Identifier detector: pull DOI, ISBN, PMID, and arXiv from text
One paste field. The detector extracts identifiers. This is the lead-in to the DOI checker or Quick Check, not the check itself.
Which job do you need?
I want APA generated from the DOI
That is a generator. Acurio does not format citations.
I want to see DOI, ISBN, PMID, or arXiv in the text
That is this field. Extraction, no registry lookup.
I want to know the DOI exists
That is the DOI checker, one click on.
What the detector does
It looks for DOI patterns, ISBN-13 (with checksum), labeled ISBN-10, PMIDs, and arXiv IDs. An arXiv DOI is counted as arXiv, not twice as a DOI.
No registry is queried. Existence and retraction live in the DOI checker and Quick Check.
A found DOI can be resolved in the DOI checker next.
Frequently asked questions
Does this check whether the DOI exists?
No. It only recognises that an identifier is in the text. Resolution is the DOI checker.
Is it free?
Yes. No account, no registry call.
Does it read PDFs?
No. Pasted text only. A PDF snippet pasted as text works; an upload does not.
