Updated 2026-09-17 · 63 sampled answers · rolling 4-week window · methodology
Rankings are measured from sampled AI answers — never editorial, never paid. Orbator builds AI-visibility tooling; when Orbator itself appears in any category, it is measured by the same rules as everyone else.
Measured by Orbatormethodology owner Henrik Tellewindow ends Sep 17, 2026
Sample: 63 AI answers · Window: Aug 20, 2026 – Sep 17, 2026 (4-week rolling) · trend vs prior 4 weeks (56 answers)
Samples by engine: GEMINI 14 (last run Sep 7, 2026) · CHATGPT 14 (last run Sep 7, 2026) · CLAUDE 14 (last run Sep 8, 2026) · PERPLEXITY 14 (last run Sep 7, 2026 — stalest) · GROK 7 (last run Sep 7, 2026)
How these numbers are made: sampling design · prompt provenance · what counts as a mention · what we cannot see

Across 63 sampled AI answers from 5 engines, CoSchedule is recommended most often — appearing in 52.4% of recommendations, followed by Notion (46%) and Airtable (41.3%).
This is a measurement of share of voice across 5 AI engines — not an editorial pick. See the full ranking below.
Orbator asked Gemini, ChatGPT, Claude, Perplexity and Grok buyer questions about content calendar tools and sampled 63 answers between Aug 20, 2026 and Sep 17, 2026. Recommendation share counts the answers that recommended or listed a product, so a passing mention or a warning adds nothing to it. A category publishes once it holds at least 20 independently sampled answers in the window. Read the full methodology or download this ranking as CSV.

Reading the numbers: Share is a point estimate on 63 sampled answers, so each row also shows its 95% CI — the Wilson score interval around that share. When two products' intervals overlap, the gap between them isn't statistically meaningful at this sample size. First pick is the share of a product's recommending answers where it was named first, which separates “always mentioned” from “usually the top recommendation”. Full methodology.
