DataLine vs ThoughtSpot

DataLine is an AI tool for querying data in natural language and turning results into tables, charts, dashboards, and reports. It can generate and execute SQL from prompts, then lets users edit, save, and rerun the SQL results; chart queries can also be edited and refreshed. Listed connections include Postgres, Snowflake, MySQL, Azure SQL Server, Microsoft SQL Server, Excel, SQLite, CSV, and sas7bdat. The project is open source under GPL-3.0 and offers a free plan, with binaries and a Docker image for installation. It runs on Linux, macOS, Windows, web, and self-hosted environments. The maker says data is accessed and stored on the user's device rather than in cloud storage, and the README says data is hidden from the LLMs used by default. Docker is described as more suitable for business use. Self-hosted mode has basic username and password authentication, while the executable does not; the current setup supports one user. Excel sheets are imported as separate tables, and the import fails if any sheet fails.
