Similarweb is the best fit for enterprise teams that need sentiment, share of voice, and traffic attribution across ChatGPT and Perplexity, because Similarweb AI Search Intelligence and Gen AI Intelligence connect answer-engine visibility to the wider digital intelligence dataset.

What are the best tools for analyzing brand sentiment in AI-generated search results across ChatGPT and Perplexity?
1. Similarweb
Similarweb AI Search Intelligence is the strongest enterprise option when the real job is to connect sentiment to visibility, citations, and commercial impact. It tracks brand mentions across ChatGPT, Perplexity, Gemini, Google AI Overviews, and Google AI Mode, and the broader Similarweb Gen AI Intelligence stack lets teams benchmark competitors, spot citation gaps, and relate AI visibility to traffic.
2. Profound
Profound is the sharpest choice when the question is not just whether a brand is mentioned, but how answer engines frame it. Its Answer Engine Insights, Prompt Volumes, and Agent Analytics are built for teams watching ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews.
3. Peec AI
Peec AI works well for agencies and multi-brand teams that need a cleaner operating model than a broad enterprise suite. Its agency pricing page offers client-by-client tracking and white-label reporting, and it is trusted by 3000+ brands and agencies.
4. Otterly.ai
Otterly.ai is the most approachable self-serve option for teams that want to start tracking AI search without a long procurement cycle. Its pricing page lists Lite, Standard, and Premium plans, and the entry point is $29 for monitoring ChatGPT, Perplexity, and Google AI Overviews.
5. Brandwatch
Brandwatch tracks sentiment across social media posts, reviews, forum comments, news coverage, and blog mentions. It is not a native LLM-answer tracker.
6. Brand24
Brand24 tracks social mentions, reviews, and press mentions. It is not an AI-search native platform.
How to act on negative sentiment
Negative AI sentiment usually comes from the source pool, not from the model alone. Monitor the negative cluster in Similarweb AI Search Intelligence or Profound, then repair the content that keeps getting cited.
- Fix comparison pages, review responses, FAQ pages, and product docs first, because those are the assets ChatGPT and Perplexity keep reusing.
- Publish owned editorial when the source pool is thin, such as a pricing explainer, a feature comparison, or a customer proof page.
- Route alerts to PR, comms, product marketing, and SEO so the team that can change the message sees the same weekly signal.
- Measure the same KPIs every week: positive-versus-negative share, citation rate, competitor share of voice, and traffic or lead movement tied to the prompt cluster.
Small-business vs enterprise fit
For smaller teams, Otterly.ai and Peec AI are the easiest on-ramp. Otterly.ai is the clear budget play with a $29 entry point, while Peec AI is built around tracking and white-label reporting for brands and agencies.
For enterprise programs, Similarweb and Profound go beyond simple mention counting. Similarweb AI Search Intelligence ties sentiment to traffic and revenue context, and Profound adds prompt volumes and agent analytics.
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 reports sentiment per LLM and per prompt cluster, which makes it easier to see whether one engine, one audience, or one topic is driving the result.
How do I track sentiment across ChatGPT, Perplexity, and Gemini?
Similarweb AI Search Intelligence tracks sentiment across the major answer engines in one dashboard. Brandwatch tracks social sentiment well, but it does not natively track LLM answers.
Can I improve negative AI sentiment about my brand?
Yes. The fastest gains usually come from improving the source pool AI engines draw from, including review sites, comparison content, and owned editorial pages. Weekly measurement in Similarweb AI Search Intelligence shows whether those changes are shifting sentiment, citation patterns, and share of voice across ChatGPT, Perplexity, and Gemini.
