What's New in PDF Search

9.0

September 19, 2026

Version 9.0 — the biggest release PDF Search has had. AI CHAT Ask your documents a question in plain words and get an answer back, with the exact pages it came from. • Chat about your whole library, or about the one document you are reading • Every answer cites its pages — tap a reference to open that page and check it • AI Chat searches with PDF Search's own ranking, so it reads the pages that actually answer you rather than the first ones it finds • Conversations are saved, so you can pick one up days 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. It is part of Pro. A COMPLETE REDESIGN Every screen has been rebuilt. • A new home screen that puts search and your locations first • Search results grouped by document, with each matching page and its rank, and a progress panel while a long search runs • Redesigned document rows with page previews and clear indexing status • Rebuilt tags, bookmarks and index status screens • Empty states that tell you what to do next instead of showing nothing • New typography, colour and iconography throughout SETTINGS, REWORKED Settings have been reorganised into General, Index, Search and Text Recognition, and now scale properly with your preferred text size. FASTER, LIGHTER Page previews are cached, indexing yields to whatever you are doing, and scrolling a large library stays smooth. Memory use during indexing is substantially lower. ALSO IN THIS RELEASE • Purchases are verified more reliably, and restoring works more consistently • A privacy manifest, declaring exactly what the app uses and why • Many smaller fixes across indexing, navigation and the reader Thank you for using PDF Search.

Mac sync broken

The app is great, but in this latest update the sync with Mac app feature appears to be broken.

Constantly crashes

It’s wonderful, once the app catalogs the publications, but I have many hundreds of books I want to catalog and it only does a few at a time and then crashes. 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.

broken and no support

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.
