Chicago style, defined by The Chicago Manual of Style, actually covers two distinct citation systems. Notes-Bibliography is the one most common in history, literature, and the arts: sources are cited with a numbered footnote or endnote at the point they're used, and a full bibliography lists every source at the end. Author-Date is the one common in the sciences and social sciences: sources are cited in-text as (Author Year), with a reference list matching those in-text mentions. The two systems format the same source differently and shouldn't be mixed within one paper — the first thing to get right with Chicago style is knowing which of the two your instructor, journal, or publisher expects.
Most citation generators will format whatever you paste in, whether or not the source is real. We check your reference against OpenAlex, Crossref, Semantic Scholar, PubMed, DBLP, and arXiv first, looking for independent agreement between sources, before handing back the formatted Chicago citation. If we can't confirm it, we tell you rather than silently formatting a source that may not exist.
Chicago style has two citation systems. Notes-Bibliography, common in history and the humanities, uses numbered footnotes or endnotes plus a bibliography. Author-Date, common in the sciences and social sciences, uses in-text parenthetical citations like (Author Year) plus a reference list. Both are defined by The Chicago Manual of Style.
Notes-Bibliography cites sources with a numbered footnote or endnote at the point of use, plus a full bibliography at the end; it's the norm in history, literature, and the arts. Author-Date instead cites sources in-text as (Author Year), with full details in a reference list; it's the norm in the sciences and social sciences. The two aren't interchangeable within one paper.
Paste in what you already have — the fuller the reference (title, authors, publisher or journal), the more reliably we can verify it against academic databases before formatting. A DOI included alongside the rest of the reference helps confirm the match; a bare DOI or URL with nothing else attached is the least reliable input on its own.

AccuraCite Now Has an MCP Server
AccuraCite now ships an MCP server for Claude, Cursor, and other MCP clients — the consensus verification engine, not a single tool call, exposed over MCP.
We Benchmarked AccuraCite's Citation Finder Against Raw AI — Here's What We Found
We tested AccuraCite's Find Citations feature against a naive AI answer and a naive title match, on claims about obscure, recent research. The grounded pipeline won by a wide margin.
What Is a Retracted Citation, and Why 'Verified' Doesn't Mean Safe to Cite
A citation can be 100% real, correctly matched, and still be a paper you shouldn't cite. Here's what a retraction is, how AccuraCite detects it across three databases, and two real cases that prove it works.
What Is DOI Verification, and Why a Real DOI Isn't Enough
A DOI that resolves isn't proof a citation is real. Here's what DOI verification actually checks, the ways a DOI can be wrong, and how to check one properly.
AccuraCite Catches 99.4% of Fake Citations — Here's the Leak-Free Benchmark
We tested AccuraCite against 918 real citations, including citations built specifically to be hard to catch. It caught 99.4% of the fakes.

How to Find Sources for a Claim When AI Can't Back It Up
Asking ChatGPT for a source often returns a hallucinated citation or a real paper that doesn't back your claim. Here's how to find sources that actually do.
Why AI Citation Checkers Get Fooled by Fake DOIs (And How We Fixed Ours)
A citation-verification tool told us a famous 2017 paper was published in 2025 by a fake publisher. Here's the real bug, and the fix AccuraCite shipped.

Did ChatGPT give you real sources? Here's how to check every citation in your own paper before you submit it, in one pass instead of Googling each by hand.
Why 'Just Use an LLM with MCP Tools' Doesn't Solve Citation Hallucination
MCP lets an LLM call academic APIs directly. That sounds like it solves citation hallucination. It doesn't, by itself — here's the actual failure mode, with a real example.
