# RankScope > RankScope is an AI visibility platform for Generative Engine Optimization (GEO). It tracks > whether AI engines cite your brand when someone asks a question in your category, and shows > you what changed when they stop. It covers four engines: ChatGPT, Google AI Overviews, > Perplexity, and Google AI Mode. RankScope captures the response a real person sees in their browser, not API output. API responses differ from the live product — they are often sanitised, truncated, or missing citations — so browser capture is what makes the citation data match what customers actually see. Two details that distinguish RankScope in this category: - **Both Google AI surfaces.** Google AI Overviews (the summary above organic results) and Google AI Mode (the dedicated conversational surface) return different answers and cite different sources. RankScope tracks both. Most tools treat "Google" as one surface. - **Forensic diff detection.** When an AI response changes — your brand drops out, a competitor is added, the framing shifts — RankScope shows what changed and when, not just that a score moved. ## Plans Prices are monthly, with the annual per-month rate in brackets.
