# Cytix AI > Cytix AI is the visibility platform for AI search — "GEO" (Generative Engine Optimization). We measure and improve how AI assistants (ChatGPT, Gemini, Claude, Perplexity and Copilot) mention and cite brands when buyers ask them. Where SEO ranks links, GEO gets a brand into the answer itself. ## What we do - Measure brand visibility across five AI engines using real category questions (25 prompts × 5 engines, re-measured monthly). - Agent Access Audit: verify crawlability, network reachability and no-JavaScript readability — what a robots.txt alone will not reveal. - Competitive benchmark: show which sources AI trusts in a category and where a brand is missing. - Prioritized action plan plus a human review session; monthly re-measurement and verification. ## What we are not - Not an SEO tool that ranks links — GEO is complementary, focused on citations inside AI answers. - We measure from the outside, the way AI engines do. We never need a client's site credentials or account access. ## Focus - Spanish-speaking markets (LatAm and Spain) are a primary focus; measurement is done in the buyer's language. English markets are supported. ## Pages - Home (Spanish, primary): https://cytixai.com/ - Home (English): https://cytixai.com/en/ - This page, for AI agents: https://cytixai.com/para-la-ia - Free analysis (enter a domain): https://cytixai.com/analyze ## Engines covered ChatGPT, Gemini (the engine behind Google's AI answers), Claude, Perplexity, Copilot (Microsoft/Bing). ## Contact Website: https://cytixai.com
