When doing research or even just trying to find a particularly memorable phrase in a PDF document on a computer, the control-F document search function is an incredibly convenient tool. However, with a paper document, readers can only rely on their eyes to find a given word -- unless they've downloaded the 'CTRL-F' app. CTRL-F lets users scan any text, be it a page from a book, a user manual, a magazine, or anything else and turn that text into a searchable file.
The free document search app is intuitive to use, since no aspect of the operation requires leaving the app's interface. Rather than taking a picture and uploading it to CTRL-F, the app lets users access their camera and scan documents immediately. Within a few seconds, CTRL-F makes the scanned page searchable.
This document search app adds an incredible amount of convenience to the lives of students and researchers who often find themselves buried in old-fashioned books.
