# Prifina > Prifina builds the AI Twin: a reliable, controllable representation of a person, powered by knowledge they own, for the people and audiences they choose. An AI Twin answers questions the way you would, using only the knowledge you add and the permissions you set. You choose what it knows, who can talk to it and where its answers are processed. Prifina keeps it running and keeps your knowledge safe. ## Pages - [Home](/): What an AI Twin is, what you control and how it grows. - [Ownership](/ownership): Data ownership, sovereignty, region and model choice. - [Getting started](/getting-started): The steps from account to a published AI Twin link. - [Pricing](/pricing): Plans for individuals and Pro features such as custom domain and API. - [Questions](/questions): Frequently asked questions about AI Twins, privacy and data. - [Blog](/blog): Articles on personal AI, data ownership and AI Twins. - [Guide](/guide): How to prepare knowledge and get the most out of an AI Twin. - [Contact](/contact): Get in touch with Prifina. ## Who it is for - [Speakers](/speakers): AI Twins for speakers and their audiences. - [Authors](/author): AI Twins for authors and readers. - [Executives](/executive): AI Twins for leaders scaling their presence. - [Athletes](/athletes): AI Twins for athletes and fans. - [Events](/events): AI Twins for event organizers and attendees. - [Groups](/groups): AI Twins for teams and organizations. - [Education](/ai-twins-in-education): AI Twins for teaching and learning. ## Developers - [For developers](/for-developers): Building with the AI Twin platform. - [Developer hub](/dev): API documentation and integration guides. ## Optional - [Ambassadors](/ambassadors): The Prifina ambassador program. - [Privacy policy](/privacy): How Prifina handles personal data. - [Terms of use](/terms-of-use): Service terms. - [Acceptable use](/acceptable-use): Platform guidelines.
