Jupyter Notebook Viewer
Jupyter Notebook Viewer is a native macOS app for opening and reading Jupyter and IPython notebook files without launching Jupyter.
What is Jupyter Notebook Viewer?
Jupyter Notebook Viewer is a native desktop app for macOS that helps users open and read Jupyter and IPython notebook files in a lightweight local viewer. It is designed for developers, students, researchers, and anyone who receives .ipynb notebooks but does not want to start a full Jupyter environment just to inspect the contents. The app focuses on viewing notebook structure and rendered content, including code cells, formatted Markdown, equations, and saved outputs. It also includes Finder Quick Look integration, which makes it convenient to preview notebooks directly from the file browser. Jupyter Notebook Viewer is useful for reviewing shared notebooks, checking reports, and reading notebook-based documentation on a Mac. It is published by Tinowagner.

Safety overview
Status: Mostly safe
This app is intended for local viewing of notebook files and its file access is consistent with that purpose. Opening notebooks can expose whatever content is stored inside them, including code, text, images, or saved outputs, so use files from trusted sources when reviewing sensitive material. Removing the app simply takes away its notebook-viewing and Quick Look functionality.
Recommendation: Keep Jupyter Notebook Viewer if you regularly read .ipynb files on your Mac or want Quick Look previews in Finder. If you no longer use Jupyter notebooks, you can remove it without affecting macOS beyond losing that viewing convenience.
