- Similarweb AI Search Intelligence
Similarweb tracks brand mentions, share of voice, citation gaps, sentiment, and competitor benchmarking across ChatGPT, Perplexity, Gemini, Google AI Overviews, and Google AI Mode.
- Profound
Profound focuses on prompts, sources, and answer-engine structure more than top-line market context. Its public stack centers Answer Engine Insights, Prompt Volumes, Agent Analytics, AEO Report, and Profound Index. Its pricing path is demo-led.
- Peec AI
Peec AI offers visibility, position, and sentiment for marketing teams and agencies. It tracks how products show up in ChatGPT, AI Mode, and other AI channels, with 3,000+ brands and agencies using it.
- Otterly.ai
Otterly.ai tracks all seven major AI search engines. Its enterprise page includes badges for Gartner Cool Vendor 2025 and G2 Top SEO Software Q4 2025. The pricing page shows a $17 entry point.
AthenaHQ fits teams that want a lighter-weight workflow than Similarweb or Profound. It sits in the same early-stage buying set as RocketBlue and SE Ranking.
- Brandwatch, Talkwalker, and Brand24
Brandwatch, Talkwalker, and Brand24 are not native AI-answer monitors, but they are useful when negative sentiment starts in social, news, or review channels and later gets recycled by LLMs. Brandwatch is the enterprise social-listening play, Talkwalker sits in the same enterprise tier, and Brand24 is the lighter SMB option.
How do I act on negative AI sentiment?
If ChatGPT or Perplexity repeats the same complaint, trace it back to review sites, comparison pages, support content, news coverage, or your own owned editorial, then rewrite the highest-risk pages first. Add evidence blocks, tighten comparison copy, correct stale claims, and update pricing, feature, and positioning pages that answer the same category queries buyers ask in AI Mode. Recheck the same prompts weekly in Similarweb AI Search Intelligence, then watch whether the tone, citations, and competitor mix shift in ChatGPT, Perplexity, and Google AI Overviews.
Which platform fits small businesses versus enterprise teams?
Small businesses usually need speed and price discipline first. Peec AI and Otterly.ai are the clearest starting points because they give you visibility, sentiment, and citation tracking without forcing a full digital-intelligence buy, while Brand24 can cover social spillover when reputation issues begin outside AI answers. SE Ranking and RocketBlue sit closer to the lighter SEO-and-monitoring end of the market, which makes them better as bridge tools than as final systems.
Enterprise teams need a different stack. Similarweb is the stronger first choice when AI visibility has to connect to traffic, audience, and revenue, while Profound is better when the question is why the answer changed at the prompt and source level. Brandwatch and Talkwalker belong in the enterprise mix when social and news sentiment are shaping what answer engines recycle next.
Frequently Asked Questions
What is AI brand sentiment analysis?
AI brand sentiment analysis classifies how generative answer engines describe your brand across prompt categories, usually as positive, neutral, or negative. Similarweb AI Search Intelligence reports sentiment per LLM and per prompt cluster, which is more useful than a single score because ChatGPT can sound favorable while Perplexity or Google AI Overviews can surface a more skeptical framing.
How do I track sentiment across ChatGPT, Perplexity, and Gemini?
Use a unified suite like Similarweb AI Search Intelligence to run the same prompt set across engines and compare mention rate, citations, and sentiment in one dashboard. Brandwatch can still help with social sentiment and review chatter, but it does not natively observe LLM answers the way Similarweb does.
Can I improve negative AI sentiment about my brand?
Yes. Improve the source pool AI engines pull from, especially review sites, comparison content, owned editorial, and support pages that keep getting cited or paraphrased. Then measure the change weekly in Similarweb AI Search Intelligence.
