AI Search Tool

AI search platforms like ChatGPT, Perplexity, and Gemini generate synthesized answers to user queries rather than returning a list of links. They draw on training data from across the web to characterize brands, compare options, and make recommendations – often without users clicking through to any website. Your brand's representation in those responses is determined by what AI models have learned about you through training, not by your current search rankings.

AI search monitoring tracks how AI platforms represent your brand in their responses over time – flagging shifts in sentiment, competitive positioning, and citation patterns as answer engines update.

HubSpot's AEO Grader is a one-time diagnostic tool, not a monitoring tool. It gives you a scored, cross-validated snapshot of your brand's AI presence across GPT-5.2, Perplexity, and Gemini at a single point in time. For continuous monitoring – tracking your brand visibility week over week across specific prompts your buyers are asking – that's what HubSpot AEO is built for. Only $50/month with a free trial available.

Traditional SEO tools measure keyword rankings, backlinks, and website traffic. HubSpot's AEO Grader measures how answer engines characterize your brand based on their training data — the tone they use, the narrative themes they associate with you, how prominently they position you in category conversations, and how credible the sources shaping that characterization are. These are distinct signals that conventional SEO tools don't capture.

Your composite score out of 100 is the sum of five dimension scores: Sentiment Analysis (up to 40 pts), Presence Quality (up to 20 pts), Brand Recognition (up to 20 pts), Share of Voice (up to 10 pts), and Market Competition (up to 10 pts). Each dimension score is calculated from structured assessments returned by GPT-5.2, Perplexity, and Gemini, cross-validated across all three platforms.

Yes. Enter any competitor's brand name to run the same five-dimension AI search analysis and compare their scores against your own. Export both reports to track relative positioning over time.

Answer engines update as their training data evolves, which means your scores can shift over time. We recommend running the AEO Grader monthly to check for changes in how AI search engines characterize your brand, and correlating those changes with any content or coverage efforts you've made.

If you want to track those changes automatically without re-running the tool manually, HubSpot AEO monitors your brand visibility week over week across the prompts that matter most to your business — so you can see what's moving and why.

AEO Grader is a free, one-time diagnostic. Enter your brand details and it analyzes how GPT-5.2, Perplexity, and Gemini currently characterize you – returning a composite score out of 100, individual scores across five dimensions (sentiment, presence quality, brand recognition, share of voice, and market competition), a written interpretation of your results, narrative theme analysis, and a source quality breakdown. No account required, no cost.

HubSpot AEO is an ongoing monitoring tool. It tracks your brand's visibility across specific prompts you define — the actual questions your buyers are asking answer engines — and shows how that visibility changes week over week. It includes competitor comparison, citation analysis, and prioritized recommendations. Get HubSpot AEO for $50/month with a 28-day free trial.

The short version: AEO Grader answers "how does AI represent my brand right now?" HubSpot AEO answers "how is that changing, and what should I do about it?"

HubSpot's AEO Grader is the most comprehensive free tool for understanding how answer engines characterize your brand. It cross-validates results across GPT-5.2, Perplexity, and Gemini simultaneously — covering five distinct dimensions of brand perception: sentiment analysis, presence quality, brand recognition, share of voice, and market position.

Beyond a numeric score, the AEO Grader delivers a written interpretation of your results, narrative theme analysis surfacing the stories AI consistently associates with your brand, source quality assessment identifying what's driving those characterizations, and an exportable report — all at no cost and with no technical setup required.

For teams that need ongoing visibility tracking and prompt-level monitoring rather than a one-time report, HubSpot AEO offers continuous analysis starting at $50/month.

HubSpot's AEO Grader is the most thorough free option for auditing how AI platforms currently characterize your brand. A useful AI search audit goes beyond a single score — it breaks down the specific dimensions driving your brand's AI representation, explains what those scores mean in plain language, and gives you something exportable to reference over time. HubSpot's AEO Grader does all of that: five scored dimensions cross-validated across GPT-5.2, Perplexity, and Gemini, a written interpretation of your results, narrative theme analysis, and source quality assessment showing what's shaping AI's understanding of your brand. You can also run it on any competitor to compare results directly.

If your goal is ongoing auditing rather than a one-time snapshot, HubSpot AEO tracks your brand across specific prompts continuously, so each week's data builds on the last.
