The idea
Marcel Pociot shows a macOS utility that watches Downloads and applies user-defined rules. The example recognizes an invoice and moves it into an appropriate folder with a useful name.
Inside the decision loop
File information + sorting rules
Identify the document category
Apply a file-system rule
What to take from it
A constrained classification can replace a complicated set of filename heuristics. Keep the move reversible and provide a review folder for documents that do not fit the available categories.
The post describes a prototype. It does not document how every file format is parsed. Jev needs text or structured context, so binary files need a separate extraction step.

This case is an editorial interpretation of a public community demonstration. It has not been reproduced or benchmarked by this publication.
