Dataline is an AI-driven data analysis and visualization tool that enables users to interact with their private business data sources through natural conversations. Currently supporting data sources like CSV, Postgres, MySQL, and SQLite, Dataline offers a localized solution for data exploration.
Notably, Dataline prioritizes data privacy and security by default, hiding user data from large language models within each project, ensuring maximum protection.

Let’s take a closer look at this powerful tool.
Easy Installation
Installing Dataline is relatively straightforward:
- Windows users can directly download the installation package
- Mac users can use the Brew command for installation
- Linux users need to install via Docker
Additionally, Dataline supports local execution by following the provided commands for frontend and backend setup.
For this demonstration, I used the Windows version, simply double-clicking the startup file to run the Dataline service locally.
Interactive Browser Interface
Once the service starts, users can interact with Dataline through their web browser. Begin by entering your OpenAI API Key. Note that custom base_url is not currently supported, which is a limitation. Tech-savvy users can modify the source code, while others may need to wait about two weeks for the author to provide a version with custom base_url support.
The interactive interface allows users to ask various questions and engage in chat-style interactions with the system.
Connecting Data Sources
To start using Dataline, users first need to create a new data connection.
The system supports multiple data sources, including various databases. Users simply provide the data source name (DSN) and related information to establish the connection.
Dataline also supports uploading CSV format files or importing SQLite files. For this demo, we used a default dataset that comes with the project.
Conversing with Data
After creating an instance, users can begin conversing with their data. The system provides sample questions to guide users on how to ask.
In practical use, we can request the system to answer in Chinese and pose various data analysis questions.
For example, we can analyze the revenue generated by each store.
Dataline generates the corresponding SQL query statement and returns the query results.
Visualizing Results
Taking it a step further, we can ask the system to create charts to visualize these results. The charts are not only visually appealing but also directly downloadable for use.
Advantages of Dataline
One of Dataline’s major advantages lies in its extensive data source support and ease of use. It supports multiple mainstream database formats and is plug-and-play. This makes it particularly suitable for technical and non-technical personnel who need to quickly explore data, as well as backend developers looking to accelerate database queries and exploration.
Considering its security and open-source nature, Dataline is very well-suited for enterprise use. It stores all content on local devices without relying on cloud services. By default, user data is not exposed to large language models, with all processing done locally. Of course, if the data is not particularly sensitive, users can choose to disable this feature and allow data to be open to large models.
Powerful Functionality
Dataline’s functionality is very powerful, including executing queries, generating charts, and more. Users can leverage these features to quickly build reports. For data analysts, Dataline is a tool that can significantly improve work efficiency. It not only supports generating and executing SQL queries from natural language but also allows users to modify and customize these query statements. Modified queries can be re-run, providing great flexibility for data exploration.
Conclusion
Overall, Dataline is a highly convenient and powerful data analysis and query tool, especially suitable for data analysts and backend programmers who frequently interact with databases. If you’re interested in Dataline, feel free to install and try it out following the instructions above.
