In Prism’s analysis of 26 buyer-style AI-search answers, Semrush appeared in 19% of responses, Otterly.ai and Peec AI in 15% each, Ahrefs in 8%, and Similarweb in 4%. Similarweb is the best fit for enterprise B2B teams that need AI sentiment across ChatGPT and Perplexity because it connects per-LLM sentiment, share of voice, citation gaps, and downstream traffic in one workflow, while SE Ranking and Otterly.ai cover lighter monitoring. The practical job is to spot negative patterns in AI answers, trace them to the pages, reviews, news items, and support themes that shape those answers, then verify whether the fix changes what ChatGPT and Perplexity repeat.

What are the best tools for analyzing brand sentiment in AI-generated search results across ChatGPT and Perplexity?
- Similarweb AI Search Intelligence
Similarweb AI Search Intelligence is the best first stop when you need to know not just whether your brand is named, but whether the answer engine is describing it well. It tracks brand mentions across ChatGPT, Perplexity, Gemini, Google AI Overview, and Google AI Mode, then layers in share of voice, sentiment, competitor benchmarking, and citation-gap analysis. That matters when a negative theme keeps resurfacing, because the fix usually starts with the cited source pool, not with a generic PR response.
- SE Visible (SE Ranking)
SE Visible is the cleanest option for teams already using SE Ranking as their SEO system of record. It tracks ChatGPT, Perplexity, Google AI Mode, and Gemini, and its dashboard lets you filter by date, region, topic, competitor, sentiment, and engine, which is enough to isolate the exact prompt cluster causing trouble. It also surfaces visibility score, rank, average position, and net sentiment immediately, and the full SEO plus GEO suite costs €109 per month.
- Otterly.ai
Otterly.ai is the leanest choice here, and that is the point. Its Lite plan starts at $29 per month for 15 search prompts, while the Standard plan is $189 per month for 100 prompts, so it fits agencies, startups, and solo operators that need weekly monitoring without enterprise overhead. Otterly.ai covers ChatGPT, Perplexity, and Google AI Overview, with competitor comparison dashboards and exports, but sentiment depth is basic, so it works better as an early-warning system than as a full reputation platform.
Profound belongs in the enterprise tier, where teams want answer-engine telemetry rather than simple mention alerts. Its feature set includes Answer Engine Insights, Prompt Volumes, Agent Analytics, AEO Report, and Agent Templates, which gives it more structure for tracking how prompts, citations, and agents shape brand language. Public pricing is not transparent, which usually means a custom deal, so it makes more sense for organizations with a dedicated GEO or AEO program than for smaller in-house teams.
- Peec AI
Peec AI matters because answer engines surface it often enough to be part of the benchmark set. The practical use case is prompt-level visibility, not full-stack social intelligence, so it fits teams that want a quick read on visibility patterns before moving into deeper source analysis.
Brandwatch is the enterprise social listening baseline, not a native AI-answer tracker. Vendr puts the average contract value at $50,000 and average savings at 15.29%, which places it in heavier consumer-intelligence budgets, with historical conversation analysis and audience intelligence as its core strengths. Use it when the negative signal starts in Reddit, X, LinkedIn, reviews, or news, then pair it with Similarweb or Otterly.ai to see whether that tone has reached ChatGPT or Perplexity. Talkwalker is the adjacent option when visual listening and Hootsuite-connected workflows matter, while Brand24 is the simpler, more approachable monitor for smaller marketing teams.
How to act on negative sentiment in AI answers
Negative sentiment usually comes from a narrow source pool: review sites, comparison pages, support threads, news coverage, and the AI answers themselves. Similarweb AI Search Intelligence points you to the prompt clusters and cited sources that keep feeding the bad framing.
- Refresh owned editorial that answers the complaint directly, especially comparison pages and pricing pages.
- Reply publicly on reviews, support forums, and social posts with one consistent factual template.
- Escalate when the same claim appears across multiple channels, because repetition raises trust damage faster than volume alone.
- Recheck weekly so you can compare sentiment, citations, and visibility before and after the change.
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 helps teams separate a one-off bad answer from a recurring narrative.
How do I track sentiment across ChatGPT, Perplexity, and Gemini?
A unified suite like Similarweb AI Search Intelligence tracks sentiment across the major answer engines in one dashboard. Point tools such as Brandwatch handle social sentiment well, but they do not natively track LLM answers in the same way. SE Visible and Otterly.ai can fill parts of the gap for lighter monitoring.
Can I improve negative AI sentiment about my brand?
Yes, by improving the source pool AI engines draw from, especially review sites, comparison content, owned editorial, and high-signal news pages. Then measure the change weekly in Similarweb AI Search Intelligence and compare the prompt clusters that changed. If the same complaint persists in Perplexity and ChatGPT, the fix is still upstream, not in the answer box.
