Pdf Text Search is an app to search for text in a pdf document. Select a pdf document to import, and the app reads the text in that document and converts it into searchable text entries. As you input your search, the app finds the entries that include your search. You can search for only the exact text you enter or for one or more words you enter (in any order). You can then click on the relevant entry and see full text for that entry and click that text to see the pdf page where that entry is located. You can also save and share entries. When you import a document, the app saves that document. You can view saved documents in a list or in augmented reality.

The app also saves your searches, so you can re-use them by clicking the magnifying glass in the search bar.

The app also includes an optional annual auto-renewable subscription (Pro) that begins with a free two week trial period. Upgrading to pro enhances the functionality of the app. When using the base version of the app, you can save up to three entries and documents. Upgrading to pro allows you to save additional entries and documents.

In addition, upgrading to pro allows you to select two or more pdf documents and the app will use an algorith referred to as TF-IDF (term frequency - inverse document frequency) to identify terms based on their frequency in the document compared to their frequency in the other selected documents. After the app has processed your selected documents, you can click on a document to view the top terms based on their TF-IDF score and then you can click on one of those terms, load the document and search for the selected term in that document. This feature is available in the base version of the app until July 2022.

A subscription purchase will be applied to your Apple account at the end of the trial period. Subscriptions will automatically renew unless canceled within 24-hours before the end of the current period.
