Problems & solution

Your problem, our solution

What students are tired of with old citation sites, and how CitApp fixes it.

The old tools

  • A handful of styles, ads everywhere
  • Paywall just to copy your own citation
  • Manual entry for every field
  • Blocked on sources behind paywalls
  • Sources scattered across tabs and docs

With CitApp

  • 150+ styles, journal and university ones included, and no ads
  • Build and copy your whole list free, no account needed
  • Automatic metadata from DOI, PubMed, arXiv & books
  • Reaches paywalled sources and finds authors on broken pages
  • Projects & categories, plus export to BibTeX, RIS and Word
How it works

From web page to finished source, in two clicks

No more copying links into a Google doc, losing half of them, and piecing together your reference list the night before the deadline.

Step 3

Cite in any style

Citation + reference list, correctly formatted in the style your course requires.

More than a generator

Built for how you actually write

Beyond the 150+ styles: make a style your own, reach journal styles with CSL, and cite right where you write.

Create your own citation style

Course wants a local Harvard variant? Build the style once with a simple template and every citation formats itself.

Build your style

130+ journal styles with CSL

Pick your journal’s exact style by name, built on the same open standard Zotero and Mendeley use.

Browse journal styles

Cite as you write in Google Docs

A sidebar add-on that inserts the citation at your cursor and keeps the reference list updated, no tab switching.

Trust & accuracy

Citations you can actually trust

Academic sources are pulled from authoritative databases, not guesses. You always see the details and can adjust before you copy.

Never lose a source again

No more unsynced tabs, half-pasted links in a document, and references you can’t find again. Everything you save is collected, sorted and kept, ready when you write.

Pulled from real databases

Metadata comes straight from CrossRef, PubMed, arXiv and Google Books, so authors, dates and page numbers are correct, not invented.

Understand the source, without cheating

An AI summary of each source, short enough that you still have to put it in your own words. An honesty tool, not a cheating tool.

FAQ

Frequently asked questions

Is CitApp free?
Yes, unlimited sources, all 150+ styles and the full AI reference list are free forever, with no ads. Saving via the browser extension or bookmarklet is free up to 10 times a week. The Google Docs add-on is free too: the free plan includes 30 citation insertions and 10 Academic Shield checks a week. PDF upload, importing from Zotero or Mendeley and every export are free too. Pro removes the weekly limits and adds Understand the source and the page archive.
How accurate are the citations?
Metadata is pulled from authoritative databases (CrossRef, PubMed, arXiv, Google Books), then formatted with the same CSL engine used by Zotero and Mendeley. You always see every field and can edit before you copy.
Which styles are supported?
17 built-in styles including APA, MLA, Harvard, Chicago, IEEE, Vancouver, Oxford and OSCOLA, plus 130+ journal and university styles via CSL. You can also build your own.
Does CitApp work on a school Chromebook?
Yes. CitApp runs in the browser, so citing, saving sources to projects and building your reference list need nothing installed. If your school blocks browser extensions, the bookmarklet saves the page you are reading instead: it is a bookmark, not an extension. The Google Docs add-on comes from the Google Workspace Marketplace, which some school accounts only allow once an administrator has approved it.
Can I use it for a group project?
Yes. Open a project, press Share and send the invite link. Anyone with the link who signs in can view the project and add sources to it, so the whole group builds one reference list. Sharing is free.
Do I need to create an account?
No. Right here you can cite a source, switch between APA, Harvard, MLA and the other common styles, build a whole reference list and download it for Word or as a .ris file, all without signing up. An account adds projects, syncing across your devices, the browser extension and the Google Docs add-on.
Will my sources still be there next term?
Yes, once they are in an account. Every source you save goes into your account, not your browser, so clearing your history or moving to a new laptop or phone loses nothing, and that is free. The list you build on this page without an account is kept only in this browser. And every project exports to Word, BibTeX or RIS for free whenever you want your own copy.

Highlight. Save. Done.
