PDF Beacon: Quick Search

PDF Beacon is an offline-first PDF library built for fast text search — now with a built-in study and language-learning companion.

Import PDFs into your on-device library, organize them in folders, and search across your documents. Open a match and PDF Beacon jumps straight to the page, highlights the occurrence, and lets you move through every result with previous/next navigation. Full-line search results show the surrounding sentence so you pick the right hit fast. A draggable page scrubber makes long PDFs quick to navigate.

Scanned PDFs are supported with on-device OCR. Search works after OCR completes — your document images and extracted text stay on your device.

LEARN WHILE YOU READ
• Highlight all occurrences of a word and attach one translation and note to the whole group
• Tap a saved highlight to instantly see its translation and your note
• Remove many matching highlights at once, undo the change, or keep the learning note
