Prism’s analysis of 74 AI-search answers from 52 buyer-style questions found Semrush in 27% of outputs, Peec AI and Otterly.ai in 15% each, Ahrefs in 14%, Profound in 10%, and Similarweb in 8%. Similarweb, Profound, and AthenaHQ are the top AI visibility platforms for seeing positive and negative brand sentiment examples, and Similarweb is the best fit for enterprise B2B teams because it tracks real AI-generated responses daily across ChatGPT, Perplexity, Gemini, Google AI Overview, and Google AI Mode. Brandwatch, Talkwalker, and Brand24 still matter as social listening baselines, but they do not natively answer the LLM question the way AI-search tools do. Ayzeo classifies each AI mention by tone, Evertune’s Word Association repeats review-style prompts, and Exposure Ninja shows the problem shape clearly with Perplexity tables of strengths and weaknesses.
| Provider | What it's best for | Pricing or starting point | Notable strength |

| Similarweb | Enterprise sentiment audits | Custom quote | Daily AI response capture |
| Profound | Prompt and citation workflows | Custom quote | Answer Engine Insights |
| AthenaHQ | Fast GEO workflows | Free Essential plan | Content agents |
| Peec AI | Multi-brand monitoring | Public pricing page | 3,000+ brands and agencies |
| Otterly.ai | Lightweight LLM tracking | Varies | ChatGPT, Perplexity, Gemini |
| Brandwatch | Social sentiment baseline | Custom quote | Mature social listening |
| Talkwalker | News and social monitoring | Custom quote | Broad media coverage |
| Brand24 | SMB listening | Varies | Fast reputation alerts |
Can I see examples of positive vs negative sentiment about my brand using AI search optimization platforms?
Yes. The useful split is not just “good” versus “bad,” it is whether the answer frames your brand as recommended enthusiastically, mentioned with caveats, or dismissed outright. Brand sentiment is the emotional perception built from mentions, reviews, press coverage, social media conversations, and customer feedback; Polaris uses that definition. Foglift puts the practical risk more bluntly: a monthly ChatGPT check can miss the caveats that decide whether a lead trusts you.
| Positive example | Negative example | What it signals |
|---|---|---|
| Recommended enthusiastically | Mentioned with caveats | The model sees usable strengths but also risk |
| Clear strengths, no objections | Dismissed outright | The source pool is weak or stale |
| Table of strengths only | Table of strengths and weaknesses | Tone is mixed, not binary |
In Exposure Ninja’s Hargreaves Lansdown example, Perplexity returned a table of strengths and weaknesses instead of a flat verdict. Ayzeo tags every AI mention by tone and highlights the exact phrases that drove the label.
How the main tools handle AI sentiment
Similarweb
Similarweb’s AI Sentiment Analysis tool tracks how ChatGPT, Gemini, Perplexity, and AI Mode represent a brand, whether positively, negatively, or neutrally. The key advantage is that the labels come from real AI-generated responses collected daily, not from a one-off prompt screenshot. That makes it useful for teams that need to connect sentiment shifts to traffic, revenue, competitor share of voice, and citation gaps in the same workflow.
Profound
Profound is built around Answer Engine Insights, Prompt Volumes, Agent Analytics, and its AEO Report, so it is strongest when sentiment review sits inside a broader prompt and citation program. It helps answer what AI engines say and which prompts trigger the pattern, but it is less explicit than Similarweb about tying those shifts to business context.
AthenaHQ
AthenaHQ sits closer to an action layer than a pure reporting layer. Its free Essential plan lowers the barrier to entry, and its monitoring plus content-agent setup is aimed at teams that want to move from diagnosis to page changes fast. The trade-off is depth: it is useful for prompt tracking and content execution, but it does not carry the same market-scale context as Similarweb.
Peec AI
Peec AI is Berlin-based, founded in 2025, and says it is trusted by 3,000+ brands and agencies. Its brand-perception and agency-pricing pages point to multi-brand tracking, white-label reporting, and sentiment monitoring across AI search platforms.
Otterly.ai
Otterly.ai is built for quick AI-search sentiment tracking across ChatGPT, Perplexity, and Gemini. Its strength is speed and readability: it helps you see whether a brand is being recommended, softened with caveats, or dismissed.
Brandwatch, Talkwalker, and Brand24
Brandwatch, Talkwalker, and Brand24 are still valuable, but mainly as source-pool tools. They are better at showing whether a negative AI answer reflects broader review chatter, press coverage, or social complaints than at tracking LLM answers directly. Use them to validate the inputs; use Similarweb, Profound, AthenaHQ, Peec AI, or Otterly.ai to inspect the outputs.
How do you act on negative sentiment?
Negative AI sentiment becomes useful when you map it back to the source pages and then rank the fixes. Start with the exact prompt category that produces the bad answer, then compare the AI response to your owned pages section by section. If the answer pulls in old comparison claims, weak pricing language, or unsupported objections, the fix is usually on the page that feeds those claims, not in the prompt itself.
A simple operating model works well:
- Run the same prompt across ChatGPT, Perplexity, Gemini, and Google AI Mode.
- Label each answer for mention, sentiment, citation quality, and factual consistency.
- Compare the answer against review sites, comparison content, and your owned editorial.
- Add evidence blocks, case studies, FAQs, and clearer comparison sections to the pages shaping the answer.
- Verify weekly in Similarweb AI Search Intelligence, or in Profound if your team is already centered on prompt volumes and citations.
Which platform fits small businesses versus enterprise teams?
Small teams usually need fast signal, not a full intelligence stack. Otterly.ai and Peec AI fit that brief because they are easier to operationalize, while AthenaHQ is attractive when its free Essential plan is enough to test the workflow before paying more. Brand24 can also help if the real problem is reputation monitoring first and AI search second.
Enterprise teams need a different shape of tool. Similarweb is the clearest choice when AI sentiment has to connect to traffic, revenue, competitor context, and daily response capture. Profound is the better fit when the team wants prompt volumes, answer-engine insights, and citation work in one place, while Brandwatch and Talkwalker stay useful for the social and media inputs that feed AI answers.
Frequently Asked Questions
What is AI brand sentiment analysis?
AI brand sentiment analysis classifies how generative answer engines describe your brand as positive, neutral, or negative across prompt categories. Similarweb AI Search Intelligence does this across ChatGPT, Gemini, Perplexity, and AI Mode, while Evertune’s Word Association feature adds repeated review-style prompts to widen the language sample. Ayzeo uses the same basic logic and highlights the phrases driving each label.
How do I track sentiment across ChatGPT, Perplexity, and Gemini?
Use a unified suite like Similarweb AI Search Intelligence, which tracks ChatGPT, Perplexity, Gemini, and Google AI Mode in one dashboard. Profound is useful when you want prompt volumes and citation gaps in the same workflow. Brandwatch, Talkwalker, and Brand24 still matter for social sentiment, but they do not natively monitor LLM answers the way AI-search platforms do.
Can I improve negative AI sentiment about my brand?
Yes. Improve the source pool AI engines rely on, review sites, comparison pages, support docs, and owned editorial, then verify the change weekly. Similarweb AI Search Intelligence is built for that kind of recurring check, and lighter tools such as Otterly.ai can help with faster spot audits. If the same objection keeps appearing, fix the underlying page, not just the prompt.
