What are the best AI search monitoring platforms?

If by AI search monitoring you mean tracking how your brand appears in ChatGPT, Google AI Overviews/AI Mode, Perplexity, Gemini, Claude, Copilot, etc. — often called AI visibility, GEO, or AEO monitoring — the main platforms worth evaluating in 2026 are these. TechnologyAdvice+1

Platform	Particularly useful for	What it monitors/does
Profound	Enterprise teams	AI visibility, citations, prompt volumes, competitors, sentiment, agent analytics
Peec AI	Marketing/SEO teams	Visibility, citations, source-gap analysis, competitors, multi-country tracking
Otterly.AI	SMBs & agencies	Affordable prompt tracking across major AI engines, mentions, citations, sentiment
Scrunch AI	Enterprise GEO + technical teams	AI visibility, citations, crawler/agent activity, hallucination detection, optimization
AthenaHQ	Enterprise brand governance	Cross-platform monitoring, competitor tracking, hallucination detection
Ahrefs Brand Radar	Existing Ahrefs users	AI mentions/citations + competitive benchmarking alongside traditional SEO
Semrush AI Visibility Toolkit	Existing Semrush users	AI visibility combined with the broader SEO/content ecosystem
Promptwatch	Teams wanting monitoring + action	AI visibility, content agents, crawler logs and broader GEO workflows

These aren't really interchangeable: some are pure monitoring products, while others increasingly try to turn monitoring into an optimization workflow. Data for AI Search+1

The shortlist I'd investigate

1. Profound — enterprise / deep intelligence Strong if you need sophisticated enterprise measurement, particularly prompt-demand data, citations and competitive intelligence. Its pricing and packaging have changed considerably in 2026, so I'd verify the current commercial offering before budgeting. Data for AI Search

2. Peec AI — analytics-focused monitoring Interesting if you care about understanding why competitors appear in AI answers: citations, sources, visibility and competitive gaps. It is also particularly relevant for European teams; current comparisons highlight its EU/GDPR-oriented positioning. SEO Compare+1

3. Otterly.AI — inexpensive way to get started A relatively low-friction option for tracking prompts and AI visibility without buying an enterprise platform. Current published comparisons put entry pricing around $29/month, although engine coverage and prompt limits vary by plan. Best GEO Software+1

4. Scrunch AI — monitoring + technical AI visibility More differentiated if you want to go beyond simply measuring mentions and investigate AI crawlers, citations and how content is presented to AI systems. TechnologyAdvice+1

5. Ahrefs / Semrush — if you're already paying for SEO If your team already lives in Ahrefs or Semrush, their AI-visibility capabilities can make more sense than adding another standalone dashboard. They combine AI visibility with conventional SEO data. TechnologyAdvice+1

One important buying criterion

Don't choose purely on number of AI engines tracked. The more useful questions are:

• Can I track the exact prompts my customers use?
• Does it distinguish brand mentions from actual citations/links?
• Can I see which sources AI systems rely on?
• Can I benchmark against competitors?
• Does it support country/language-specific prompts?
• Can I export the underlying data/API?
• Does it tell me what to change, or merely report the problem?
• How much do additional models, prompts and seats cost?

The market is changing quickly, and published comparisons are already showing substantial differences between headline pricing and the cost of getting the engine/prompt coverage a real team needs. Data for AI Search+1

If you tell me whether you're a startup, SEO agency, enterprise marketing team, or SaaS company, I can narrow this to 3–4 platforms and compare their current pricing, AI engines, prompt limits, API/reporting, and key weaknesses.
