Set up this template
Check whether a supplied passage supports the exact claim before citing it.
What to provide
One claim and the source passage intended to support it; include qualifiers such as dates and sample size.
- Paste the relevant source passage and one exact claim.
- Distinguish an opposing fact from a fact the source never addresses.
- Revise the claim or find more evidence when support is missing.
Outputs and rules
support · choice
The relationship between a claim and its supplied evidence.
Assess the exact claim against the source. Lack of evidence is not a contradiction. Use contradicted only when the source establishes an incompatible fact.
- supported
- The source supplies the evidence needed for the whole claim.
- contradicted
- The source supplies a fact that is incompatible with the claim.
- not_stated
- The source does not establish the claim or its opposite.
Try different inputs
Normal input
A related finding is not evidence for an unmeasured outcome.
Source: The trial included 120 participants. After six weeks, the treatment group reported improved sleep quality. The study did not measure productivity. Claim: The trial showed that the treatment improves workplace productivity.
Ambiguous input
The qualifier most needs evidence; some is insufficient.
Source: Some participants reported improved sleep; no exact share was given. Claim: Most participants slept better.
Missing information
Without a passage, the claim cannot be assessed as supported or contradicted.
Source: Not provided. Claim: The trial included 120 participants.
Use the result
Keep supported claims linked to the passage. Send contradictions for correction and not-stated results for another source or a narrower claim.
Limits to keep in mind
This checks the passage you provide. It doesn’t open links or verify whether the source itself is accurate.
