Pick a category and see what ChatGPT, Perplexity, Gemini and open models each recommend, and how much they disagree. This is honest, DOI-backed measurement, including the run-to-run variance most AI-visibility trackers quietly hide.
Each engine's #1 pick for this category. When these differ, "the best X" has no single answer, it depends entirely on which AI the buyer asks.
Tools this category's engines barely name, the opportunity space, and the vendors most anxious about it.
The domains AI answers pull from (network-wide). If you want to be recommended, this is who you need to be referenced by.
