DataLine is an AI-driven open source platform for data exploration and visualization. It allows users to connect to databases and generate tables, charts, and dashboards through natural language chat. The tool prioritizes privacy by processing data locally on the user's device, ensuring no data leaves the machine. It supports multiple databases including Postgres, MySQL, SQLite, MS SQL Server, Snowflake, and BigQuery, as well as CSV and Excel files. DataLine is suitable for both non-technical users who want to query data without SQL knowledge and developers seeking a high-quality text-to-SQL solution. Key features include data visualization, local LLM support (coming soon), and open-source availability.
