Free AI Citation Checker Every Reference, Verified Against Real Records
AI writing tools sometimes invent references that look completely real. Paste your reference list and this checker verifies every entry against trusted open scholarly databases like Crossref and Semantic Scholar, covering hundreds of millions of records. Each reference gets a clear verdict, the real record when one exists, and a corrected citation you can copy in seven style outputs.

How to verify AI-generated references in three steps
Paste your reference list
One reference per line, a numbered list or a whole pasted bibliography all work; the splitter handles wrapped lines and hanging indents. Up to 100 entries go through in one run.
Trusted databases are checked
Each entry is resolved by DOI first, then searched by title, author and year across Crossref, OpenAlex and Semantic Scholar, with a short pause between lookups to stay polite to the public APIs.
Read the verdicts, fix the list
Verified, match found, DOI mismatch or verify manually: each row explains itself, shows the real record when one exists, and offers a corrected citation formatted in your style.
Why this AI citation checker is different
Trusted databases, not guesses
Verification runs against Crossref, OpenAlex and Semantic Scholar: hundreds of millions of scholarly records maintained for and by the academic community, the same indexes scholarly search is built on.
Built for AI-generated lists
Language models produce references that are perfectly formatted and confidently wrong. The checker is built around their failure patterns, including the most telling one: a real DOI attached to the wrong paper.
The DOI trap, caught
Every DOI in your list is resolved, and when it points to a different work than the entry describes, you see exactly what it really belongs to. A formatted-looking DOI is no longer proof of anything.
Corrected citations included
When a real record is found, the checker formats it into a clean reference in APA, MLA, Chicago, Harvard, IEEE or Vancouver, with italics that survive pasting into Microsoft Word or Google Docs.
Why AI invents references, and how to catch every one
A language model asked for sources does something subtly different from looking them up: it writes text that resembles the sources it saw during training. The result is a reference with everything in the right place: a plausible author team, a title that fits the topic, a journal that exists, a DOI in the correct format. Some of those references are real. Others are composites, stitched from fragments of many real papers into an entry that matches none of them. Both kinds look identical on the page, which is why re-reading a reference list catches almost nothing and database verification catches almost everything.
That check is what this tool automates. Each entry is verified against the most trusted open databases in scholarly publishing: Crossref, where publishers themselves register the metadata behind 160+ million DOIs; Semantic Scholar, the Allen Institute for AI's index of 200+ million papers; and OpenAlex, which extends coverage further still. A DOI in your entry is resolved first, because a DOI that points to a different paper than the one described is the single most reliable signature of an AI-invented reference.
The verdicts are deliberately honest about what a database lookup can and cannot prove. A verified entry is confirmed against the publisher's own metadata. But an entry that is not found is reported as exactly that, never as fabricated: citation databases under-represent books, chapters, theses, preprints and non-English venues, so absence is a reason to check manually, not a verdict of guilt.
Two things this checker is not. It is not an AI detector: it makes no claim about how your text was written. And it is not a citation formatter, although it borrows one: corrected entries come from the same engine as the citation generator, and if you need to cite the AI conversation itself, the AI citation generator covers ChatGPT, Claude, Gemini and the rest with the official style patterns. Once the references are verified, the TextPulse humanizer handles the prose around them.
