## Evidence and limitations
The AI form accepts 50,000 characters and analyses the first 15,000. Request limits apply. The separate source-overlap form completed a functional request; that is not an accuracy benchmark. No unrun benchmark results are published. Empty result slots require a person run.
Archived research, comparison and benchmark listings are noindexed.
