What's the difference between GEO Score and AI Visibility Checker?
GEO Score grades how well a single page is optimized for AI search engines (a 0–100 score across Citability, Structure, Definitions, Takeaways, and Citations). The AI Visibility Checker measures whether your domain is actually cited by ChatGPT, Perplexity, and Google Gemini today. GEO Score is forward-looking — what to fix on a page; AI Visibility Checker is current-state — who's citing you right now.
Are these tools free?
Yes. Both are free with no signup required for the basic results. The AI Visibility Checker shows the ChatGPT result for free; email capture unlocks the deeper Perplexity + Gemini result. The GEO Score Checker is fully free with no email required. For advanced AI content optimization and real-time scoring across your full site, Frase subscriptions start at $38/month.
Which AI engines does the AI Visibility Checker test?
ChatGPT for the free tier-1 result. After email capture, we also probe Perplexity and Google Gemini using AI-search-style phrases generated for your domain's industry.
How accurate is a single-domain probe?
Each AI Visibility probe runs three AI-search-optimized phrases generated for your domain. Cited/not-cited reflects a single moment in time — AI search engines update their indexes constantly, so results can shift week to week. Use it as a directional check, not a permanent verdict.
Do I need to sign up to use either tool?
No. The GEO Score Checker requires no signup. The AI Visibility Checker shows your ChatGPT result without signup; only the deeper multi-engine result gates behind email capture.
