Zim

What Zim is

Zim is a free desktop text editor for maintaining a personal collection of linked wiki pages, with offline access on Linux, macOS, and Windows. It saves pages automatically as plain text files using wiki formatting, while images remain separate linked files. Pages can be arranged hierarchically, and backlinks show which other pages refer to a page. Zim reopens at the location where it was closed. Included plugins provide tools such as spell checking, equations, task lists, full-text search, a tray icon, and version control support. Notebooks can be exported to HTML, LaTeX, Markdown, and reStructuredText. The project describes uses ranging from personal notes and TODO lists to journals, meeting notes, brainstorming, and longer drafts. It integrates with Git, Mercurial, and Bazaar. Zim is designed for one user rather than shared notebook editing, and notebooks lack native encryption and password protection. The listed Windows installer supports 64-bit Windows 11; the macOS app supports Big Sur through Sequoia.
