# Bruin

> Bruin is an open-source, AI-powered data platform. Its Apache 2.0 CLI handles data ingestion (with ingestr), SQL and Python pipelines, quality checks, column-level lineage, catalog, and orchestration; on top of that governed data, an AI data analyst answers questions in Slack, Microsoft Teams, Google Chat, WhatsApp, Discord, Telegram, email, or the browser, builds dashboards from a prompt, and runs scheduled agents. Pipelines are plain files in your own Git repository and data stays in your own warehouse; Bruin Cloud is the optional managed layer.
