How are you currently measuring your brand's visibility in AI search?

With ChatGPT, Gemini, Claude, Perplexity, and other AI engines increasingly being used to discover information, I'm curious how marketers and SEO professionals are currently tracking where their brand appears, which competitors are mentioned, and which sources AI engines cite.

I'm building RankStacky to help answer these questions. We're currently in Alpha, and I'd love to hear what metrics or insights would actually be useful to you when monitoring AI search visibility.

What would you want RankStacky to tell you that traditional SEO tools don't?
