Zettlr as a Linux alternative to Microsoft OneNote
Updated
Our verdict
Zettlr can replace Microsoft OneNote for users who prefer Markdown and file‑based workflows, especially researchers and writers who need citation integration and Zettelkasten linking. It is not a drop‑in replacement for casual note‑taking with rich media or tight cloud sync.
