AllCitations vs Paperpile: Free Generator or Paid Manager

Paperpile is a paid reference manager built around Google Docs. AllCitations is a free citation generator that runs in a browser tab. The AllCitations vs Paperpile decision usually comes down to one question you can answer in about ten seconds: are you building a library you will still be using in two years, or do you have eleven sources and a submission portal closing tonight?

Every claim below about Paperpile comes from pages on paperpile.com fetched on 21 September 2026. Claims about AllCitations come from the app's own style list and the code that generates its output. Where a page could not be fetched, the claim is left out.

Quick comparison

What Paperpile does well

Paperpile solved a problem nobody else took seriously for years: citing inside Google Docs without pain. Zotero and Mendeley grew up as desktop applications with Word plugins, and their Docs support arrived later and works at arm's length. Paperpile was designed the other way round. It connects to your Google Drive, it signs you in with your Google account, and the Docs plugin is the main event. If your department writes in Docs and your supervisor comments in Docs, that alignment is worth real money.

The library does what a reference manager should. You collect papers with the browser extension, which Paperpile advertises as "one click" from "hundreds of publisher sites including Nature, Science, Springer, ScienceDirect, Wiley," plus "Deep integration with PubMed, Google Scholar, ArXiv." You organise with folders and labels. PDFs live in your Drive, and the annotator lets you "Highlight what matters and capture your thoughts." On the Expert plan you also get "full-text PDF search," which is the feature that turns a folder of 400 papers into something you can actually interrogate.

Word is supported properly. The plugin runs on "both Windows and MacOS," inserts citations with Shift-Cmd-P or Ctrl-Shift-P, formats bibliographies automatically, and lets you put several references inside one citation. So the Google-first design does not lock you out of Word. The docs are candid about the seam: "Google Docs and Word use different field encoding methods, so the way we add citations to each also differs," which means a document moving between the two needs a conversion step.

Your data comes back out. Paperpile exports BibTeX, RIS, and "a machine readable JSON format" from Settings > Data and files > Export, and the BibTeX export is unusually configurable: you choose "between classical BibTeX format and the more modern BibLaTeX format," which fields to include, and which entry type preprints should use. For anyone with a LaTeX thesis waiting at the end of the project, that last detail matters more than it looks. Import works the same way through RIS or BibTeX, so moving in from Zotero or Mendeley is a file transfer.

Collaboration is a paid feature that actually exists. Expert includes "shared folders," and the marketing describes building "a shared group repository" where you "Share papers, notes, and ideas with your team." Mobile apps ship for Android and iOS.

The pricing is honest about being academic. "50% off for students, faculty, researchers, and eligible nonprofits" applies to the people who use this software, so the sticker price is not the price most readers of this page would pay.

If a full reference manager is where you are heading, our comparison with Zotero covers the free, open-source end of that market, and the Mendeley comparison covers the Elsevier end.

The style catalogue question: 8,000 against 30

This is the number everyone leads with, so it deserves an honest paragraph.

Paperpile supports "over 8,000 citation styles out of the box" and lets you upload your own CSL file if that is somehow not enough. AllCitations carries 30. On raw catalogue breadth the comparison is over before it starts, and if your target journal has a house style that exists only as a community CSL file, Paperpile can reach it and we cannot. That is the correct reason to choose Paperpile over us, and it is not close.

What a large catalogue does not give you is edition precision. A CSL repository is organised by style name, and the edition a given file implements is often buried in its metadata or simply inherited from whenever someone last updated it. When your instructor writes "APA 7th edition" on the assignment brief, "APA" in a dropdown of eight thousand entries is an educated guess.

We went the other way and built around edition pairs: APA 6 and APA 7, MLA 8 and MLA 9, Chicago 17 and Chicago 18 in both author-date and notes-bibliography, AMA 10 and AMA 11, and citation-sequence and author-date variants of both CSE and Vancouver. You can generate one source in two editions and read the difference directly, which is the fastest way to find out whether your department's style sheet is current.

The rest of the 30 are weighted toward the styles students struggle to find working implementations of: Bluebook, OSCOLA and AGLC for law, ACS for chemistry, CSE for the life sciences, ASA for sociology, APSA for political science, ASM for microbiology, AIAA for aerospace, Nature, and Deutsche Zitierweise alongside three Harvard variants. Thirty curated styles beat eight thousand for exactly one job, which is knowing that the file you used implements the edition you were asked for.

Where Paperpile falls short

None of this makes Paperpile bad software. These are the friction points that send people looking, and they are real.

There is no free tier. Zotero is free forever. Mendeley has a free tier. Paperpile gives you "Try Paperpile free for 30 days" and then asks for a card. For a PhD student across five years, the arithmetic is fine. For an undergraduate with one research paper this semester, a 30-day trial that expires before the next assignment is a trial, and the tool is a subscription.

Billing is annual only. The pricing page footnote is explicit: "All plans billed annually, taxes may apply." The "$4.15*/month" headline is the effective monthly rate on a yearly commitment, so the amount that leaves your account is roughly twelve times that at once. There is no month-to-month option to cover a single busy term. That single constraint rules the product out for a large share of the people who arrive at a comparison page like this one.

It is a Chrome product with other browsers in progress. The help centre states that Paperpile "is fully supported on Chrome for macOS, Windows, Linux, and Chrome OS" and on Chromium-based browsers including Edge, Brave, Opera, Vivaldi, Yandex, and Arc. Firefox and Safari get this line: "Dedicated extensions for Firefox and Safari are currently in beta." A dedicated Safari user on a university-managed Mac should read that sentence twice before paying for a year.

It requires a Google account, and only one. "You can only sign up to Paperpile with one Google account at a time." If you have a personal Google account and an institutional one, you pick. People who finish a degree and lose access to the university account learn what that constraint means at the worst possible moment.

The DOI default is a genuine trap. Paperpile's own Word documentation says that "for print articles, Paperpile does not show DOIs or URLs by default" unless you switch on "Always include DOI and URLs." APA 7 wants the DOI on a journal article whenever one exists, whether or not you read it on paper. So a correctly-configured tool can hand you a reference that is missing a required element, and the output looks perfectly clean while it does it. Check that setting before you check anything else.

Upload cap. "The current upload limit is 400 MB." Most PDFs are nowhere near that. Scanned archival material and supplementary datasets sometimes are.

What AllCitations does well, and where it falls short

Where it wins: one correct citation, in a named edition, in the next few minutes. Thirty styles, free, no sign-up, no install, no card, no trial clock. Paste a URL, DOI, or ISBN, pick the edition your instructor actually named, and copy the reference out. Nothing above needs a Google account or a Chrome extension.

Export and import both work, which matters specifically for this comparison. A bibliography leaves as BibTeX, RIS, or a Word document, and BibTeX and RIS come back in. Both tools speak BibTeX and RIS, so AllCitations is a reasonable front door to Paperpile: format your sources now, export RIS, import them when you decide the subscription is worth it.

Now the honest half, because a comparison page that only flatters its own product is worth nothing to the reader.

It is not a reference manager and is not becoming one. No library. No PDF storage, reading, or annotation. No full-text search. No folders, no labels, no shared folders, no mobile app. Nothing syncs, because nothing is stored.

No word processor plugin, in Docs or in Word. This is the structural gap, and it is the one Paperpile subscribers are paying to close. A generator hands you formatted text. It cannot insert a live citation field at your cursor, and it cannot reformat every citation in a 90-page document when your supervisor changes their mind about the style in week nine. If you are writing a dissertation, that feature alone justifies a subscription, and no amount of free will substitute for it.

Nothing is saved. No account means nothing stored on our side. Export before you close the tab.

Thirty styles is thirty styles, and Paperpile's custom CSL upload has no equivalent here. If your journal's style exists only as a .csl file someone emailed you, we cannot load it.

A generator is still only as good as its metadata. Publishers supply inconsistent data, and a wrong year or a title stuck in ALL CAPS survives any tool's formatting step. The checks worth running on any generator's output are in how to use an APA 7 citation generator, and they apply to Paperpile's output too.

Which one should you use?

Pay for Paperpile if you write in Google Docs and want citations that live inside the document. Pay for it if your bibliography will outlast this semester, if you want your PDFs annotated and full-text searchable in the same place you cite them from, if you are sharing sources with co-authors, if you need a style that only exists in the CSL repository, or if you want configurable BibLaTeX output feeding a LaTeX thesis. Take the 50% academic discount and the 30-day trial, and use the trial to confirm your browser and your Google account situation work before the annual charge lands.

Use AllCitations if you need a specific edition rather than a style name, if your style is one of the law or science ones that general tools implement badly, if you want output with no account and no install, if you are on Firefox or Safari, or if you want BibTeX or RIS to hand to a reference manager later. That is also the right answer when the honest scope of the job is nine sources and an evening.

Use Zotero if you want a real reference manager and do not want a subscription at all. Zotero is free and open source, and leaving it out of this comparison would be dishonest. The trade is that its Google Docs support arrived as a plugin, which is the exact gap Paperpile charges to fill.

The combination a lot of people land on is worth saying plainly: a reference manager for the library, and a generator for the one awkward source at 11pm that the extension refused to capture.
