FAQ
CogNerd is an AI search visibility platform that helps brands monitor, optimize, and grow their presence across AI-powered search engines like ChatGPT, Claude, Gemini, Perplexity, and more. Instead of tracking Google rankings, CogNerd tracks whether AI models cite, recommend, or mention your brand when users ask relevant questions.
CogNerd currently monitors 10+ AI platforms including ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Perplexity AI, Microsoft Copilot, Grok (xAI), DeepSeek, You.com, and more. We add new platforms as they reach meaningful user adoption.
Traditional SEO tools track keyword rankings in Google's blue-link search results. CogNerd is built for the era of AI search — where users ask questions and AI systems provide synthesized answers. We track brand citations in AI responses, identify gaps, and generate the structured content (llms.txt, schema.org, FAQs) that AI models use to reference your brand.
