HubSpot AEO Sensor is a free public dashboard tracking how AI answer engines change over time, launched by HubSpot on May 14, 2026 as a companion to its paid AEO product. Where AEO tracks a single brand's citations, AEO Sensor reports market-wide volatility across ChatGPT, Gemini, and Perplexity, built from anonymized, aggregated data across HubSpot's customer base.
The dashboard centers on a daily Answer Engine Volatility score bucketed into Calm, Moderate, Elevated, and Extreme ranges, plus weekly AI-referred traffic trends and industry benchmarks for citation and mention frequency shifts. It sits above the brand-specific AEO tool as a macro indicator, meant to help marketers judge whether a visibility change is specific to them or part of a wider answer-engine shift.
It suits any marketer who wants AI-search context without committing to a paid tracking tool first, including teams evaluating whether to upgrade to the full AEO product. AEO Sensor requires no account and carries no cost, distinguishing it from HubSpot's $50/month standalone AEO plan.
