This guide walks the top six in the order the mid-market standing puts them, with what the models said for and against each, in their words. Amplitude leads at 30% of first choices, and the standing is contested.

## Questions the record answers

**Which product analytics platform do AI models name first most often?** Amplitude, in 30% of first choices for a mid-market B2B company in the September 2026 Edition, from 62 labels. The standing is contested: the models did not settle on one product.

**Does the answer change with the size of the company?** Small business: PostHog at 43%. Mid-market: Amplitude at 30%. Enterprise: Amplitude at 49%. Each standing is computed within its segment and never pooled.

**Which framing changes the answer?** The direct, paraphrase, budget and scale framings count toward share. The product named first differs by framing: direct Amplitude; paraphrase Mixpanel; comparative Amplitude; budget-constrained PostHog; scale-constrained Amplitude; negative PostHog. The table above has the counts.

**How stable is one answer?** Asked again with nothing changed, the models moved their own first choice 66% of the time across the repeat sample; This category was in the repeat sample: asked again with nothing changed, the leader's share moved 2 points and the leader changed to Mixpanel.

**Where do the answers come from?** Four of the twelve models return sources. Their 19 answers here cite 183 pages; the sites cited most are amplitude.com, learn.g2.com, userpilot.com. The category page lists them all.

**Can a vendor pay to be on this list?** No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
