Generate accurate APA, MLA, Chicago, Harvard and IEEE citations from a URL, DOI, or ISBN. Free, no ads, no sign-up — every source verified against real databases.

`The free citation tool that checks your sources are real`
> Corroba is a free, no-ads citation generator that's actually accurate — every source is checked against real databases (Crossref, PubMed, OpenAlex), so it never invents one. It also verifies whole bibliographies, catches fake AI citations, finds free PDFs, and more.
> Hey Product Hunt 👋
> I'm Colin, and I built Corroba because every citation tool I've used felt *hostile*. EasyBib and its cousins bury you in ads and pop-ups, paywall basic APA, and dark-pattern you into subscriptions. And now ChatGPT will happily hand you a perfectly-formatted citation for a paper that doesn't exist.
> So I made the opposite: a citation tool that's free, clean, and — most importantly — **honest.**
> Corroba never invents a citation. Every source is pulled from real bibliographic databases (Crossref, OpenAlex, PubMed, Open Library), so it's grounded in a real record, not made up. Paste a link, DOI, ISBN, or title → get a correct citation in APA, MLA, Chicago, Harvard, IEEE, or any of 10,000+ styles.
> Then it goes further than a generator:
> - **Verify** — paste a bibliography and it checks every reference against real databases, flagging anything it *can't* find, that's mismatched, broken, or retracted. (Perfect for sanity-checking an AI-assisted paper.)
> - **Source quality** — tells you if a source is peer-reviewed, a preprint, or just a webpage.
> - **Integrity** — checks your writing against the sources you actually cited.
> - Plus little things I always wished existed: convert a citation between styles, find a *legal* free PDF of a paywalled paper, and an "explain this citation" mode that teaches you **why** it's formatted the way it is.
> Everything core is **free forever — no sign-up, no ads.** There's dark mode and a dyslexia-friendly font too.
> I'm a solo maker and this is very much a labor of love. I'd genuinely love your feedback, your best citation-tool horror story, and any styles or features you want me to add
How does the verification actually work when you paste a DOI — are you checking against Crossref in real time, or pulling from a cached database? Curious how often it misses something newer.
@emrahoizm
How does it actually verify sources against real databases under the hood, especially for obscure ISBNs or paywalled articles? Curious whether it's hitting CrossRef and OpenAlex directly or pulling from something else.

Finally a citation tool that actually pulls from real databases instead of guessing. Threw a messy DOI at it and got a clean APA entry in under a second, no sign-up walls.
