This feature is part of AI Visibility & Brand Mention Tracker Pro. In the free version the place where it lives shows a blurred sample of what it does and a button to get Pro.
AI sentiment rates how each answer describes your brand and every competitor: positive, neutral or negative, in any language. Being named is not enough if AI warns buyers against you; sentiment shows you when that happens.

Where you see it
- Results: the Sentiment field on each answer, and a Sentiment filter.
- Competitors: a Sentiment column for you and each competitor: Positive, Neutral, Mostly positive or Mostly negative.
- Suggestions: a Fix how [services] describe you suggestion when AI describes you negatively, quoting what it said.
How it works and what it costs
After each answer that mentions at least one brand, the plugin asks the AI service you chose for Pro work to rate it. That is one extra API call per such answer. You pick that service at the top of the Client report page, under AI service for Pro work.
In the free version
The Sentiment field on each answer is there with a PRO tag and a blurred sample value, so you see where it would show.
