# Rasa

> Rasa is an open-core conversational AI framework for enterprises that natively leverages generative AI (CALM — Conversational AI with Language Models) to build reliable text and voice assistants. Rasa Pro is the pro-code framework; Rasa Studio is the no-code UI. The runtime is self-hosted and exposes an HTTP API plus a custom-action SDK.
