01
Which paper?
An exact DOI match is labeled separately from an author-year or reference candidate. Candidate titles must be confirmed by the user.
Free citation checker
Does the paper you cited support your claim?
Compare one manuscript claim with one cited paper. The checker shows the paper it resolved, the source text it could access, the exact passage behind the assessment, and the limits of that evidence.
Citation evidence workspace
One claim, one cited source, one inspectable evidence record.
Paste the sentence, or the whole paragraph and pick the sentence to check. The checker compares it with retrieved source text; it does not decide whether the claim is universally true.
Recommended for an exact paper match
A DOI is resolved directly. Without one, the tool returns a candidate that you must confirm from the title and authors.
Data boundary: the claim and reference are sent to Anthropic under commercial API terms and cached by Manusights for up to 24 hours. Raw text is not emailed, placed in analytics, saved in tool history, or published through a share link.

What the record proves
An inspectable trail, not an unexplained score
The checker separates four questions that ordinary AI answers often collapse. Each part appears in the result and the downloadable record.
02
What text?
The result states whether the evidence set was an abstract alone or an abstract plus eligible open-access full text.
03
Which passage?
A support assessment is published only when the returned quotation can be matched verbatim against retrieved source text.
04
What follows?
The interpretation and optional rewrite stay bounded to that passage. They do not certify the paper, the manuscript, or the claim as universally true.
Interpretation boundary
What the checker can and cannot answer
Can answer
Does the retrieved text of this resolved or candidate paper support this specific sentence as written?
Can qualify
Does the claim add causality, universality, mechanism, population scope, or certainty that the retrieved passage does not establish?
Must abstain
When no paper can be resolved, source text is unavailable, or the model cannot return a passage that matches the retrieved text.
Cannot answer
Whether the claim is universally true, the study is methodologically sound, the full literature agrees, or the manuscript is ready to submit.
