# Rankfor.AI > Rankfor.AI helps brands get named in AI answers when buyers ask about their category, and helps publishers sell sponsored content for AI discovery. It works through three capabilities: intelligence about what AI assistants answer and which sources they cite, content written for specific buyer personas from facts the brand approves, and infrastructure that publishes that content where AI assistants read it. Rankfor.AI measures AI visibility with a fixed protocol: the same buyer questions, asked several times on each AI assistant, with a baseline reading before any change and a follow-up reading after it. AI assistants choose their own sources, so Rankfor.AI makes no promise of a citation, a recommendation or a position in an answer. Sponsored content carries a disclosure, and the publisher approves every piece before it goes live. ## Products - [Rankfor.AI platform](https://www.rankfor.ai/our-solutions): the Rankfor® Index, a 0 to 100 score for how AI assistants see a brand, plus AI visibility measurement, buyer personas, content plans and competitive intelligence for a brand account. Every plan measures Gemini and ChatGPT; Enterprise adds Claude, Grok, Perplexity and Mistral. - [Answer Trail](https://www.rankfor.ai/does-ai-recommend-your-brand): a free check that records the searches an AI assistant runs and the sources it reads before it recommends a brand for a buyer question, and shows whether the brand is recommended, mentioned but not backed, or invisible. - [Book a call about AI Ads](https://meetings-eu1.hubspot.com/dmitrij/rankfor): AI Ads is sponsored content for AI discovery, sold by publishers to advertisers. Rankfor.AI turns the advertiser's approved brief into content for specific buyer questions and delivers it on an ai. subdomain of the publisher's own website, so the reader-facing website stays unchanged. Campaigns are scoped per publisher and brief. - [AI Direct Sales](https://www.rankfor.ai/is-your-sales-team-in-ai): a hosted page for each customer-facing salesperson, structured so AI assistants can read and cite it. - [AI Business Cards](https://www.rankfor.ai/products/pages-ranking-in-ai-for-consultants): a one-page professional website built for AI, for sole practitioners such as accountants, legal and tax advisors, developers and consultants.
