Three styles, one form
APA is standard in the sciences and social sciences, MLA in the humanities and literature, and Chicago in history and some publishing. They differ in author formatting, where the date sits, and punctuation — this tool handles all three from a single set of inputs so you can paste whichever your assignment requires.
Always verify
This generator nails the common case, but citation styles have many edge rules — multiple authors, corporate authors, editions, missing dates, DOIs. Treat the output as a fast, accurate first draft and double-check anything unusual against your course style guide.
