Best LLM Visibility Monitoring Tools

What Is LLM Visibility Monitoring?

LLM visibility monitoring is the practice of tracking how large language models — the AI systems behind ChatGPT, Perplexity, Gemini, and Copilot — reference, cite, and discuss your brand. Unlike traditional rank tracking (where you monitor SERP positions), LLM visibility monitoring tracks whether AI systems include your brand in their generated answers.

This matters because AI-generated answers are increasingly the first — and sometimes only — response users see. If ChatGPT recommends your competitor when asked "Who is the best [your category] in [your market]?" — and does not mention you — that is a visibility problem no traditional SEO tool will detect. For context on why this matters, see our guide on Generative Engine Optimization.

Top LLM Visibility Tools (2026)

Otterly.ai

Otterly is the most widely adopted LLM visibility platform. It runs automated prompt tests across ChatGPT, Perplexity, Gemini, and Google AI Overviews, tracking your brand's citation frequency over time. Standout features include historical trend tracking, sentiment analysis, and competitive benchmarking. The dashboard is clean and well-suited for monthly client reporting. From $150/month.

Profound

Profound targets agencies and enterprise teams that need deep competitive intelligence. It runs extensive prompt batteries (hundreds to thousands of queries per month) across multiple AI platforms. Its competitive analysis is the deepest in the category — showing not just whether you appear, but exactly how your mention frequency compares to every competitor. Enterprise pricing on request.

Peec AI

Peec stands out for pairing monitoring with actionable optimization recommendations. Beyond showing where you appear and where you do not, it suggests specific content changes to improve your LLM citation rates. Good for teams that want guidance, not just data. Mid-market pricing.

Knowatoa

A newer entrant focused specifically on brand perception in AI systems. Knowatoa tracks not just citations but the qualitative aspects of how AI describes your brand — sentiment, accuracy, and positioning relative to competitors. Particularly useful for brand teams concerned about how AI shapes public perception. Early-stage pricing.

HubSpot AI Search Grader (Free)

HubSpot's free AI Search Grader provides a basic AI visibility score by testing your brand across major AI platforms. It is limited in depth and query coverage, but it is free and provides a useful starting point for businesses that have never measured their AI visibility. Best used as an initial assessment before investing in a paid tool.

DIY LLM Visibility Monitoring

If you are not ready to invest in a paid tool, you can build a basic monitoring practice manually:

1. 1.Define 20-30 target queries that your ideal customers ask AI search engines. Mix branded, unbranded, and competitive queries.
2. 2.Test weekly across platforms: Ask each query in ChatGPT, Perplexity, and Gemini. Screenshot the results.
3. 3.Track in a spreadsheet: Record whether you were cited, the sentiment, which competitors appeared, and the date.
4. 4.Monitor referral traffic: Set up UTM tracking or check your analytics for traffic from perplexity.ai, chatgpt.com, and bing.com/chat.
5. 5.Review monthly: Look for trends — are you appearing more or less frequently? Are competitors gaining ground?

Manual monitoring is time-intensive but provides genuine insight. It is also the best way to understand what AI platforms are actually saying about your brand before investing in tooling.
