Tools for understanding user behavior, funnels, retention, and feature adoption. Right now, PostHog is the brand AI assistants recommend most, with a Visibility Score of 84 and the #1 spot in 39% of answers. Head-to-head: PostHog vs Mixpanel →
These rankings are measured from what the three models know from training, not a live web search. When the models DO search the web, see which sources they cite. Methodology.
PostHog and Mixpanel are effectively tied at the top.
PostHog and Mixpanel sit within 1 point of each other, and neither has pulled away enough to call this settled. Claude is the interesting fault line: it scores Mixpanel at 90.8 versus PostHog at 81.7, while Gemini flips that preference hard in PostHog's favor at 87.5 against 77.1. Amplitude hangs in at 82% mention rate but rarely gets picked first, and Heap and FullStory are largely absent from the conversation that actually shapes buyer decisions.
