Free reference check, no account
Are your references real?
Paste up to 20 references. Each one is looked up in Crossref (with the Retraction Watch database), PubMed and Europe PMC: does it exist, is the DOI right, has it been retracted or corrected? Free, no sign-up.
Real is not the same as right. A free account adds the Citation Truth Check: upload the whole manuscript and see whether each cited paper actually supports the sentence you cite it for, whether every in-text number matches your list, and get a Verified References certificate for your guide or journal.
Create a free accountA "verified" reference exists and is not retracted. It does not show that the paper supports your sentence. Nothing you paste is stored; we keep a count of checks per network to enforce the daily limit.
