CiteGenie is an APA citation generator and ACS citation generator built for students who need references that hold up to a TA's red pen. Psychology. Chemistry. Biology. Education. Health sciences. The discipline doesn't matter much; the format rules do. The citation checker catches missing authors, busted DOIs, and the small formatting slips that pull a paper down half a grade. Drop a snippet into the citation find source tool and it traces the line back to the original paper. Every result is citation verified against live academic databases. OpenAlex, Crossref, Semantic Scholar, PubMed, arXiv. 250M+ works between them.

Searching 250M+ scholarly works across 5 academic databases — in parallel, on every query

ACS CITATION GENERATOR APA CITATION GENERATOR

ACS, APA & MLA Citation Generator

Eight styles. Every source type. Paste a URL, DOI, or ISBN. You get a clean reference back in seconds. ACS, APA 7, MLA 9, Chicago, Harvard, AMA. The APA citation generator handles the things APA actually cares about. Author-date in-text format. Hanging indents. The DOI rules that changed in APA 7. And the 1/2/3+/21+ author-list quirks that trip most tools.

CITATION FIND SOURCE

Find the Source Behind Any Text

Paste a sentence. Get the paper it came from. The citation find source tool searches five academic databases in parallel and pulls back the original publication, usually inside a few seconds. Direct quotes work. Paraphrased lines work too. Handy for the moment a friend sends you a screenshot with no citation attached and asks where it's from.

CITATION CHECKER & VERIFY

Citation Checker — Verify & Correct References

Drop a reference into the citation checker. It runs against the actual record in academic databases. Missing author? Flagged. Page range wrong? Flagged. Style mismatch? It reformats to whatever you asked for. The whole point is catching the things a TA would circle in red, before the TA sees it.

Citation Check
Vaswani, A. (2017). Attention is all you need. NeurIPS.
Missing co-authors (8 total)
Volume/page numbers absent
Year and title correct
Corrected APA 7:

Writing Review
The model was very unique and showed alot of promise for future applications in the field of computational linguistics.
grammar "very unique" → unique
clarity "the field of…" → computational linguistics
WRITING ASSISTANT

Improve Academic Writing Quality

Paste a draft. Each suggested edit lands as one bullet you can accept or reject. Grammar. Tense drift. Dead-weight phrases. Topic sentences that don't actually open the paragraph. It's tuned for academic prose, so it won't try to flatten your methods section into LinkedIn English. Nothing changes until you click accept.

VERIFY SOURCE

Verify Every Cited Claim in a Paper

Upload a paper. The reading assistant pulls every cited claim automatically and checks each one against the source it points to. Misattributions. Broken refs. Claims the cited paper doesn't actually support. All surfaced in a single view. No more flipping back to the bibliography halfway through a read. You also get a short summary up top with the thesis and the headline findings.

82% AI-Generated Filler phrases detected
AI DETECTOR

Detect AI-Generated Text, Sentence by Sentence

Paste your text. You get one overall score from 0 to 100, plus a sentence-by-sentence breakdown. Red for likely AI. Amber for mixed. Green reads human. Hover any sentence and you see the specific reason it tripped. Filler phrase. Flat rhythm. Generic example. Built on DeepSeek V3.

Plagiarism Checker
Transformer attention scales quadratically with sequence length in standard implementations. Modern variants reduce this to O(n log n) (Vaswani et al., 2017).
Missing citation Cited — not supported + Find source
PLAGIARISM CHECKER

Audit Every Citation Before You Submit

Two checks per sentence in your draft. Does this claim need a citation? And does the cited source actually support what you said? Paywalled paper? Drop in the PDF and the verifier reruns against your copy. You get a per-sentence integrity score and a fix-it button next to each problem.

The in-text author-date citation. And the full reference list entry with a hanging indent, italicized journal title, and the right author-list rule for whatever you've handed it. One author. Two. Three to twenty. Twenty-one or more. They all format differently. APA cares.
APA 7, APA 6, MLA 9, MLA 8, Chicago (Author-Date), Harvard, AMA, ACS. That covers most of what humanities, social sciences, and STEM coursework actually asks for. If your professor wants something stranger, flag it on the contact page and we'll look at adding it.
The Citation Generator is free. No limits. No account. The AI features run on credits. That's Citation Checker, Find Source, and Writing Assistant. You get 10 free on sign-up and 3 more each day you log in. Top-ups are one-time payments. No subscription. Full pricing here.
Yes. CiteGenie searches every major academic database in one query. Crossref, Semantic Scholar, arXiv, OpenAlex, PubMed.
