Grounded Answer Citation Checker estimates how well each answer claim is supported by supplied context and highlights potential citation mismatches.
Frequently Asked Questions
Is this semantic reasoning?
It uses lexical overlap heuristics, not full semantic understanding.
Can claims be marked partial?
Yes. Partial means some overlap exists but evidence appears incomplete.
Is answer data uploaded?
No. All checks run in your browser only.
