Native PDF viewing

PDFKit-backed continuous scroll, find, and zoom — plus highlight / underline markup saved straight into the PDF.

On-device AI Q&A

Ask about the open document and get answers drawn from its text — retrieval plus Apple's on-device model.

Private by design

No account, no cloud. Your document and your questions never leave your Mac.

Read it. Ask it. Keep it on your Mac.

Openview pairs a Preview-grade reader with an on-device assistant grounded in the page in front of you — no servers, no sign-in.
