Paste a source and an answer. Inspect sentence-level text matches and number differences, then record your own review.
Material to inspect
This is a text-comparison aid, not a factual verdict. Paraphrases and semantic contradictions require human review.
Evidence worksheetTEXT HEURISTICS
Evidence over eloquence
Fluency is a beginning.
Inspection is a practice.
A confident sentence can hide a missing source, an altered number, or a reversed condition. Make the comparison visible and keep judgment in your hands.
Read the field guide ↗Check the details
Surface numbers absent from the matched source and differences in negation. These are review signals, not proof of error.
Record your judgment
Mark each sentence as supported, needs review, or unsupported. Export the evidence worksheet with your annotations.
A few good questions
What the worksheet can tell you.
Does a high match mean a claim is true?
No. Matching wording only means the text is similar. Source accuracy, attribution, omitted context, and the meaning of a paraphrase still need human judgment.
Can it catch hallucinations?
It can surface weak wording matches, number differences, and possible negation differences. It cannot reliably detect all hallucinations or semantic contradictions.
Why are review labels editable?
Automatic checks are fallible. Your human assessment is stored separately from the automated signals and is included in the export.
