ProofreaderPro.ai

Free Citation Generator

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.

Formats journal articles, books, chapters and websites. Lookups use Crossref's open database.

How to generate a citation in three steps

01

Find your source

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.

02

Check the details

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.

03

Copy in your style

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.

Why this citation generator is different

Real records, not AI guesses

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.

Six styles, both Chicagos

APA 7, MLA 9, Chicago in notes and author-date, Harvard, IEEE and Vancouver, switchable with one click, each following its current edition.

In-text forms included

Parenthetical, narrative, quotation-with-page, footnote and numbered variants are generated beside every reference entry, each with its own copy button.

Italics survive the paste

Copy places rich and plain text on the clipboard together, so journal names and volume numbers arrive in Word or Google Docs already italicized.

Citations: the part of writing where accuracy is binary

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.

The six styles most researchers use

Each has a dedicated generator page with its full citation anatomy, the rules that define it, and examples for every source type.

One article, six styles, side by side

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.

Citation generator FAQs

Which citation styles are supported?
The six that cover the overwhelming majority of academic work: APA 7, MLA 9, Chicago 17 in both of its systems (notes and bibliography, and author-date), Harvard in the Cite Them Right format, IEEE, and Vancouver. Each has a dedicated page with its full anatomy, rules and examples.
Where does the citation data come from?
From Crossref, the registry where publishers deposit the metadata for over 160 million scholarly records. Paste a DOI, a doi.org link or a title, and the generator retrieves the registered authors, year, journal, volume, issue, pages and DOI, then formats them deterministically. No AI model writes the citation, so nothing is invented.
Can it also cite books, chapters and websites?
Yes. Many books and chapters resolve through Crossref by title or DOI; anything else can be entered manually, including corporate authors and access dates for websites. The manual form adapts its fields to the source type.
How does the citation generator run?
Formatting happens in your browser from the details you enter. The only network request is the optional metadata lookup against Crossref's open API, which receives the search text alone.
