In plain words
CTRL-F is an Android app that lets users search text within printed documents using their phone's camera. It captures images of physical pages and enables keyword searching across the scanned content. The app is designed for people who need to quickly locate information in papers, books, or other printed materials without manually flipping through pages. It combines mobile photography with text recognition to streamline document research.
