A minimalist, local-only JSON workbench built for data scientists and developers. It flattens deep nested JSON datasets into clean, column-typed Airtable-style grids with 60FPS virtualized scrolling. Features include 100% client-side AI semantic search using in-browser ONNX weights, instant df.describe() column statistical summaries, 10-bin header sparkline histograms, syntax auto-repair, and one-click clipboard exports directly to Pandas DataFrames. Zero data egress.
