Designed around trust

Useful without becoming invasive.

Clear information architecture, honest transformations, safe previews, and no document content sent to analytics.

Local-first privacy, visible in the interface

The workspace always tells users when a file is opened locally, what transformation is being performed, and whether an export changes the original.

Honest rendering

Table mode appears only when a real record structure exists. Invalid rows remain visible instead of disappearing.

Real exports

PDF, CSV, XLSX, TXT, SQL, HTML, SVG, and PNG outputs use the correct file type — not a renamed extension.
