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.
