What this tool does
A Chicago citation generator formats a source — a book, journal article, chapter, or website — according to The Chicago Manual of Style, the standard for history, the humanities, and much of the social sciences. Chicago is unusual among citation styles because it is really two systems: notes-bibliography, which cites with numbered footnotes and a bibliography, and author-date, which cites with parenthetical (Author year) references and a reference list.

What is a Chicago citation generator?
A Chicago citation generator formats a source — a book, journal article, chapter, or website — according to The Chicago Manual of Style, the standard for history, the humanities, and much of the social sciences. Chicago is unusual among citation styles because it is really two systems: notes-bibliography, which cites with numbered footnotes and a bibliography, and author-date, which cites with parenthetical (Author year) references and a reference list.
That split is exactly what makes Chicago fiddly by hand: the same source is punctuated differently in a footnote, in the bibliography, and in an author-date reference list — commas versus periods, first name first versus last name first, parentheses around publication details or not. This generator reads whatever identifies your source and produces all the forms in one pass, so you can use whichever system your instructor or publisher requires.
Notes-bibliography vs author-date — which do you need?
Notes-bibliography is the classic Chicago system used in history, literature, and the arts: superscript numbers in the text point to footnotes or endnotes, and a bibliography at the end lists every source alphabetically. If your assignment says "Chicago footnotes," this is the one.
Author-date is common in the sciences and social sciences: in-text citations look like (Smith 2024, 15) and point to a reference list. The formats differ mostly in how the year is placed. When in doubt, check your syllabus or the journal's author guidelines — and since this tool outputs both, switching costs nothing.
From one citation to a finished paper
A citation generator solves one source at a time; a real paper needs dozens, formatted consistently and updated every time you add or cut a source. Huggle keeps your bibliography alongside the document itself — generate citations here, then continue in Huggle to build the essay or thesis around them, with footnotes and bibliography managed together.
The generator is deliberately conservative: it formats only the details present in your input and omits fields it can't verify rather than inventing page numbers or publishers. Always check the result against the source before submission.

Frequently asked questions
- Is this Chicago citation generator free?
- Yes. Generating and copying Chicago citations is free and requires no account — you get a number of free runs per week. Signing up for Huggle adds unlimited generations, a saved bibliography, and the AI workspace to write the paper itself.
- Does it do both footnotes and author-date?
- Yes. Every result includes the notes-bibliography forms (bibliography entry plus numbered footnote) and the author-date forms (reference list entry plus in-text citation), so you can use whichever system your course or publisher requires.
- Which edition of the Chicago Manual of Style does it follow?
- The 18th edition. If your program or publisher still specifies the 17th edition, check its local guidance because punctuation and source-treatment details can differ.
- How is Chicago different from Turabian?
- Turabian is a student-oriented version of Chicago style with the same citation systems — notes-bibliography and author-date — plus formatting rules for papers and dissertations. Citations generated in Chicago style are valid Turabian citations.
- What can I paste as input?
- Anything that identifies the source: a URL, a DOI, the title plus authors and year, or an existing BibTeX entry you want reformatted. The generator never invents missing details — the more you provide, the more complete the citation.
- Can Huggle write the rest of my paper?
- Yes. Huggle is an AI workspace that produces finished, editable documents — essays, theses, and research papers. Generate citations here, then continue in Huggle to build the full bibliography and the document around it with every frontier model under one subscription.
