In AI visibility tooling, sentiment is what separates a useful mention from a damaging one. A model that mentions your brand in the context of "great pricing" is doing different work than one that mentions you with "common complaints". Tools like Bluefish and Otterly.AI surface this by classifying the surrounding language with a small NLP step on top of the citation tracker.
