Compare a "needs" spreadsheet against a ZIP folder to instantly see what's found, what's a possible match (named differently), and what's truly missing. Everything runs in your browser — nothing is uploaded anywhere.

Everything happens locally in your browser using JavaScript — your files are never uploaded to a server. This file can be saved and emailed/shared as a single .html file; anyone can open it by double-clicking, no installation required (an internet connection is needed the first time to load two small helper libraries).
