DataLine

DataLine turns data work into a conversation: ask questions in natural language and get ready-made tables, charts, and dashboards. It connects to your database locally, so your data isn’t sent to the cloud.

Ask questions instead of writing SQL

Instead of remembering column names and SQL syntax, describe what you need—for example, “Show sales by region for the last quarter” or “Find anomalies.” DataLine generates the query, runs it against your database, and visualizes the results in a clear format.

Local processing and open source

DataLine is built with privacy in mind: data stays on your machine and the database connection is direct. This reduces leakage risk and makes it easier to use in environments with strict security requirements. As an open-source project, it can be audited and, if needed, adapted to your infrastructure.

From quick answers to dashboards

Start with simple questions and gradually assemble full dashboards from the results. Editing queries and visualizations helps refine hypotheses and speed up analysis—especially when the work would otherwise require an analyst or SQL developer.
