What the APA citation check finds

The most common formal rejection reason, visible before the journal finds it.

  • Orphan citations in the text with no entry in the reference list.
  • Unused entries in the list that are never cited in the text.
  • APA-7 formatting checked, in German and English.
  • Every DOI verified against Crossref for free.
  • Detects invented sources: AI articles that don't exist.

Every finding with location and fix

No vague feedback: each finding names the exact spot in the document, the problem and a concrete before/after suggestion you can apply. You also get your manuscript back as an annotated Word document with margin comments.

DOIs verified against Crossref

The DOI check runs against Crossref and is free. So it surfaces when a DOI doesn't resolve, isn't in Crossref or belongs to a different source than stated. Built on the proven DISIE citation engine (disie.online).

Frequently asked about the APA citation check

Which citation styles are supported?

APA 7 in German and English, including DOI verification via Crossref. Numeric/Vancouver styles are checked with limitations.

Is the citation check really free?

Yes. You can always download the APA-7 / Crossref check for free, no payment at all. Only the full report with all modules costs (9,00 €, solidarity price 4,50 €).

What is an orphan source?

A citation in the text with no entry in the reference list, or an entry that is never cited in the text. The check lists both directions with the location.

How is the DOI verified?

Every DOI is checked against Crossref: does it exist, does it resolve and does it match the stated source. That's how the check also catches invented sources.

What files can I upload?

Word documents (.docx). The check runs in 1–2 minutes, no account and no queue.
