Check that your sources say what you say they say
Claim check reads your document and flags claims that are unsupported, overstated or contradicted. The evidence check compares each sentence with the paper it cites. Source quality catches retracted papers, preprints and wrong DOIs.
Why use citation and claim checker
Two kinds of check
It tells apart “this source exists” from “this source supports your sentence”.
Comments in your text
Each issue appears as a comment on the sentence, with a suggested fix.
Source health
Flags retracted papers, preprints and DOIs that do not match the paper.
How it works
Run the checks
Open Review and run Claim check, evidence check or source quality.
Read the comments
Issues are labelled, for example “Unsupported” or “Source says less than this”.
Fix or dismiss
Add a citation, soften the claim, or dismiss the comment.
What goes in, what comes out
You give it
- Your document or a selection
- The papers it cites
You get
- Comments labelled unsupported, weakly supported, overstated, unverifiable, contradicted or misrepresented
- A list of sources with retraction, preprint and DOI problems
Good to know
- The evidence check needs the cited paper’s text or abstract; it cannot check sources it cannot read.
- It is a second reader, not a guarantee. Some issues will be missed and some flags will be wrong.
An example
You enter
“Social media use causes depression in teenagers (Author, 2019).”
WriteOrbit returns
Overstated: the cited study reports a correlation, not a cause. Suggested: “is associated with”.
Questions
More in the help center.
Does it check that a citation exists?
Yes, and separately whether it supports your sentence. A real paper can still be cited for something it does not say.
How does it know a paper was retracted?
From retraction flags in the scholarly index for that paper.
