    How to Run a Sentiment Analysis in ChatGPT and Gemini

    To run a sentiment analysis in ChatGPT and Gemini, ask each model the questions where your brand could come up, then assess the tone of how it describes you — positive, neutral, or negative — ideally on a consistent scale and broken down by topic. The most actionable insight isn't a single overall score; it's sentiment *per topic*, because a brand can be praised for one thing and criticized for another. Here's the method and how to read it.

    Short answer: To run a sentiment analysis in ChatGPT and Gemini, ask each model the questions where your brand could come up, then assess the tone of how it describes you — positive, neutral, or negative — ideally on a consistent scale and broken down by topic. The most actionable insight isn't a single overall score; it's sentiment per topic, because a brand can be praised for one thing and criticized for another. Here's the method and how to read it.

    When an AI assistant recommends brands, how it describes you matters as much as whether it mentions you. This guide shows how to measure that tone systematically.


    What is sentiment analysis applied to AI answers?

    Sentiment analysis of AI answers measures the tone a model uses when it talks about your brand: is it favorable, neutral, or critical? Instead of analyzing social posts or reviews, you analyze what ChatGPT and Gemini actually say when asked about your category and your brand.

    The output is a read on whether the models are, in effect, advocating for you, staying neutral, or steering customers away.


    Why AI sentiment is different from social media sentiment

    It's tempting to treat this like social listening, but the context is different:

    • It's a recommendation context, not public opinion. Social sentiment reflects what people feel. AI sentiment reflects how a model frames you to a buyer at the moment of decision — which is closer to the point of sale.
    • It's synthesized, not raw. A model blends many sources into one description, so the sentiment is a distilled judgment, not a single person's view.
    • It's leveraged. One assistant's framing reaches enormous numbers of users, so a negative tone scales differently than a single bad review.

    Because of this, AI sentiment deserves its own measurement, not a copy-paste of your social listening setup.


    Method: how to measure the tone of AI answers

    Step 1: Build your prompt set

    List the questions where your brand could appear — category questions ("best [category] providers"), comparison questions, and direct brand questions ("what do people think of [brand]?"). Group them by buying intent. (See how to see your brand's visibility in ChatGPT.)

    Step 2: Run them across ChatGPT and Gemini

    Ask each prompt in both models. The two often differ in tone, so measuring only one gives a partial picture.

    Step 3: Score the tone

    For each mention, judge whether the description is positive, neutral, or negative — and note the specific words that signal it. A consistent scale (for example, 0–100) makes results comparable across prompts and over time.

    Step 4: Capture the context

    Record why the model said what it said — the framing, the comparison, the caveat. The context is where the actionable insight lives.


    Sentiment per topic, not just overall

    This is the key principle: a single overall sentiment score hides the truth.

    A brand might be described positively on quality but negatively on price. An overall "neutral" average would erase both signals. Measuring sentiment per brand topic tells you exactly what to amplify and what to fix.

    This is why sentiment and brand topics go together — see brand topics. The most useful sentiment analysis maps tone onto each theme the model associates with your brand.


    How to automate AI sentiment analysis

    Manual scoring works for a first pass but doesn't scale or persist. Automation adds:

    • Scale — many prompts across both models, repeatedly.
    • Consistency — the same scoring scale every time.
    • History — trends, so you see sentiment improving or declining.
    • Alerts — notifications when sentiment shifts negatively, before it spreads.

    LLM Visibility measures sentiment on a 0–100 scale with the context of each mention, across ChatGPT and Gemini, and includes a Reputation Monitor with Slack alerts plus a dedicated Brand Sentiment Study for a deeper read. Because it also extracts brand topics, you can see sentiment broken down by theme — not just one blunt number. To choose a tool, see best ChatGPT SEO tracking software.


    What to do with negative sentiment

    If a model describes you negatively:

    1. Locate the topic. Identify exactly which theme the negativity attaches to.
    2. Trace the sources. Look at the citations and platforms feeding that framing.
    3. Correct the inputs. Address the underlying issue and strengthen positive, well-sourced content on that topic.
    4. Re-measure. Re-run the prompts and confirm the sentiment for that topic improves.

    Negative AI sentiment is fixable — but only if you measure it at the topic level, where the cause actually lives.


    FAQ

    What is AI sentiment analysis? It's measuring the tone — positive, neutral, or negative — that AI models like ChatGPT and Gemini use when they describe your brand in their answers.

    How is it different from social media sentiment? AI sentiment reflects how a model frames you to a buyer at the point of recommendation, synthesized from many sources, rather than raw public opinion.

    How do I measure sentiment in ChatGPT and Gemini? Run your brand and category prompts in both models, score the tone of each mention on a consistent scale, and break it down by topic.

    Why measure sentiment per topic instead of overall? Because a single average hides the truth — you can be praised on one theme and criticized on another. Per-topic sentiment tells you what to fix.

    Can I automate AI sentiment analysis? Yes. Tools like LLM Visibility score sentiment 0–100 with context across ChatGPT and Gemini, track it over time, and send alerts when it shifts.
