# Vouch > Vouch is a generative engine optimisation (GEO) tool that shows brands how AI assistants talk about them across a whole buying conversation, and where they drop out. - Vouch asks AI assistants the questions buyers ask, follows up the way a buyer would, and records where a brand is named, recommended or dropped, and which rival took its place. - Vouch tracks seven AI assistants: Claude, Gemini, ChatGPT, Perplexity, Google AI Overviews, Google AI Mode and Copilot. Threads run on Claude, Gemini, ChatGPT and Perplexity: three every 7 days, together, for each prompt, assistant and country where they are on. - A Thread is one buyer’s conversation with an AI assistant, six questions long: Discovery, Shortlist, Objection, Trust, Value and Decision. - The Vouch Rate is one number from 0 to 100: the average score of a week’s completed buying conversations, where a brand scores for each stage it survives and for being recommended at the end. - Every plan starts with a 14-day free trial. No card needed.
