Hall tracks how large language models describe your brand, products, and category when shoppers ask ChatGPT, Perplexity, Gemini, and Claude for recommendations. The platform surfaces which sources AI cites, where competitors get mentioned instead, and how answers shift over time. Built for marketing and SEO leads at consumer brands adapting to generative search, it turns opaque model outputs into a measurable visibility channel with prompt-level tracking and share-of-voice benchmarks.
