Compare Amplitude and Mixpanel across five buyer questions and four model providers. ## Key findings 1. PostHog was named first in 24 of 50 answers, ahead of Amplitude at 15 and Mixpanel at 11. 2. Amplitude and Mixpanel were named in all 50 recorded answers ; PostHog was named in 48. 3. The recorded prompt groups differ. PostHog was first in 9/10 startup-recommendation answers , while Amplitude was first in 9/10 comparison answers. 4. Google's sampled models named PostHog first in 9/10 answers. Perplexity's sampled models named Amplitude and Mixpanel first in 4/10 answers each, with PostHog first in 2/10. 5. One response per prompt-model pair makes this a snapshot, so a gap of one or two answers may not repeat. ## Chart: Product analytics, edition 2026-09 | Vendor | Answer share | Named first | | --- | --- | --- | | Amplitude | 100% | 30% | | Mixpanel | 100% | 22% | | PostHog | 96% | 48% | | Heap | 62% | 0% | | Pendo | 54% | 0% | | FullStory | 30% | 0% | | Google Analytics | 22% | 0% | | LogRocket | 20% | 0% | 50 answers. Edition source: https://www.memetik.ai/data/2026-09/product-analytics.json You are assessing software visibility in AI answers and need to know what the counts measure before you act on them. We help software founders and growth teams understand their products' measured visibility in AI answers. In the September 2026 product analytics sample, Amplitude and Mixpanel were named in every recorded answer and PostHog was named first most often, which tells you how each name appears in AI answers rather than which tool to buy. The detail sits in the prompts. PostHog was named first in nine of ten answers to the prompt asking which product analytics tool to recommend to a startup in 2026. Amplitude was named first in nine of ten answers to the prompt asking to compare the top options. We report the dated sample and the exact questions so you can judge whether a visibility comparison supports your conclusion. Your decision is how to interpret an AI-visibility comparison. Product-purchase decisions require separate evidence about your requirements and the products. ## What does this PostHog, Amplitude and Mixpanel comparison measure? It measures two things: how often each name appears in an AI answer, and how often it appears before any other tracked vendor. Our product analytics research compares mention frequency and first position for PostHog, Amplitude and Mixpanel across recorded buyer questions. A mention counts when the vendor's name or a known alias appears in the answer text. Answer share measures whether a tracked vendor appears in an answer. Named first records the earliest appearance among all 16 tracked vendors, even though this article compares three. The product analytics category tracks 16 products, of which 13 were named. This article selects three of them for comparison: PostHog, Amplitude and Mixpanel. You can read the full category in the [product analytics Index](https://www.memetik.ai/index/product-analytics). ## How often were PostHog, Amplitude and Mixpanel named in AI answers? Amplitude and Mixpanel were named in all 50 recorded answers. PostHog was named in 48. Amplitude and Mixpanel therefore share the highest answer share in this category. You need to compare how often each is named and how often each appears first, so both columns sit in one table. | Vendor | Named answers | Answer share | Named first answers | Named first share | | --- | --- | --- | --- | --- | | PostHog | 48/50 | 96% | 24/50 | 48% | | Amplitude | 50/50 | 100% | 15/50 | 30% | | Mixpanel | 50/50 | 100% | 11/50 | 22% | The two measures point in different directions. [Amplitude](https://www.memetik.ai/vendors/amplitude) and [Mixpanel](https://www.memetik.ai/vendors/mixpanel) lead on presence. [PostHog](https://www.memetik.ai/vendors/posthog) leads on position, at 48% of answers against 30% and 22%. ## Which tool was named first, and does the buyer's question change it? First-position counts differed across the five recorded question groups. PostHog led three groups overall. Amplitude led the comparison question, and Mixpanel led the B2B SaaS question. | Prompt | PostHog named first | Amplitude named first | Mixpanel named first | | --- | --- | --- | --- | | 1. What is the best product analytics tool for a startup? Name specific products. | 6/10 (60%) | 1/10 (10%) | 3/10 (30%) | | 2. Which product analytics tool would you recommend to a startup in 2026? | 9/10 (90%) | 1/10 (10%) | 0/10 (0%) | | 3. Compare the top product analytics tool options right now. | 1/10 (10%) | 9/10 (90%) | 0/10 (0%) | | 4. I'm a startup and I need a product analytics tool. What should I use and why? | 5/10 (50%) | 1/10 (10%) | 4/10 (40%) | | 5. Best product analytics tool for a B2B SaaS with 10k users? | 3/10 (30%) | 3/10 (30%) | 4/10 (40%) | In the recorded startup-recommendation answers, PostHog came first in nine of ten. In the comparison answers, Amplitude came first in nine of ten. Mixpanel never opened an answer to either of those two prompts, yet it led the B2B SaaS prompt. For the prompt about a B2B SaaS with 10k users, Mixpanel was named first in four answers. Amplitude and PostHog were each named first in three. All ten answers named Amplitude and Mixpanel; eight named PostHog. ## Do OpenAI, Anthropic, Google and Perplexity name the same tool first? No. The four provider families split, and the two smallest panels split hardest. | Provider family | Recorded answers | PostHog named first | Amplitude named first | Mixpanel named first | | --- | --- | --- | --- | --- | | OpenAI | 15 | 7/15 (46.7%) | 6/15 (40%) | 2/15 (13.3%) | | Anthropic | 15 | 6/15 (40%) | 4/15 (26.7%) | 5/15 (33.3%) | | Google | 10 | 9/10 (90%) | 1/10 (10%) | 0/10 (0%) | | Perplexity | 10 | 2/10 (20%) | 4/10 (40%) | 4/10 (40%) | Google's sampled models named PostHog first in nine of ten answers and Mixpanel first in none. Perplexity's sampled models put PostHog first in two of ten, with Amplitude and Mixpanel on four each. OpenAI and Anthropic sit closer together, with PostHog first in 7/15 and 6/15 respectively. The overall panel weights each sampled model equally. OpenAI and Anthropic each contribute 15 answers; Google and Perplexity each contribute ten answers in this category. ## How was the September 2026 product analytics sample collected? The September 2026 product analytics category contains 50 recorded answers from ten models across five fixed English-language buyer prompts. We report the dated sample and the exact questions so you can judge whether a visibility comparison supports your conclusion. Every raw answer is linked from the figures. Prompts stay fixed between editions. Four limits shape what the counts can carry. Alias matching is string-based. API models differ from consumer chat products. Prompts are English and not localised. ChatGPT via API returns few citations, so source counts under-represent it. Our full [method](https://www.memetik.ai/method) sets out the collection and matching rules. ## What can this visibility comparison not decide for you? It cannot decide which tool to buy. First position records where a product name appears in the text. Product quality, purchase suitability and recommendation strength are separate questions. One prompt-model response was collected for each combination in this edition. The results are a descriptive snapshot. Repeated, controlled trials would be needed to estimate repeatability or isolate effects of wording. A difference of one or two answers describes this sample. The run does not establish whether that difference would persist or disappear in another run. You want to inspect the different results across the five buyer questions and the limits of that one dated sample, which is why every figure links back to the raw answers.
