Vanna AI Freemium

Query Databases in Plain English with Vanna AI's Text-to-SQL Assistant

What is Vanna AI?

Vanna AI is an open-source Python framework for text-to-SQL generation. It connects to your database, learns from your schema, documentation, and historical query-answer pairs, then translates natural-language questions into accurate SQL that runs against your data.

Because Vanna AI trains on your specific database context rather than relying only on a generic model, it produces far more reliable results for real business schemas. Teams embed it into chats, notebooks, and internal tools to let non-technical users explore data safely.
