Only 16% of brands systematically track AI search performance according to Erlin's 2026 LLM brand visibility analysis, even as AI engines now drive a growing share of buyer research and discovery. The best AI visibility tools track brand citations across ChatGPT, Perplexity, Gemini, AI Overviews, AI Mode, Claude, and Copilot (which is something we cover in our primer on AEO), surfacing where competitors are getting cited instead of you and what content changes would close the gap. We've tested most of the platforms below across client deployments at RZLT and shortlisted the ones that have actually earned their place in production stacks.

Profound: Enterprise AI visibility with consumer panel data and conversion analytics

Profound is the enterprise AI visibility platform with the largest behavioral data footprint, analyzing 30 billion AI crawler visits and over a billion citations daily across ChatGPT, Gemini, Perplexity, Claude, and beyond. The platform connects AI visibility data to actual conversion behavior through real consumer panel data rather than synthetic API estimates, and includes dedicated ChatGPT Shopping tracking for e-commerce brands. Profound suits enterprise teams that need SOC 2, GDPR, and CCPA compliance alongside AI visibility data.

AthenaHQ: Citation engine paired with content optimization workflow

AthenaHQ is the citation-focused AI visibility platform that pairs cross-platform tracking with content optimization recommendations, monitoring 8+ AI engines including ChatGPT, Gemini, Perplexity, AI Mode, AI Overviews, Claude, and Copilot. The proprietary Athena Citation Engine analyzes citation probability patterns across models and suggests specific content changes that increase citation likelihood. AthenaHQ's unlimited-seat pricing and integrated content workflow suit content teams that want measurement and production tools in one place.

OtterlyAI: Pure-play AI brand visibility tool with the highest sentiment score in the category

OtterlyAI is the pure-play AI brand visibility tool ranked in the Leaders quadrant of the 2026 GEO and AEO platform comparisons, with the highest sentiment score among major platforms. The tool tracks ChatGPT, Claude, Perplexity, and Gemini with a focus on actionable recommendations rather than dashboard depth, including advanced filtering and prompt-level reporting. OtterlyAI fits agencies and SMB teams that prioritize clear next steps over enterprise-grade analytics depth.

Peec AI: Lean LLM-native visibility tool with prompt-level tracking

Peec AI is the lean, LLM-native visibility tool built around prompt-level tracking, with daily prompt execution across major AI models and segmentation by region, prompt tag, or audience persona. Customer reports include posts ranking for targeted ChatGPT and Perplexity prompts within 24 hours of optimization changes, with documented 5x year-over-year traffic increases from LLM referrals. Peec suits marketing teams that want fast, simple visibility data without the enterprise overhead.

Semrush AI Visibility Toolkit: Integrated AI citation tracking inside the broader SEO platform

Semrush ships the AI Visibility Toolkit at $99 per month, tracking brand citations across ChatGPT, Perplexity, Google AI Mode, and Gemini alongside the broader Semrush platform's keyword, ranking, and competitive intelligence data. The integration is the differentiator: AI citation gaps appear next to traditional ranking gaps in the same dashboard, which lets teams correlate organic ranking changes with AI visibility shifts. Semrush fits teams already on the platform that want consolidated visibility without bolting on a separate tool.

HubSpot AEO: Free-tier AI visibility integrated with the HubSpot stack

HubSpot AEO offers a free 28-day trial with 25 prompts tracked across ChatGPT, Gemini, and Perplexity, paired with visibility scoring, prompt tracking, citation analysis, and prioritized recommendations integrated directly into the HubSpot CRM. The tool was built after HubSpot ran AEO on its own brand and saw conversion lift from AI-referred leads at 3x traditional search rates. HubSpot AEO suits teams already on the HubSpot stack who want AI visibility data alongside marketing and sales workflows.

Evertune: Real-time competitive intelligence for fast-moving categories

Evertune is the real-time competitive intelligence layer for AI visibility, with rapid detection when a competitor begins appearing in AI responses for queries where they previously didn't. The speed of detection matters most in competitive markets where citation positions shift frequently, and Evertune's monitoring cadence catches changes most monthly tools miss. The platform suits brands in fast-moving categories where waiting a week for citation data is too slow.

Adobe LLM Optimizer: Enterprise AI visibility inside the Adobe stack

Adobe LLM Optimizer integrates AI visibility tracking into the Adobe Experience Cloud, with multi-platform monitoring across ChatGPT, Google AI Mode, Copilot, and Perplexity tied to Adobe's existing analytics, content management, and personalization stack. The platform measures agentic traffic patterns and connects visibility metrics to traffic, engagement, and conversion outcomes through Adobe's attribution layer. Adobe LLM Optimizer suits enterprise teams already on the Adobe stack that want AI visibility consolidated with the rest of the marketing measurement layer.

Alhena: Product-level AI visibility for e-commerce brands

Alhena is the AI visibility tool purpose-built for e-commerce, tracking which specific SKUs appear (and don't) across ChatGPT, Gemini, Perplexity, and other AI shopping answers rather than just brand-level mentions. The platform identifies products with strong on-site performance but low AI visibility, and connects AI shopping recommendations back to actual revenue through dedicated attribution. Alhena fits e-commerce brands where AI visibility translates directly into purchase decisions and product-level data matters more than brand mentions.

Where to Start

For enterprise teams with deep analytics needs, Profound and Adobe LLM Optimizer cover the full data stack. Content teams looking for citation tracking with built-in optimization should start with AthenaHQ, while agencies and SMB teams will find OtterlyAI or Peec AI faster to deploy. If you're already on Semrush or HubSpot, the integrated visibility toolkits in those platforms reduce switching costs significantly. For e-commerce brands, Alhena's product-level tracking is the only tool in the category that connects AI visibility directly to SKU-level revenue. Our Agentic SEO Playbook covers how the same architecture extends from visibility tracking into agentic content production.
