How it works
Paste any content and the checker scores each sentence on seven factors: specific numbers, dated references, named sources, named entities, length window (15-35 words), declarative assertions and hedged language. The result is a 0-100 likelihood score per sentence - the sentences most likely to be lifted into an answer.
Why sentences, not paragraphs
- Assistants passage-extract at the sentence level and use the surrounding context only as a disambiguator.
- A hedged claim gets discounted even if the rest of the paragraph is tight - the extractor can't tell the hedge apart from the claim.
- The extractor loves the 15-35 word window - long enough to carry the claim and the evidence, short enough to lift without re-parsing.
The rewrite pattern
For every sentence scoring under 55, pull it out and ask: where's the number, where's the source, where's the declarative verb? Pair this tool with the Fact Density Analyzer and the Passage Optimizer. Full playbook: how to write content AI assistants cite.
