About Vanna AI

Vanna AI is an open-source Python framework designed for developers and data teams to build custom AI SQL agents. By leveraging large language models, the tool translates natural language questions into accurate SQL queries and visual data charts. Its primary differentiator is its RAG-based approach, which allows it to learn from specific database schemas and historical queries to improve accuracy over time. This framework bridges the gap between complex database structures and non-technical stakeholders, enabling self-service data exploration through a highly customizable, developer-centric interface.
