portia

Portia is an independent AI-powered data copilot that connects to data warehouses like Snowflake, BigQuery, PostgreSQL, or local files to profile tables, answer questions, visualize data, and build SQL data pipelines step by step. It records decisions in specs compiled to SQL, ensures data quality checks, and maintains a knowledge graph for column lineage and overlap. It integrates with the Claude Agent SDK and supports local AI models for enhanced data interaction.
