What is Wren AI?

Wren AI is an open-source text-to-SQL solution based on natural language processing technology. It allows users to execute database queries using natural language questions, eliminating the need to write complex SQL code. It supports various databases and data sources, including PostgreSQL, MySQL, BigQuery, and CSV and JSON files. Wren AI's semantic engine understands business context, providing accurate query results and making data analysis simpler and more efficient. Wren AI integrates with various marketing and analytics tools, helping users quickly gain insights and take action from their data. Its open-source nature allows users to freely deploy and customize it to meet the needs of different users.

Wren AI's main functions

  • Natural Language QueryUsers ask questions in natural language, and Wren AI automatically converts the questions into SQL queries.
  • Multiple data source supportIt supports connections to various databases and data formats, such as PostgreSQL, MySQL, CSV, and JSON.
  • Semantic understandingBased on the semantic engine, the understanding of business context is improved, and the result query is more accurate.
  • Data integrationIt can integrate data scattered across different systems and formats, providing a unified view for customers.
  • Data export and visualizationIt supports exporting query results to tools such as Excel and Google Sheets for further analysis.
  • SecurityTo ensure the security of user data, only metadata is used for querying, and no actual data is transmitted.

Wren AI's technical principles

  • Natural Language Processing (NLP)Wren AI uses NLP technology to parse users' natural language queries. The queries are converted into a machine-understandable format, generating corresponding SQL queries.
  • Semantic EngineWren AI's semantic engine is at its core, understanding the database's metadata and business terminology, and mapping natural language queries to the database's query language.
  • Vector DatabaseWren AI uses vector databases to process and retrieve data relevant to user queries. Vector databases can efficiently process and compare semantic search queries.
  • Large Language Models (LLM)Wren AI integrates large-scale language models to enhance its ability to understand and generate SQL queries. The models are trained to understand complex language structures and contexts.
  • Modeling Definition Language (MDL)Wren AI uses MDL to handle metadata, schema, terminology, data relationships, and the logic behind computations and aggregations. This reduces repetitive coding and simplifies data connections.
