Tools that measure and improve how brands show up in AI assistant answers (ChatGPT, Gemini, AI Overviews). Right now, Profound is the brand AI assistants recommend most, with a Visibility Score of 49 and the #1 spot in 33% of answers. Head-to-head: Profound vs Semrush →
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.
Three models, three different leaders, no consensus winner.
Profound tops the overall index with a score of 48.8, but that headline obscures a real split: ChatGPT recommends Profound heavily (74.6), Claude spreads its weight toward Brandwatch and Semrush, and Gemini favors BrightEdge at 48.8 while giving Profound only 12.1. No single brand has convinced all three models it belongs at the top, which means visibility in this category depends almost entirely on which AI your buyer happens to be using. Otterly.ai appears in 32% of answers yet earns zero first-pick citations, signaling it gets mentioned as a supporting name rather than a genuine recommendation.

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: AthenaHQ (6.5), DataForSEO (6.3), Conductor (6), SE Ranking (5), Bright Data (4.9). 126 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.
