Vanna AI: SQL Generation with RAG

May 08, 2026

Vanna AI solves one of the most common business problems: allowing non-technical users to query complex databases using plain English. It is a specialized RAG framework designed specifically for accurate SQL generation.

Training on Your Schema

Unlike general-purpose LLMs, Vanna is "trained" on your specific database schema, documentation, and historical queries. This ensures that the generated SQL is not only syntactically correct but also understands the specific relationships and business logic within your data.

Self-Improving Accuracy

Vanna includes a feedback loop where users can verify or correct generated SQL. These corrections are fed back into the system, allowing the AI to learn and improve its accuracy over time, eventually becoming a highly reliable "AI data analyst" for your organization.
