Mosfet IA is an AI-visibility platform that measures and improves how AI assistants — ChatGPT, Gemini, and Perplexity — answer about a brand. It runs weekly, prompt-level measurements across these engines to show where a brand is mentioned, recommended, and cited when buyers ask category questions, and where it is absent. Every answer is stored with a date and a verifiable fingerprint, so results stay auditable over time. The platform tracks a visibility index and share of presence by engine and topic, identifies the questions and competitors that matter, detects gaps, and generates the content needed to close them. Teams can run it in self-service or have Mosfet IA operate it as a managed service.
