Citation Machine: Free APA, MLA & Chicago Generator

Anyone who’s wrestled with a bibliography knows the feeling — deadline looming, sources to format, fear of a misplaced period costing a grade — and Citation Machine promises to turn raw URLs and book titles into formatted citations in seconds. This guide walks through how to use it for APA, MLA, Chicago, and Harvard styles, what the free version can and cannot do, and how it stacks up against tools like MyBib, Scribbr, and Purdue OWL.

Developer: Chegg ·
Free Version: Available with limitations ·
Supported Styles: APA, MLA, Chicago, Harvard, and thousands more

Five key facts, one pattern: Citation Machine is a broad, well-maintained tool with strong style coverage, but important details like exact pricing and accuracy benchmarks remain opaque.

What is Citation Machine?

Citation Machine is an online citation generator developed by Chegg, designed to help students and researchers create correctly formatted bibliographies and in-text citations. It supports thousands of citation styles, including the major ones: APA, MLA, Chicago, and Harvard (Citation Machine official site). For citing historical figures like William Shakespeare, Citation Machine can generate accurate MLA citations. The tool offers both free and premium tiers, with the free version limited in daily citations and some advanced features locked behind a subscription.

How does Citation Machine work?

• Users select a source type (book, website, journal article, etc.) and enter identifying information like a URL, ISBN, or DOI.
• The tool searches databases and auto-fills citation details, which users can then review and edit before generating the final citation (Citation Machine Harvard guide).
• Citations can be exported to Word, PDF, plain text, or copied directly to the clipboard.

The trade-off: the tool’s auto-fill saves time, but users must manually verify every field — the system makes occasional errors, especially with less common source types (Yomu AI accuracy analysis).

Who owns Citation Machine?

• Citation Machine is owned by Chegg, an education technology company that also operates textbook rental and homework help services (Trinity University Coates Library).
• Chegg acquired the tool in 2018, integrating it into its larger suite of academic support products.

The implication: Citation Machine benefits from Chegg’s scale and ongoing investment, but is also subject to the company’s overall subscription strategy. Some features that were once free are now behind the premium paywall.

How do I generate citations with Citation Machine?

Generating a citation takes about 30 seconds once you have your source information ready. The tool guides users through a straightforward step-by-step process.

How to cite a website in APA

1. Go to Citation Machine and select “Website” as the source type.
2. Paste the URL of the webpage into the search bar.
3. Click “Search” — the tool attempts to auto-fill details like author, publication date, and title.
4. Review all fields manually and make corrections as needed.
5. Choose APA from the style dropdown and click “Create Citation”.

How to cite a book in MLA

1. Select “Book” as the source type.
2. Enter the book’s ISBN, title, or author name into the search box.
3. The tool locates publication details and fills in the form.
4. Switch the style dropdown to MLA and review the auto-filled information.
5. Click “Create Citation” to generate the MLA-formatted entry. Similarly, citing a biography like that of Marie Curie is straightforward.

How to export citations

• Once a citation is generated, users can copy it directly to the clipboard.
• Export options include Microsoft Word (.docx), PDF, and plain text formats.
• Creating a free account allows users to save citation lists for later access or export.

What this means: the tool excels at common source types — websites, books, journal articles — but requires more manual effort for unusual or complex sources.

Is Citation Machine free?

Citation Machine offers a free tier with clear limitations. For casual users, it’s a no-cost solution; for heavy academic users, the premium plan becomes necessary.

What are the limitations of the free version?

• Free users are limited to a certain number of citations per day (exact number varies and is not publicly disclosed) (Trinity University Coates Library).
• The interface includes advertisements, which can be distracting.
• Some advanced citation styles and features (like the plagiarism checker) are restricted to premium subscribers.

What features does Citation Machine Premium offer?

• Unlimited citations with no daily limit.
• Ad-free experience.
• Access to a built-in plagiarism checker.
• Advanced export options and the ability to create multiple project folders.

Pricing for premium is not fixed and varies by region; Chegg directs users to sign up for a yearly or monthly plan via its platform.

The pattern: the free version works as a “try before you buy” — sufficient for the occasional paper, but frustrating for students managing multiple courses where citations add up quickly.

How accurate is Citation Machine?

Accuracy is the make-or-break factor for any citation tool. Citation Machine generally produces reliable output, but it’s not flawless.

Does Citation Machine produce correct APA citations?

• According to a 2024 comparison by Yomu AI, Citation Machine gets APA style right most of the time for common sources like books, articles, and websites (Yomu AI automatic APA citation tools comparison).
• Errors most commonly stem from incorrect input data — if the user enters a wrong URL or incomplete metadata, the citation will be wrong.
• The tool occasionally misidentifies author names or publication dates from auto-fill results.

Is Citation Machine accepted by universities?

• Yes, universities accept citations generated by any tool as long as the output follows the correct style guidelines.
• However, most university citation guides, including Purdue OWL, emphasize that students should manually verify every generated citation against a style manual.
• The tool itself includes a disclaimer encouraging users to review auto-filled data for accuracy.

The trade-off: speed versus precision. For high-stakes submissions like theses or grant applications, manual double-checking against the official APA manual remains the safest route.

How does Citation Machine compare to other citation generators?

Five major tools, one comparison: Citation Machine competes in a crowded field with MyBib, Scribbr, Purdue OWL, and others. Each has distinct strengths and weaknesses.

Citation Machine vs MyBib

• MyBib is entirely free with no advertisements and claims support for over 9,000 citation styles, including APA 6 and 7, Chicago, Harvard, and MLA 7 and 8 (MyBib official site).
• Citation Machine offers a broader set of premium features (plagiarism checker, project folders) but restricts daily use on the free tier.
• MyBib’s interface is simpler and faster to navigate, while Citation Machine can feel busy with ads and multiple screens.

Citation Machine vs Scribbr

• Scribbr offers a free citation generator that supports APA, MLA, Chicago, and Harvard, with a key differentiator: citations are verified by expert editors (Scribbr citation generator).
• Scribbr’s premium service includes proofreading and plagiarism checking, but the citation generator itself remains free.
• Citation Machine has a longer track record (since 1999) but Scribbr is perceived as more academically rigorous due to its human verification layer.

Citation Machine vs Purdue OWL

• Purdue OWL is a free educational resource (.edu domain) offering comprehensive style guides and examples, but it does not auto-generate citations (Purdue OWL official site).
• Citation Machine automates the formatting that Purdue OWL teaches manually.
• For learning how citations work, Purdue OWL is superior; for producing a formatted list quickly, Citation Machine wins.

Frequently asked questions

For students overwhelmed by citations, Citation Machine offers real time savings — but that convenience comes with a trade-off in accuracy that demands human oversight. The best approach: use the tool to generate a draft bibliography, then cross-check each entry against the official style guide or a resource like Purdue OWL (free educational citation guides). For the student who writes five papers a semester, the choice is clear: Citation Machine’s free tier gets the job done, or switch to MyBib for unlimited no-cost citations with fewer distractions.
