Feature · AI Sentiment Analysis

Not just positive or negative. Is AI building the right narrative?

AI models rarely speak badly about brands, that makes standard sentiment scores meaningless. Prominence benchmarks your tone against the category average to tell you when you're truly overperforming, holding neutral ground, or falling behind your peers.

The Sentiment Challenge

LLMs don't speak badly about brands. That makes standard sentiment almost useless.

Traditional sentiment tools ask a binary question: is the tone around your brand positive, neutral, or negative? In web search, that distinction is meaningful. In AI-generated answers, almost everything sits in positive or neutral territory. The model is designed to be helpful, not to pass judgement.

A real problem only shows up in comparison. If the entire category averages 62 and your brand scores 46, that gap is the signal. An absolute score of 46 looks fine on paper; relative to your category, it is a red flag.

Prominence builds a dynamic category baseline from the same responses we collect for your competitive set. Every response is scored semantically and compared to that baseline, placing it in one of three tiers: Overperforming, Neutral, or Underperforming.

The result is a sentiment signal that actually moves, trends you can track week over week, and a benchmark that tells you whether your brand is capturing the narrative or ceding it.

How It Works

From AI response to sentiment signal

01

Connect your brand and category

Set up your brand, the competitors you want to benchmark against, and the prompt set that covers your category. This configuration drives both your visibility metrics and your sentiment analysis without any additional setup.

02

AI responses collected at scale

Prominence continuously collects AI-generated answers across ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity, and Copilot. Every response mentioning your brand or category is captured for semantic analysis.

03

Semantic sentiment scoring

Each response is scored semantically, not by keyword matching, but by evaluating the meaning and tone of the language the model uses. Scores reflect the warmth or caution of the description in context, not just the presence of positive or negative words.

04

Category baseline and tier assignment

Your brand score is compared against the dynamic category average drawn from your competitive set. Responses that sit significantly above average are classified as Overperforming. Those within the typical range are Neutral. Those below are Underperforming.

05

Trends, model breakdown, and segment drill-down

Weekly trend charts show how your sentiment tier mix evolves over time. Segment views let you isolate performance by product dimension or use case. Model comparisons reveal where specific AI platforms treat your brand differently from the rest.

Personal Insight

“A sentiment score in isolation is a vanity metric.
The signal is whether you beat the category, not whether AI was polite.”

AI models are recommendation engines, and recommendation engines are built to be agreeable. They rarely speak badly about a brand, so almost everyone scores "positive". That is exactly why a raw sentiment number tells you nothing about where you actually stand.

The brand teams we work with had all hit the same wall: their dashboards were green, yet they could feel the narrative slipping. The flaw was never the data, it was the absence of a reference point. Positive against what? Liked more than whom?

Sentiment here is measured against the category, not the brand alone. We compute a live average across your competitive set and measure you against it, so every response lands as overperforming, neutral, or underperforming. Suddenly the metric moves, and when it moves it means something.

From there it gets actionable: track the tier mix week over week, break it down by model, and drill into the segments that define your market. That is how a soft qualitative signal becomes a number a brand team can actually steer.

Frequently Asked Questions

Everything you need to know about AI Sentiment Analysis and brand perception measurement.

The Method

AI Sentiment Analysis is a module inside Prominence AI's Brand Perception suite. It measures the tone AI models project around your brand when they generate answers about your category. Rather than a simple positive-neutral-negative score, it benchmarks your sentiment against the category average so you can see when you are overperforming, holding neutral ground, or falling behind, and how that changes week over week.
Large language models are trained to be helpful and generally avoid overtly negative language about brands. A scale that flags only explicit negativity misses most of the signal. The strategic question is not whether the tone is negative in absolute terms, but whether your brand is receiving a warmer response than your category peers. By measuring against a category baseline, we surface meaningful differences even when the absolute language is consistently mild.
Each AI response is scored semantically and then compared against the average score for your category. Responses that are meaningfully more positive than the category baseline are classified as Overperforming. Those that sit within the typical range are Neutral. Those that fall below it are Underperforming. This three-tier system gives your team a clear, actionable signal rather than a number that is hard to interpret in isolation.
Sentiment analysis runs on the AI responses already collected for your brand and category across the models you track in Prominence AI: ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity, and Copilot. No additional prompting is needed. The same corpus that drives your visibility metrics also feeds the sentiment layer.

Metrics & Segments

The Sentiment Score is a 0-to-100 index that summarises how positively AI models describe your brand across the responses collected in the selected period. It combines the semantic tone of each response and weights it against the category baseline. A score of 46.8 does not mean 46.8 percent positive, it reflects your relative position on the scale calibrated to your category.
Yes. You can filter and compare sentiment by AI model (for example, see whether Perplexity is more cautious about your brand than ChatGPT), by market (global vs a specific country), and by the prompt segments you have configured for your account. This lets you identify whether a sentiment challenge is universal or tied to a specific model or audience context.
Segments are the sub-topics you monitor within your category, such as olfactory notes, longevity, or user recommendation in a fragrance category. Segment Performance Analysis shows your sentiment score and trend for each segment individually. This tells you not just how your brand is perceived overall, but which product dimensions or use cases are driving the strongest or weakest sentiment in AI answers.
Sentiment data updates in line with your response collection schedule. Trend charts reflect weekly aggregates so you can track narrative shifts over time without noise from day-to-day variation. The weekly cadence is the right resolution for detecting genuine perception shifts rather than short-term fluctuations.

Acting on Results

An Underperforming result tells you where the gap is, not what caused it. To understand which content and sources are shaping that narrative, pair AI Sentiment Analysis with Grounding Source Prominence: GSP reveals which domains and pages AI models draw on when describing your brand. Together, the two modules give you the diagnostic and the source map you need to build a content strategy that shifts the needle.
AI Sentiment Analysis and Brand Voice Alignment answer different questions. Sentiment tells you whether the overall tone is above, at, or below category average. Brand Voice Alignment tells you whether the specific attributes you care about, luxury, innovation, sustainability, are being projected the way you intend. Use sentiment for the pulse check, and Brand Voice Alignment for the positioning audit.
Yes. The competitor benchmark shows the sentiment distribution and score for the brands you track, so you can see whether your Neutral rating reflects a category-wide pattern or whether specific competitors are consistently overperforming you. Changes in competitor sentiment can also signal shifts in how the category is being described that may affect your brand indirectly.
