Opening PDFs vs. Using AI Summarization Features

Adobe Acrobat Reader Mobile allows users to open, view, and read downloaded PDF files entirely for free. These basic functionalities do not require a paid plan.

The Acrobat AI Assistant is an optional, premium add-on entitlement. You only need an active AI subscription when you want to utilize generative AI tools, such as automatically summarizing a document or chatting with the PDF content.
