Features
Read full description

Supports PostgreSQL, MySQL, and SQLite. 100% local and open-source. Get tailor-made queries from a schema-aware AI assistant: Copilot generates queries based on your database schema, including tables, columns, enums, constraints, and more. Rows are never passed to Copilot. Insert, update, and delete with ease: Generate SQL to modify your data with an intuitive user experience. Includes inputs optimized for each data type. Bring your data to life with charts: Easily generate line, bar, and pie charts from your SQL results. Also, Copilot will automatically suggest appropriate charts for generated SQL. Ask your database anything: Use natural language to get precise answers from your database. Get prompt suggestions and comfortably explore your data. Generate complex modifications tailored to your database schema. Thoughtful, customizable design: SmartQuery has a strong focus on user experience and accessibility. Adjust the theme and primary color to your liking. Security and transparency: SmartQuery is open source and 100% local—no accounts, no subscriptions, no cloud. When handling credentials and table data, there is no room for compromise. Here's how we keep things secure and private: - 100% local: SmartQuery runs entirely on your device. Credentials, connections, queries, and all data stay local. There is no cloud—no accounts, no syncing—so your database access never leaves your machine. - Your credentials, your device: Connection details and credentials are stored only on your device. Nothing is uploaded to our servers because we don't store user data—everything stays under your control. - Need-to-know basis: Your data is never stored or logged by us. When you use AI features, only the minimum necessary data (e.g. schema information) is sent to the AI provider—row data is never sent. - Web best practices: Data is always transferred via HTTPS and protected from man-in-the-middle attacks. The web app is protected against XSS and XSRF attacks and other web vulnerabilities.
