Field notes
The tool list is organized around practical handoffs: submitting a payslip to a bank or tax office, sharing masked CSV data with a vendor, or preparing a photo for posting. The page says users can inspect browser Network activity during processing; its no-upload and local-processing statements are site claims, not independently verified by the supplied evidence.
