Generate properly formatted APA, MLA, or Chicago style citations from your source details instantly.
APA is common in social sciences, MLA in humanities and literature, and Chicago in history and other disciplines. Each has distinct formatting rules for authors, dates, and titles.
Yes, an accurate publication year is an important part of a correctly formatted citation in all three styles.
Leave the URL field blank — the citation will be formatted as a standard print/publisher source instead of an online source.
No, citation formatting runs entirely in your browser using JavaScript. The details you enter are never transmitted anywhere.
This tool is built around a single primary author field. For sources with multiple authors, list them in the author field following your target style's convention for joining multiple names.
This tool generates full bibliography and works-cited entries. In-text citations typically use a shortened form (like author and year for APA) that you construct separately based on the full entry.
This tool generates properly formatted citations in three of the most widely used academic citation styles — APA, MLA, and Chicago — from the source details you provide. Enter the author, title, publisher, year, and optional URL, and get all three formats at once, ready to copy into your bibliography or works cited page.
While all three styles cite the same underlying source information, they format it differently. APA places the publication year immediately after the author's name in parentheses. MLA places the publisher and year toward the end of the citation, with less emphasis on the exact date for many source types. Chicago's bibliography style is similar to MLA but with its own specific punctuation and ordering conventions. This tool handles these formatting differences automatically based on the fields you provide.
Proper citation gives credit to original sources, allows readers to locate and verify the material you referenced, and is a fundamental requirement of academic integrity. Different institutions, publications, and disciplines require different citation styles, which is why having quick access to all three formats from the same source details saves time when you're not sure which style a particular assignment or publication requires.
If you're not sure which citation style to use, the safest approach is checking your assignment instructions, course syllabus, or target publication's author guidelines first, since instructors and journals are often strict about which style they expect. As a general pattern, social science papers lean toward APA, literature and language coursework leans toward MLA, and history or certain humanities fields lean toward Chicago — but these are conventions rather than strict rules, and the specific requirement from your instructor or publisher should always take precedence over the general pattern.
A few citation mistakes come up often enough to be worth calling out directly: mixing formatting conventions from two different styles within the same bibliography, omitting the access date for an online source that specifically requires one, and inconsistent author name formatting across multiple entries in the same document. Generating each citation from a consistent source rather than hand-formatting every entry individually, as this tool does, helps avoid these kinds of small but noticeable inconsistencies across a longer reference list.
All citation formatting happens directly in your browser — the source details you enter are never sent to a server, logged, or stored anywhere.
Online and print sources are cited slightly differently across all three styles, which is why this tool treats the URL field as optional rather than required. When a URL is provided, the citation is formatted to reflect an online source, typically including the website or publisher name alongside the link. When left blank, the citation defaults to a standard print or publisher-based format instead, matching how a physical book, journal article, or printed report would normally be cited without any web-specific elements included.
For a research paper citing many sources, generating each citation individually and keeping them organized as you go — rather than trying to reconstruct a complete bibliography from memory at the end — saves significant time and reduces the chance of a missing or inaccurate entry. A simple approach is generating and copying each citation into your document's reference list immediately after using that source, rather than batching all the citation work for the very end of the writing process, when source details are harder to track down accurately and easy to misremember.
While this tool handles the formatting rules automatically, the accuracy of any generated citation still depends entirely on the accuracy of what you enter — a misspelled author name or wrong publication year will carry through into an otherwise correctly formatted citation. For high-stakes academic work, it's good practice to double-check generated citations against your institution's specific style guide or a dedicated style manual, since some fields and instructors apply additional formatting requirements beyond the general style conventions this tool follows.
Citation styles aren't fixed forever — each one is periodically revised by its governing body, and the specific formatting rules can shift meaningfully between editions. APA's 7th edition, MLA's 9th edition, and Chicago's 17th edition (the versions this tool targets) each introduced changes from their respective previous editions, affecting details like how many authors to list before using "et al." or how URLs are formatted. If you're citing sources for a specific publication or institution, it's worth confirming which edition they expect, since an older or newer edition can have subtly different formatting conventions from the ones used here, and using the wrong edition's rules can cost points on an otherwise well-researched paper.
