AI Sentiment
In one line
AI Sentiment captures the tone — positive, neutral, negative — of the passages where your brand appears inside AI answers, used to adjust raw citation numbers.
Going deeper
AI Sentiment fills in what raw citation counts cannot show. A single mention as 'a recommended solution' is not the same asset as a single mention as 'an option with drawbacks' — so the tone of the surrounding passage gets classified alongside the count.
It is especially useful as an early-warning signal. If citation rate holds steady but the negative share suddenly climbs, it usually means a bad fact has settled into the model or negative coverage has accumulated on external sources.
Measurement typically uses an LLM to classify the snippets, often with a human review pass. Automatic classification is noisy enough that for priority keywords and personas it pays to keep a human in the loop on the sentiment labels.
