Citation Verification

Submit a claim for assessment

1. Enter one specific factual claim in the claim field.
2. Paste the relevant source text or evidence excerpt into the supporting evidence field.
3. Submit the form and wait for the assessment.
4. Review the verdict, rationale, and any evidence excerpt returned.
5. Compare the assessment with the original source before using it in a decision or publication.

The interface accepts claims up to 2,000 characters and evidence up to 12,000 characters. Supply evidence relevant to the exact claim rather than a broad collection of unrelated text.

What the verdicts mean

Supported

The supplied evidence directly supports the material parts of the claim.

Unsupported

The supplied evidence does not support the claim. That is not, by itself, proof that the claim is false.

Contradicted

The supplied evidence directly conflicts with a material part of the claim.

Uncertain

The evidence is insufficient, ambiguous, or mixed.

Review the rationale and excerpt

The rationale explains the assessment. The evidence excerpt, when returned, identifies a relevant portion of the supplied text. If no exact excerpt is returned, review the complete evidence manually. An excerpt is not a substitute for checking the original source and its context.

Important limitations

• The assessment is AI-generated and may be wrong.
• The result is limited to the evidence supplied; it does not establish that the evidence is authentic, current, or complete.
• For high-impact claims, verify the original source and seek appropriate expert review.
• A verdict should not be treated as ground truth or as a replacement for human judgment.
