It reads pages the way you would.
PDF Search scores every page by how close your keywords are, how often they appear, and whether they sit in a title or in bold. The best pages come first, from every document at once.
AI Chat with your documents
Ask a question and get an answer with the pages it came from. Summarize a chapter, compare two reports, or get study help without opening a single file.
Relevance ranking, instantly
Keyword distance, density and emphasis all count. Jump between the best pages of different documents without waiting.
Built-in OCR
Text inside screenshots, photos, scans and handwritten notes becomes searchable, right on your device.
Linguistic search
Search “work with mouse” and also find “work with mice”. Plurals and word roots are understood, powered by Apple’s Natural Language framework.
Summarized PDF export
Turn the relevant pages from hundreds of documents into one short PDF you can share with your team.
Beyond PDF
Word, PowerPoint, Pages, Keynote, RTF, plain text and source code, with no other apps required.
Mac to iPhone sync
Send thousands of files and the ready-made index to your iPhone or iPad over Wi-Fi or cable. No re-indexing.
Private by default
Indexing, OCR and search never leave your device. Only the text you choose to discuss is sent to the AI.
