Celdario is a viewer and editor for Jupyter notebooks on macOS. It opens .ipynb files instantly,
renders every common output type offline, searches and replaces across the whole notebook,
edits cells in place, exports to HTML, PDF, Markdown and script, and previews notebooks in
Finder with Quick Look. It has no kernel, no network access and no telemetry. Celdario is made
by Virgee LLC and sold on the Mac App Store.
