A focused workflow
Use document tools
Pro adds AI assistance, local OCR, content editing, merge and split, redaction and conversion tools.
Review the source
Follow page references and approve proposed highlights or notes before the PDF changes.
Before you start
Check AI answers against the document. Scans need OCR for text-based search and AI. On-device AI depends on system support; optional Cloud AI sends document text after consent. Complex converted layouts may need adjustment.
Access & data
AI, OCR and advanced editing/export tools require Pro. Editing, conversion and OCR run locally; cloud AI is optional.
