Product Analytics: AI Visibility Ranking

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.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.

Just below the cutoff: Matomo (4.9), BigQuery (3.8), Contentsquare (3.6), RudderStack (3.2), Snowplow (2.9). 52 brands were scored in this category; the leaderboard shows the top 15.

Visibility Score: position-weighted presence across all measured answers, 0 to 100. A score of 100 means the brand was the first recommendation in every answer. Every point in a trend line is a live monthly measurement; there is no modeled or backfilled history. Full methodology.

Openness 16/100: the share of this category's recommendation weight not held by the leader.
