities.
History and the humanities; two systems, footnotes or author-date.
UK universities across business, law, health and social sciences.
Engineering, computer science and applied technology.
Medicine and the life sciences, per the ICMJE recommendations.
The same journal article as each style formats it. Every difference you see, quotation marks, italics, where the year sits, is a rule, not a preference.
