Openview

Openview is a native macOS PDF reader you can talk to. It feels like Apple Preview — the same fast native scrolling, find, and highlighting — but you can ask questions about the document and get answers pulled straight from its text. What makes it different: the AI runs entirely on your Mac with Apple's on-device foundation model (Apple Intelligence). No API keys, no cloud, no subscription, nothing leaves your device. And because it's truly native (AppKit + PDFKit), it's fast and lightweight.
