If you've ever sent the wrong resume version to a company or lost track of which bullets you used where, this helps you stop the chaos. It builds a master resume with every achievement and bullet point you've ever written, then maintains an organized folder structure for tailored versions with sensible naming conventions like LastName_Role_Company_Date. The real win is the workflow: you always pull from the master instead of editing random copies, and you track which version went to which company in a simple spreadsheet. It's not revolutionary, just systematic, which is exactly what you need when you're applying to dozens of places and can't remember if you emphasized leadership or technical skills in that Google application.
