Electron, DuckDB, MCP, PDF extraction, Recharts

A desktop application for data analysis that runs entirely locally — the data never leaves the machine. Querying local datasets with DuckDB, extraction from PDF, and visualisation.

Built for people who need insight into their own data without uploading it to a cloud service. That constraint is the product: it makes the tool usable in situations where sending the data somewhere is simply not an option.
