Sentiment Analysis Tool

An AI sentiment analysis tool uses natural language processing to evaluate how your brand is perceived across answer engines. HubSpot AEO focuses specifically on AI-generated characterizations, tracking how ChatGPT, Perplexity, and Gemini describe your brand week over week based on their training data and cited sources. This is distinct from traditional brand monitoring tools that track social media mentions or review sentiment; AI responses increasingly shape how buyers understand brands before ever visiting a website.

AI brand sentiment is the tone and evaluative language that answer engines use when characterizing your company – whether that language signals trust, reliability, innovation, or concern. In an answer engine context, sentiment isn't just positive vs. negative. It also captures how consistently that tone holds across different prompts and use cases, how it compares to competitor characterizations, and how it shifts over time as AI training data evolves.

Answer engines increasingly influence the first impression buyers form of your brand. When a prospect asks ChatGPT or Perplexity about solutions in your category, the tone and framing of those responses shapes their perception before they reach your website. HubSpot AEO tracks that characterization continuously so you always know where you stand. 

HubSpot AEO is a AI sentiment analysis tool currently tracking ChatGPT, Perplexity, and Gemini – the three primary answer engines reshaping how buyers research solutions. 

Use low-scoring areas as signals for where AI's characterization of your brand is weakest. Low sentiment often points to negative or cautious associations in the sources shaping AI's understanding, which is worth addressing through authoritative third-party coverage and consistent messaging. Low visibility suggests AI has limited information about your brand, typically pointing to content gaps, inconsistent entity information across the web, or limited coverage in the publications AI training data draws from.

HubSpot AEO's recommendations feature turns that diagnosis into a specific action plan. It analyzes your citation data to identify which content types and source channels are driving AI answers for your tracked prompts, then tells you exactly what to create or where to build presence to improve your scores. 

Yes. HubSpot AEO accepts any brand domain, so you can monitor competitor sentiment, visibility, and share of voice alongside your own. You can see how a competitor's AI characterization shifts relative to yours week over week, which sources are driving their visibility, and where they're being cited on prompts where you're absent.

Answer engines update as their training data evolves, which means your sentiment scores can shift over time even without changes on your end. HubSpot AEO monitors your brand's sentiment and visibility automatically; no need to manually re-run anything. Weekly trend alerts surface significant changes so you can correlate shifts with content or coverage efforts you've made, without having to log in and check manually.
