# Get Started with Rasa

> Understand the Rasa Platform, explore CALM, and choose how to build your first conversational AI agent.

Rasa helps teams build conversational AI agents that use large language models
for natural conversations while keeping business logic explicit and testable.

## Understand the Rasa Platform

The Rasa Platform gives developers and conversational AI practitioners two
interfaces for working on the same agent. Both interfaces use
[CALM (Conversational AI with Language Models)](/docs/learn/concepts/calm), Rasa's
approach for using large language models to understand a conversation while
flows define the business logic an agent must follow.
