Visibility tells you whether AI mentions you; Brand Perception tells you how. It's a qualitative read of the way AI platforms describe and position your brand when asked about it directly. The strengths they reach for, the considerations they raise, and the weaknesses they flag.
The tone follows the balance of those: a brand AI consistently frames as "premium and reliable" reads very differently from one painted as "affordable but basic" or "a dated incumbent", and that framing shapes a buyer's impression before a human ever weighs in.
Because it's drawn from branded queries across multiple engines, it surfaces disagreements too: ChatGPT might emphasise your value while Claude leads with a caveat. Tracking perception over time shows whether your narrative is improving, and where a specific engine has picked up a description you'd want to correct.
