## What is PDF Search?

Introducing PDF Search: The Ultimate Document Search Solution

PDF Search is a revolutionary app designed to search multiple documents at lightning-fast speeds. Unleash the power of AI to find any information within a vast array of documents in mere seconds. Our unique features such as Linguistic Search based on NLP, built-in OCR for Text Recognition, Document Scanning to PDF, Exportable Search Results, and Table of Contents search, will significantly enhance your document workflow productivity.

Experience the Difference

Unlike ordinary search tools that focus on keyword existence, PDF Search provides an intelligent search experience. Our cutting-edge algorithm assesses each page's relevance by analyzing factors such as keyword presence in titles - similar to a human search approach. This allows you to find the most pertinent pages across thousands of documents almost instantly.

Natural Language Processing (NLP)

Take advantage of tokenizing and lemmatization while indexing, allowing you to search plurals or lemma of keywords effectively. For instance, search for "hike" and also receive results for "hiking," or search for "children" and find results for "child."

In-built Scanner

PDF Search comes equipped with a scanner tool, enabling you to scan documents, notes, or cards into PDFs. Enjoy searchable text within scanned documents, thanks to the OCR feature.

Text Recognition in Images within Documents (OCR*)
Leverage our built-in OCR capabilities, allowing you to index and search text on images inside documents for supported languages.*

Unified Search Experience

Seamlessly search documents on your Mac using your iPhone or iPad. Sync your files over WiFi with a single click and take your documents wherever you go.

*NOTE: The OCR feature requires iOS 13 or above. Supported languages include:

iOS 13: English
Subsequent iOS versions: English, French, German, Italian, Spanish, Portuguese, Chinese

### 2/5 — Constantly crashes

*2026-05-17, version 8.31*

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.

### 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, version 8.31*

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, version 8.27*

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.

### 3/5 — Needs keyboard support

*2024-04-23, version 8.27*

Cmd + F for search (with Esc to cancel search), shortcuts for navigating through document / to other documents, etc.
