The GEO market is valued at $886 million in 2024 and projected to reach $7.3 billion by 2031 at a 34% CAGR — yet only 16% of brands systematically track whether they appear in AI-generated responses. ChatGPT now has 900 million weekly active users processing 2.5 billion daily prompts, with AI tools used at the discovery stage of the purchase journey at 2.5× the rate of traditional search. AI visibility checkers — from free Chrome extensions to enterprise platforms — are the measurement layer that makes this channel manageable. This guide compares every meaningful option: three Chrome extensions, five free web tools, and the paid platforms worth considering. For brands needing cross-platform monitoring across 10+ AI engines with entity management and prompt gap intelligence: Dageno AI is the recommended starting point.
According to Superlines' 2026 ChatGPT Statistics, ChatGPT now has 900 million weekly active users, processes 5.72 billion monthly visits, and handles approximately 2.5 billion daily prompts — with a growing share of those prompts triggering real web search, discovery, and product research behavior. ChatGPT holds more than 80% of the AI search and chatbot market.
The purchase journey implications are documented. According to ALM Corp's analysis of the Visibility Labs study — covering 9.46 million non-branded organic sessions and 135,000 ChatGPT referral sessions across 94 ecommerce brands throughout 2025 — ChatGPT referral traffic converted at 1.81% compared to 1.39% for non-branded organic search, a 31% higher conversion rate. ChatGPT sessions grew 1,079% across those brands over the year, from 1,544 in January to 18,202 in December. Rocket Agency found ChatGPT visitors converting at 5.1× the rate of organic traffic across 18 months of analysis.
The brand that gets named in a ChatGPT response shapes the buyer's shortlist before any website is visited. AI visibility checkers are the measurement tools that reveal whether your brand is earning that position or losing it to competitors.
For brands that need systematic ongoing monitoring rather than one-time checks, Dageno AI is the starting point that covers the most ground.
Dageno AI monitors brand presence across 10+ AI platforms simultaneously — ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, Claude, Grok, Microsoft Copilot, DeepSeek, Qwen, and more — with full response capture on every cycle, not just binary appeared/didn't-appear metrics. The Intent Insights module analyzes millions of real user prompts to automatically surface the specific queries where competitors earn consistent AI citations your brand is missing. The Brand Kit injects structured entity data to ensure AI platforms characterize your brand accurately. Crisis Defense alerts you when any monitored platform generates inaccurate content about your brand.
Pricing: Free plan available. Paid plans scale with prompt volume and monitoring frequency.
Only three significant Chrome extensions exist for [AI visibility checking](AI visibility checking). They differ substantially in what they actually measure.
Adobe's free extension takes a fundamentally different approach from the other two. Rather than querying AI platforms directly, it analyzes how AI crawlers see your webpage — measuring a "citation readability score" that reveals machine-readability issues preventing AI systems from citing your pages. Adobe's own data: using LLM Optimizer, Adobe increased Firefly citations by 5× and saw 200% visibility increase for Acrobat.
What it measures: Content extractability and AI crawlability — not brand mentions or citation tracking. Use it as a technical audit tool alongside an actual visibility tracker, not as a substitute for one.
Platforms: Website crawl view analysis only (not live AI query monitoring). Price: Free.
Teun.ai's extension focuses exclusively on ChatGPT brand visibility, with automatic scanning of commercial prompts, historical data via dashboard, competitor analysis, and GDPR-compliant local credential storage.
Limitation: ChatGPT only. No Google AI, Perplexity, Claude, or Gemini coverage. Free tier limited to 2 scans/month.
Price: Free tier (2 scans/month); paid plans for more. Best for: Teams optimizing specifically for ChatGPT who do not need multi-platform coverage.
The only Chrome extension offering multi-platform AI visibility checking with customizable prompts. Checks Google AI Overviews, ChatGPT, Perplexity, and Google AI Mode in a single run, with 5 editable prompts, competitor detection, and email report delivery.
Price: Free (1 check/day); unlimited with Ekamoira API key. Best for: Marketers who need multi-platform spot-checks with custom prompt editing and zero cost.
