NorktavisionA document reader for Mac, iPad and iPhone
Keep the whole
idea in view.
One window.
A little more perspective.
A wider view
The paper. The reference.
The connection between them.
Read a paper beside its reference. Keep a tutorial next to your notes. Norktavision brings PDFs and local HTML into the same native Mac workspace, with a place for each document.
Stay with the page
Less searching.
More reading.
Move through individual page previews or a document’s outline. Find a phrase, adjust the zoom, and keep the controls close without filling the screen with them.
- Thumbnails and document outlines
- Single page, two-page, and continuous reading
- Per-document zoom, inversion, and warm tone
A place to return
Pick up
the thread.
Continue Reading brings you back to where you left off. Import PDFs into Library to keep app-owned copies, or open a document directly from where it already lives.
- Reading positions remembered
- Recent items you can dismiss individually
- Local PDF copies, with originals left untouched
At home on every screen.
Native
A workspace, not a browser tab.
Tabs and resizable panes on Mac and iPad, keyboard commands and multiple windows on Mac. Built with native Apple document viewers.
Flexible
Beyond the PDF.
Read local HTML too, including self-contained Quarto, R Markdown, and Jupyter exports, alongside your PDFs.
Local
No reader account needed.
Your library and reading history are stored on your device. Norktavision doesn’t require an account.
A closer look

Make room
for the next idea.
Requires macOS 26, iPadOS 26 or iOS 26 or later.
What can I open?
PDF files and local HTML, HTM, or XHTML documents. Library import currently stores PDF copies; HTML opens from its existing location.
Can I read several documents together?
Yes. On Mac and iPad, a tab holds up to four documents in resizable panes when there is room; on Mac you choose from eight layouts. Every pane has its own document, reading position, zoom, and navigator. On iPhone, documents open in tabs.
