Generate properly formatted citations in APA, MLA, and Chicago styles. Enter your source details and copy the citation instantly — no account needed.
What Is a Citation Generator?
A citation generator is a tool that formats source information — author, title, publication date, URL, and other details — into a correctly structured citation according to a specific style guide. Instead of memorizing the punctuation rules for APA, MLA, or Chicago style, you enter the source details and the tool formats the citation for you.
Citation generators produce two types of output: a bibliography entry (the full reference that goes in your reference list or works cited page) and an in-text citation (the short reference that appears inside your text to point the reader to the full source). Both are based on the same source details — the format depends on the citation style you choose.
Multiple Citation Styles
Generates correctly formatted citations in APA 7th, MLA 9th, and Chicago 17th edition — the three most widely used styles in academic and professional writing.
Multiple Source Types
Supports websites, books, journal articles, and videos — each with the specific fields required by that source type. The form updates automatically when you change the source type.
Instant Copy
Copy any citation in one click — the selected style from the main panel or all three formats at once from the All Formats section below. No typing, no reformatting by hand.
Live Preview
Citations update automatically as you type — no submit button needed. You can see the formatted output change in real time as you fill in each field.
Why Proper Citations Matter
A citation does two things: it credits the original author or source for their work, and it gives the reader the information they need to find that source themselves. Missing or incorrect citations create several problems — in academic work, they can result in plagiarism penalties; in research publishing, they reduce the credibility of your claims; in web content, they affect how readers and search engines evaluate the trustworthiness of your information.
Formatting matters alongside completeness. A citation with the wrong punctuation, capitalization, or field order may be flagged by instructors or editors, even if all the information is technically present. APA, MLA, and Chicago each have specific rules about what information is required, in what order, and in what format — and those rules differ between source types as well as between editions of the same style guide.
For web content and SEO work, citations are also a credibility signal. Citing research, statistics, and external sources by linking to them improves the factual authority of your content and demonstrates to readers — and to Google's quality evaluation systems — that the claims in your content are supported by real sources.

What Citation Styles This Tool Supports
The Citation Generator currently supports the three most widely used academic and professional citation styles. Each style has different rules for field order, punctuation, italics, and what information is required for each source type.
Used In: Social Sciences, Psychology, Education, Business
APA (American Psychological Association) style places the publication year near the beginning of the citation, uses sentence-case capitalization for article titles, and italicizes book and journal titles. The 7th edition (2020) removed the publisher location requirement for most sources and standardized DOI formatting.
Used In: Literature, Humanities, Language Studies
MLA (Modern Language Association) style uses title-case for article and source titles, places the year at the end of the citation, and uses "Works Cited" as the bibliography heading. The 9th edition (2021) introduced the concept of containers — nested sources like journal databases or streaming platforms.
Used In: History, Arts, Archaeology, Publishing
Chicago style (University of Chicago Press) has two systems: Notes-Bibliography (used in humanities) and Author-Date (used in sciences). The tool generates the bibliography entry format used in the Notes-Bibliography system, which is the more common academic format for Chicago citations.
Used In: Sciences, Social Sciences, UK Universities
Harvard referencing is similar to APA in structure — author, year, title, source — but differs in punctuation, capitalization, and access date formatting. Harvard style is widely used in UK universities and in many science disciplines. A Harvard citation format is planned for a future update.
Source Types You Can Cite
Different source types require different fields. A website citation needs a URL and access date. A journal article needs volume, issue, and page numbers. A book needs a publisher and often a city. The tool shows the correct fields for each source type automatically when you change the selection.
| Source Type | Required Fields | APA | MLA | Chicago |
|---|---|---|---|---|
| Website / Web Page | Title, Author (if known), Year, URL, Publisher/Site name, Access date | Supported | Supported | Supported |
| Book | Title, Author, Year, Publisher, City (for Chicago) | Supported | Supported | Supported |
| Journal Article | Title, Author, Year, Journal name, Volume (Issue), Pages | Supported | Supported | Supported |
| YouTube / Video | Title, Channel/Author, Year, URL, Access date | Supported | Supported | Supported |
| PDF / Report | Title, Author, Year, Organization, URL | Planned | Planned | Planned |
| Newspaper Article | Title, Author, Date, Newspaper name, URL | Planned | Planned | Planned |
Common Citation Mistakes
Citation generators format the information you provide — but the quality of the output depends on entering accurate, complete source details. These are the most common mistakes that lead to incorrect citations.
Wrong Author Format
APA and Chicago require "Last, First" format. MLA also uses last name first. Entering a full name in the wrong order (First Last) produces a citation that fails the format check. For organizations as authors, enter the full organization name exactly as it appears on the source.
Missing Access Date for Websites
Online sources can change or be removed. APA requires an access date when the content is likely to change. MLA always requires an access date for web sources. Leaving this field blank produces an incomplete citation for online sources in both styles.
Using the Wrong Edition
APA 6th and APA 7th have different rules — publisher location is required in APA 6th but not in 7th. MLA 8th and 9th differ on container formatting. Always confirm which edition your institution or publisher requires before generating and copying a citation.
Citing a Secondary Source as Primary
If you found a statistic in one article that was originally published in another, cite the original source — not the article where you found it. Citing a secondary source as if you read the primary is misleading. Track down the original paper or dataset and cite that directly.
No Author Listed
If no author is listed on a website, use the organization name as the author. If no organization is identifiable, some styles allow moving the title to the author position. Do not leave the author field blank for a source that has one — missing the author changes the in-text citation format entirely.
Not Reviewing the Output
Citation generators format what you enter. If a date is in the wrong format, the URL is broken, or the title is missing capitalization, the output will be wrong even though the tool worked correctly. Always review the generated citation against the original source before using it.
How to Review Generated Citations
A generated citation is a starting point, not a finished product. These four checks take less than a minute and catch the most common errors before you submit or publish.
Verify Author Format
Check that the author name matches the required format for your style — Last, First for APA; Last, First for MLA; Last, First for Chicago bibliography. Confirm the name is spelled correctly and matches the source exactly. Multiple authors follow different rules in each style.
Confirm the URL Works
Paste the URL from your citation into a browser and confirm it still loads the correct page. URLs change. A citation with a broken URL is technically complete but useless to the reader. For sources likely to change, note the access date so the reader knows when you viewed it.
Cross-Check Against the Style Guide
Compare the generated citation against the official style manual or your institution's citation guide — especially for less common source types or unusual authorship situations. The generator follows standard rules but your institution may have specific requirements that override them.
Check for Plagiarism Before Submitting
Citations confirm you have credited your sources — but they do not guarantee the surrounding text is original. Before submitting academic or professional work, run the full document through the Plagiarism Checker to confirm the content around your citations is properly original and attributed.
