Search vs. Store: AI App Search Demand vs App Store Rank vs Web Traffic (US, 2026)

One row per major AI app joining three independent popularity signals: Google search demand (Trends, anchor-normalized to ChatGPT=100 and bucketed into coarse tiers), best US App Store / Google Play chart rank, and SimilarWeb estimated monthly web visits. Two cross-sectional US snapshots (2026-07-01 and 2026-07-26) of 40 curated AI apps. Headline finding: search demand and web traffic broadly agree with each other, but App Store rank is the outlier — scrambled by distribution, not demand.
