AI visibility index
Which apps AI assistants recommend.
More product research now starts in a chatbot than in a search box. Ask ChatGPT, Claude, Gemini or Google for the best app in a category and a few names come back. Those names are the new shelf. People tend to explore in an assistant first and verify on Google after, so an app that never gets named is one the buyer never goes looking for. validcube runs the same buyer questions across five assistants and records which apps each one names.
01
The same questions, kept fixed
A set of real buyer questions, run across five assistants and kept identical between runs. Change the method and the version changes with it, so any movement is real rather than noise.
02
Independent
Not built by an app maker or an AI vendor, so the ranking can be honest even when it is unflattering. The full method is published.
03
Built for the shift
App discovery is moving from the store into the chat. This records who gets named on that new shelf, and is built to show how the answers shift as models change.
