PDF Search PRO: Book Library

PDF Search PRO turns everything you own into a library you can search in the
time it takes to type. Books, textbooks, lecture notes, contracts, papers and
manuals, all ranked by how well they answer you. Ask a question in plain words
and get an answer, with the exact pages it came from.

Everything is included from the first launch. No subscription, no in-app
purchases, no ads.

Built for people who live in documents: students, lawyers and researchers.


ASK YOUR LIBRARY ANYTHING

AI Chat answers questions about your library in plain language. Ask "can I end
my lease early?" and it searches your documents, reads the pages that matter,
and answers, citing the page each fact came from so you can check it yourself.

• Chat about your whole library, or the one document you are reading
• Every answer carries page references you can tap
• Conversations are saved, so you can pick one up later
• Runs on your device, or on Apple's Private Cloud Compute

AI Chat needs Apple Intelligence: an iPhone 15 Pro or later, or an iPad with an
M-series chip, running iOS 26 or later.


A FINDER THAT RANKS, NOT JUST MATCHES

Ordinary search tells you a word exists somewhere. PDF Search PRO scores every
page on how well it answers you: where the words appear, how close together
they are, whether they land in a heading. The strongest pages come first.

• Every ranked result, grouped by book or document
• Jump straight to the page, your words highlighted in context
• Search everything at once, or narrow to a folder or tag
• Search only the table of contents, match case, skip duplicates
• Export and share results


LANGUAGE, NOT JUST LETTERS

The indexer understands the shape of a word. Look for "hike" and find
"hiking"; look for "children" and find "child". Plurals, stems and near
matches are covered too.


WORDS LOCKED IN IMAGES

Text recognition reads photographed pages, scanned contracts and screenshots
of slides, and adds every word to your index. A photo of a page becomes as
searchable as the page itself, in every language your device supports.

The built-in scanner turns paper, notes and cards into PDFs and files them
with everything else, searchable from the moment they land.


NOTES, HIGHLIGHTS AND MARKUP

• Highlight, underline and strike through while you read
• Bookmarks with notes, gathered in one place across every book
• A document's table of contents, for moving around a long textbook quickly


AN ORGANIZER FOR A LARGE LIBRARY

• Folders on device or in iCloud, plus any folder or file you point it at
• Tags, to cut across folders however you think
• Index status at a glance: what is indexed and what is queued
• PDFs alongside Word and PowerPoint, Pages and Keynote, rich text, plain
text, source code and saved web pages


YOUR MAC, IN YOUR POCKET

Run PDF Search on your Mac and sync over Wi-Fi with a single click. Documents
come across with their index intact, so your iPhone or iPad does not have to
do the work twice.
