CtrlF Pro
Find Text in Any Book
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Find any word in any book instantly. Live camera scanner and photo library search with real-time highlighting.
CtrlF brings the power of Ctrl+F to the real world. Point your iPhone at any book, document, or printed material, type the word or phrase you are looking for, and watch matches highlight on screen in real time.
No more scanning page after page for that one quote or keyword. CtrlF uses advanced on-device OCR to recognize text and highlight every match instantly.
LIVE CAMERA SCANNER
Point your camera at any printed text and type to search. Matches appear instantly with bright highlights so you can spot what you need at a glance. Works in real time - no photo required.
PHOTO LIBRARY SEARCH
Already have a photo of the page? Import images from your photo library and search for text in them. Select any photo and find words instantly with the same powerful highlighting.
INSTANT MODE SWITCHING
Switch seamlessly between Live Camera and Photo Library. Tap the mode you need and start searching right away - no loading, no waiting.
MULTI-WORD PHRASE MATCHING
Search for exact phrases, not just single words. Find "quantum mechanics" or "United States" as complete phrases across any page. Unlike SearchCam which only finds one word at a time, CtrlF handles full phrases.
100% ON-DEVICE AND PRIVATE
All text recognition happens on your device. No internet required. No data sent to servers. Your privacy is fully protected. Unlike Google Lens, CtrlF works completely offline.
FLASHLIGHT SUPPORT
Working in a dim library or cafe? Toggle the built-in flashlight to illuminate the page without leaving the app.
