The AI Visibility Index
When buyers ask an AI assistant which software to use, the answer names a few vendors. This index measures who actually gets named across four engines, per category, run by run, and labels every source the engines cited by who owns it. No editorial picks and no pay-to-place, just dated measurements, published raw and re-measured monthly.

How it works. Real buyer prompts, run repeatedly in fresh sessions on both engines. We count who each answer names and record every source it cites, and the full method is on how we check. Why trust a measurement company’s index? Because you don’t have to trust it. Every category page links its raw runs for download and prints the prompts in full. Ask an engine one of them today and the list will come back different. We publish the archive rather than promise a repeat.
For the market-wide picture, see the study behind this index: State of AI Software Recommendations, how unstable and contradictory the AI shortlist is across four engines.
