Rank Prompt on the free plan: it scored our AI visibility at zero, and by hand we found citations on two of eight questions

Before we opened an account we asked Perplexity and Google AI Mode eight questions our readers ask, and wrote down every source they cited. Then we let Rank Prompt run its free report on the same site. It said zero percent, on nine questions it wrote itself. Both results are correct, and the gap between them is the whole product: an AI visibility tool measures the questions it chooses, and the free plan chooses questions a small site cannot win.
