PDF Search — find it, and ask about it PDF Search reads every word of every document you own and makes it findable in the time it takes to type. Then it goes further: ask a question in plain words and get an answer, with the exact pages it came from. Built for people who live in documents — students, lawyers and researchers. ASK YOUR DOCUMENTS ANYTHING — NEW 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. SEARCH THAT RANKS, NOT JUST MATCHES Ordinary search tells you a word exists somewhere. PDF Search scores every page on how well it answers you — where the words appear, how close together they are, whether they land in a heading — and puts the strongest first. • Results grouped by document, with every matching page and its rank • Jump straight to the page, your words highlighted in context • Search everything at once, or narrow to a folder or tag • Export results to share or keep LANGUAGE, NOT JUST LETTERS Indexing uses tokenizing and lemmatization, so search understands the shape of a word. Look for "hike" and find "hiking"; look for "children" and find "child". Stems and near matches are covered too. WORDS LOCKED IN PICTURES Built-in text recognition reads photographed receipts, scanned contracts and screenshots of slides, and adds every word to your index — so a picture of a page is as searchable as the page itself. It covers every language your device supports. The built-in scanner turns paper documents, notes and cards into PDFs, reads them as it goes, and files them with everything else — searchable from the moment they land. MORE THAN PDFS Index PDFs alongside Microsoft Office documents (Word, PowerPoint), iWork files (Pages, Keynote), rich text, plain text and logs, source code, and pages saved from the web. Turn any format off to skip it. KEEP A LARGE LIBRARY IN ORDER • Folders on device or in iCloud, plus any folder or file you point the app at • Tags, to cut across folders however you think • Bookmarks with notes, gathered in one place across every document • A document's table of contents, to move around a long file quickly • Highlights and annotations while you read • Index status at a glance: what is indexed, what is queued 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 need not do the work twice. PRIVATE BY DEFAULT Indexing and search happen on your device. Your documents stay yours. FREE AND PRO The free version indexes and searches your documents and opens the top-ranked result. Pro unlocks everything else: • AI Chat, with page references • Search inside images and scans • Scan paper to PDF • Plurals, stems and near matches • Every ranked result, not just the first • Export, tag and de-duplicate Pro comes as a monthly or annual subscription, or a one-off lifetime unlock — one payment, yours for good, no renewals.

To try to get around this limitation, I got the iPad Pro with maximum RAM, and it helped some, but still crashes every few minutes. ### 1/5 — broken and no support *2026-05-06, version 8.31* this app used to be good, but now if you’re scrolling documents, it repeats pages and skips pages, and you can never see them. it jumps all over the place when you’re scrolling back and forth between pages. I can’t be confident in any of the search results anymore because sometimes the result is on a page that it just refuses to display. It just displays two of the same pages in a row, skipping the real next page altogether. it just shows the previous page twice in a row, and skipping the page with the actual result. App support is nonexistent. I’ve emailed numerous times and never even get a reply let alone an acknowledgement of problems. ### 1/5 — UPDATE IT PLEASE *2025-11-27, version 8.31* Useless. App cant even index without crashing ### 1/5 — Used to work *2025-10-24, version 8.31* App can’t even find my docs stored in itself on iCloud anymore / no support when I email & no updates in a year + ### 5/5 — Gute und stabile Software *2024-08-19, version 8.31* Habe über die letzten Jahre hinweg circa 50.000 PDF Dateien gesammelt. Manche manche der Dateien enthielten mehr als zehn Seiten. Es wurde jeder Fachbegriff, das als Schlagwort nach der Indexierung eingegeben wurde, wieder gefunden. Die Suche dauerte auf dem iPad mit M1 Prozessor. Circa 2-3 Sekunden. Ich bin sehr zufrieden. ### 5/5 — App Crash When It Downloads From Google Drive And Index *2024-06-21* The app is excellent overall, but I hope one annoying issue can be fixed. When I connect my Google Drive to the app, it downloads all of my PDFs and other documents and indexes them locally. I have a lot of files, and when it downloads and indexes them simultaneously, the app crashes constantly. It's really inconvenient having to reopen the app again and again. I hope this issue can be fixed soon. Thanks! ### 5/5 — I love this App *2024-06-14, version 8.31* wenn man zu viele pdfs hat ergibt die app alle möglichkeiten diese entspannt zu durchsuchen . total effizient. Danke an den Entwickler ### 5/5 — Ottima! *2024-05-14, version 8.28* Uso PDF search quasi quotidianamente su Mac e iPhone. La trovo l’ideale per ritrovare i passaggi degli articoli che mi servono senza dover cercare come un disperato tra i vari abstract quello giusto. Generalmente il primo o il secondo risultato sono quello che sto cercando. Se funzionasse anche come reference manager e avesse pure una specie di riassunto per ogni articolo sarebbe l’app divina, ma visto che non lo fa sono costretto ad avere i vari pdf in cartelle diverse. ### 5/5 — Excellent! *2024-05-06* I hope the developers keep adding features because the app is amazing. I use it to search for PDF documents, such as books, and is very accurate. Specially I like the search across books series where I can just type a few words of an event or character I barely remember (from some books ago in a series) and will search and find the paragraphs with the key words typed. **Developer response:** Thank you for your kind review 🙏 ## Frequently asked questions about PDF Search ### What does PDF Search do?
