Free Citation Generator Formatted From Publisher Metadata
This citation generator turns a DOI or a paper's title into a finished reference. Choose APA, MLA, Chicago, Harvard, IEEE or Vancouver, and it queries Crossref's registry of more than 160 million scholarly records for the authors, year, journal, volume, issue and pages, then arranges those facts under that style's rules to produce the reference entry and every in-text form it requires. Because the facts come from the publisher's own deposited record, the citation says only what the record says.

Turning a source into a formatted reference
Enter the DOI or the title
A DOI, a doi.org link or the article title is enough to start. The lookup runs against Crossref, the open registry holding metadata for more than 160 million scholarly records, and the fields are filled from the publisher's own deposit. Books, chapters and web pages are typed in directly.
Confirm the retrieved fields
Expand the record and read the author list, year, volume and page range before you take the entry. Registered metadata is occasionally incomplete or abbreviated, and every field remains editable once the lookup has run.
Take the your style entry
The reference list entry travels to Microsoft Word or Google Docs with its italics preserved, and the in-text forms come with it: parenthetical, narrative, and the variant used after a direct quotation.
What the generator gets right that a template doesn't
Sourced from publisher metadata
Every lookup hits Crossref's open registry, where journals register their own records. A model never guesses at an author list or a year, so what appears here is what the publisher filed.
Six styles, Chicago's two systems included
Switch among APA 7, MLA 9, Chicago's notes-and-bibliography and author-date forms, Harvard, IEEE and Vancouver without re-entering a single field. Each follows its style guide's current edition.
Every in-text form alongside the entry
Parenthetical, narrative, quoted-with-locator, footnote and numbered citations are all produced from the same lookup, so the form a sentence needs is already sitting next to the reference.
Formatting that keeps its italics
The copy button carries rich text and plain text together, so a journal title or a volume number lands in your word processor already italicized instead of needing a second pass.
Why reference formatting rewards automation
Most sentences in a paper tolerate a range of phrasing and still succeed. A reference does not work that way: it either resolves to the source or it fails outright, and a reference list either matches its assigned style or it visibly does not. Because the test is pass or fail rather than a matter of taste, it is usually the first thing a marker or reviewer checks.
That binary quality is exactly why formatting rewards a machine over a tired writer. A small number of style guides between them govern almost all academic publishing, and each fixes its own rules for name order, capitalization, italics and punctuation. This generator adds a second layer beyond formatting: it starts from the source's Crossref record rather than from what a writer half remembers about the article, so the facts entering the format are the registry's, not anyone's memory.
That distinction carries more weight now that drafting often involves a language model. Models asked to supply sources are known to produce convincing references to work that was never published, complete with a plausible journal and a DOI that resolves nowhere. A formatter that only arranges what a real registry returns cannot do that, which makes an entry that fails to resolve here worth investigating before it reaches a submission.
Choosing among the six styles is covered in our style comparison guide, and each dedicated style page above goes further into its own rules. Once the references are settled, the TextPulse humanizer can rework the surrounding prose without disturbing a single entry.
Six rule systems, one lookup
Every card below leads to a page built around a single style: its own element-by-element anatomy, the rules unique to it, and examples across several source types.
APA 7
OpenThe default across psychology, education, nursing and the wider social sciences.
MLA 9
OpenStandard in literature courses, language departments and the humanities generally.
Chicago 18
OpenHistory and the humanities, split between two citation systems inside one manual.
Harvard
OpenCommon at UK universities, spanning business, law, health and social-science degrees.
IEEE
OpenThe house style for engineering, computer science and applied-technology journals.
Vancouver
OpenMedicine and the life sciences, built around the ICMJE's numbered-reference scheme.
The same reference, run through six rule sets
Below, one journal article renders six different ways. Every visible choice, the punctuation, the italics, the position of the year, is dictated by that style's own manual.
