`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.

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.
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.
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.
