GapCite is an AI visibility (GEO/AEO) platform that shows whether ChatGPT, Perplexity, Gemini and Claude recommend your brand when buyers ask real questions. It tests unbranded, buying-intent questions, not "tell me about your brand" prompts, which only prove the AI knows you exist. Every question is checked against the real engines before it counts, so a bad question never shows up as a false "invisible" result. A free scanner checks Perplexity and Gemini in 30 to 90 seconds, no signup needed. Paid plans (from $29/mo) track up to 8 engines weekly, benchmark competitors, and give a plain-language list of what to fix.
