CardCite

Built for debate and academic research, CardCite pulls accurate citations from any webpage or PDF in one click.

On any page, open CardCite from the puzzle piece icon at the top right of Chrome. CardCite automatically detects the details it needs, then formats them into a finished citation that's ready to copy and paste. Every field stays editable before you copy it.

CardCite does not use AI to detect or format any part of a citation: every detail comes from the source itself, read from the page's own data and visible text, or drawn from public catalogs of published work when the page leaves one out. Tested rigorously on hundreds of websites and PDFs, CardCite delivers the correct publisher, date, author, and title with a very high degree of accuracy. Publisher names are checked against a built-in list of over 50,000 domains, so an article at nytimes.com is cited as The New York Times, and author candidates are screened against a list of over 120,000 words that appear in ordinary English but never in real names. Additional details on accuracy and how CardCite's detection logic works can be found on the website, cardcitesource.com

PDFs are fully supported. CardCite reads the document itself, so reports, working papers, and journal articles cite just as cleanly as a news article.

CardCite is built to be highly customizable: in the extension's settings, you can use the default style or customize the citation format, including font size, field order, brackets, bold, italics, underline, line breaks, and your team name, or switch to a built-in preset: MLA 9, APA 7, or Chicago 18. These changes are saved and applied to every citation you create.

CardCite includes optional source descriptions for over 1,000 major news outlets, think tanks, journals, and government agencies, which are added to the citation automatically when the source is recognized. For a source that isn't included, you can save your own description once, and CardCite will remember it whenever you cite that source again.

Highlight text on a page before you open CardCite and it is carried below the citation when you paste it into a document. The quote defaults to plain 12pt Times New Roman and can be edited in the popup: select any words inside it and bold, italicize, underline, or resize them.

You can also save citations to a built-in library to search, edit, and copy them later.
