Citation Machine: Free APA, MLA, and Chicago Citation Generator

You’ve got a paper due, a stack of sources, and zero patience for formatting footnotes by hand. That’s where Citation Machine steps in — a free online tool that turns URLs, ISBNs, and DOIs into polished citations in seconds. Here’s how it works, what it costs, and when it’s worth upgrading.

Citations generated per year: over 1 billion ·
Supported citation styles: over 7,000 ·
Active users monthly: over 30 million ·
Years in operation: since 2000

Five key facts that define Citation Machine’s capabilities at a glance.

Editor’s note The premium price and export formats come from Citation Machine’s subscription page; free version limits exports to plain text.

How do I use Citation Machine to generate an APA citation?

1. Selecting the APA 7th edition style

   • Go to Citation Machine’s APA page and choose APA 7th edition from the style dropdown if it isn’t preselected.
   • For book or journal sources, use the tabs at the top to switch source types (Citation Machine Chicago page shows a similar interface).
   The upshot

   APA 7th edition is the default, so first-time users rarely need to change a thing — but double-check the edition before you copy.

2. Entering source details (book, website, journal)

   • Paste a URL, ISBN, or DOI into the search box. The tool auto-fills author, date, title, and publisher (Scribbr’s generator works the same way).
   • For websites, enter the URL and click “Cite.” The tool pulls metadata from the page (Citation Machine APA website instructions).
   • Manual fields let you correct or add missing information like a specific author or publication date (Purdue OWL recommends checking input carefully).
   What to watch

   If the tool can’t find a publication date, it may default to “n.d.” – verify against the actual source before submitting your paper.

3. Generating and copying the citation

   • Click “Cite” to generate the full APA reference list entry plus an in-text citation.
   • Copy the formatted citation to your clipboard or export it as part of a bibliography (Cite This For Me uses a similar copy workflow).

   The implication: a few clicks can produce a citation that looks correct, but Purdue OWL stresses you must check the generated citation against a style guide before including it in your final draft.

What citation styles does Citation Machine support?

APA, MLA, and Chicago styles

• These three are the core free styles. The tool walks you through each one step by step (APA page, Chicago page).

Harvard and AMA referencing

• Harvard is widely used in UK and Australian universities; AMA is common in medical fields. Both are included in the free tier.

Over 7,000 total citation styles

• Citation Machine claims to cover more than 7,000 styles (official site), including less common ones like ASA, IEEE, and Turabian.

The catch: with that many styles, maintenance may be uneven. Citation Machine’s terms note that style coverage can change without notice.

Is Citation Machine free to use?

Free tier features and limitations

• The free version generates APA, MLA, and Chicago citations without ads (example on the APA page).
• You can create unlimited citations per project, but you cannot export to Word or Google Docs without upgrading.

Premium subscription benefits

• Premium costs $9.99 per month and removes ads, adds one-click exports, a plagiarism checker, and a grammar scanner (subscription terms).

Comparison with other free citation generators

• MyBib is completely free with no ads (MyBib Chicago generator).
• Scribbr offers a free generator plus a paid proofreading service (Scribbr citation tool).
• QuillBot provides free APA, MLA, and Chicago citations (QuillBot citation generator).

The trade-off: if you only need APA/MLA/Chicago and you’re fine with manual copy-pasting, the free tier works. If you want Google Docs integration and plagiarism checking, the premium plan is one of the pricier options among competitors.

How do I cite a website in APA format with Citation Machine?

Entering the website URL

• Go to the APA website citation page, paste the URL into the field, and click “Cite.” (Citation Machine APA website tool)

Selecting the correct source type

• The tool often auto-detects the source type (news article, blog, government page). If it misidentifies, use the dropdown to correct it.

Reviewing and editing the generated citation

• Check that the author, date, title, and URL are correct. If the page lacks a date, Citation Machine will add “(n.d.)” – you can replace it with an access date (Chicago guide shows this rule).
• Purdue OWL warns to avoid vague page ranges and to designate the correct medium.

Why this matters: a missing date or wrong author can lead to a citation error that wastes points. Always verify against the original source.

How does Citation Machine compare to other citation generators?

Citation Machine vs MyBib

• MyBib is completely free with no ads and supports APA, MLA, Chicago, and 8,000+ styles (MyBib Chicago generator). Citation Machine’s free version limits exports.

Citation Machine vs Scribbr

• Scribbr offers a free generator that automatically looks up sources by title, URL, ISBN, or DOI (Scribbr generator). Its paid service includes expert verification of citations.

Citation Machine vs Purdue OWL

• Purdue OWL provides free style guides and examples but does not auto-generate citations. It’s a complement, not a direct competitor (Purdue OWL’s responsible use page).

The pattern: Citation Machine sits in the middle – it has a generous free tier but charges for convenience features, while MyBib gives everything away for free and Scribbr upsells editing.

What’s confirmed and what’s unclear about Citation Machine

“You can start citing books, websites, journals, and more in seconds.”

— Citation Machine official site (Chicago generator page)

“Select the source type, enter a URL for websites, or enter ISBN or title for books.”

— MyBib Chicago citation generator

“Check the information you input carefully because the generator’s output depends on that input.”

— Purdue OWL – Using Citation Machines Responsibly

Citation Machine saves time, but no automated tool is perfect. The biggest risk is trusting the output without a final check – that’s where points get lost. For the student who writes one or two papers per semester, the free tier with a manual double-check against Purdue OWL is perfectly adequate. For the heavy researcher who juggles dozens of sources and needs quick formatting, the premium subscription’s export functions and plagiarism check may justify the $9.99 monthly fee.
