Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

3.0

GPA, above 107 of the 147 other note-taking apps we grade

Zim is an open-source desktop wiki: a graphical text editor for a collection of linked pages kept on your own computer. Pages sit in a folder structure like an outliner, can have attachments, and are saved as plain text files with wiki formatting that other editors can read. Plugins add a task list, an equation editor, calendar pages for journals and version control.

To get you started, here are 8 things to know about Zim, taken from its own pages and our grades.

It's written for one person, has no phone or web app and no sync of its own, and notebooks have no password or encryption.
From our report card of Zim
  1. 1

    Best for a personal wiki kept as text files on your computer

    Zim is a free, open-source desktop wiki where every page is a plain text file in a folder on your disk and links are tracked both ways.

  2. 2

    It is free

    Zim has no paid plan at all. Open-source software under the GPL 2.0 license. The download page offers the source, a Windows installer, a macOS app and Linux packages, and lists no paid edition.

  3. 3

    It runs on 3 platforms

    Windows, macOS and Linux.

  4. 4

    Plain-text wiki pages

    Every page is a text file with wiki markup and images are ordinary linked files, so the content stays readable in other editors and file managers.

  5. 5

    Links in both directions

    Linking to a page that does not exist creates it. Zim tracks all links and shows, for each page, which other pages link to it.

  6. 6

    Hierarchical notebooks

    Pages nest as sub-pages in a folder structure, much like an outliner, and each page can carry attachments.

  7. 7

    A 3.0 GPA, above 107 of 147

    That is against the other note-taking apps we grade, on value, the free plan, features, ease of use and platforms.

  8. 8

    Keep it

    Zim is free, so making your own would save you nothing.

The report card

Best for a personal wiki kept as text files on your computer

Zim is a free, open-source desktop wiki where every page is a plain text file in a folder on your disk and links are tracked both ways. It's written for one person, has no phone or web app and no sync of its own, and notebooks have no password or encryption. The Windows build is 64-bit only, and the Mac app covers Big Sur through Sequoia.

ToolGPA report cardZimGraded Oct 10, 2026
SubjectGradeComment
Value for moneyAIt's free. Zim is open source under the GPL 2.0 and its download page lists no paid edition, in a category where the middle plan wants $6 a month.
Free plan and trialAThe whole desktop wiki is free on Linux, Windows and macOS, plugins included. There's no paid tier, so nothing is held back.
FeaturesCAs a wiki it's all there: pages nesting like an outline, links tracked both ways, attachments, HTML export, and plugins for a task list, an equation editor and calendar pages. Its own FAQ names the holes, though. No encryption or password on a notebook, no sync but copying the folder, and one person at a time.
Ease of useBNo rating on record, but there's nothing to set up: an installer for Windows, an app for macOS, packages in most Linux distributions. Link to a page that doesn't exist and Zim makes it for you.
Platforms and integrationsCComputers only: Windows, macOS and Linux, with no phone or web version. The version control plugin talks to Git, Mercurial or Bazaar, but syncing is you copying the notebook folder with something like Dropbox.
Grade point averageVery good, out of 4.03.0

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who Zim is for

  • Fits if you want a private wiki or scratch book as plain files on your own disk
  • Works for a daily journal with a page per date, kept under Git if you like

Who it is not for

  • Skip it if you want your notes on your phone or the web, because it's desktop only
  • Not for you if your notes need a password, as there's no encryption; the FAQ points to an outside tool
  • Too light for a team writing together, since it's single-user and merging goes through version control
  • Tight if you want sync, which means copying the notebook folder with something like Dropbox
  • Watch out: the Windows installer is 64-bit only, and the Mac app supports Big Sur through Sequoia

Good to know

Good for

  • A personal wiki or scratch book kept as files on your own disk
  • Daily or weekly journals and meeting or lecture notes
  • People who want their notes under Git or another version control system

Worth knowing

  • Notebooks have no built-in encryption or password protection; the FAQ points to an outside tool such as encfs.
  • Zim is written as a single-user program, so shared notebooks rely on a version control system to merge changes.
  • The download page covers Linux, BSD, Windows and macOS only, and syncing means copying the notebook folder with a service such as Dropbox.
  • The Windows installer supports 64-bit systems only, and the macOS app supports macOS Big Sur through Sequoia.

Part 04 · Standing

Where it stands

Its grades against its category, and whether to keep it or make your own

107/147

Other note-taking apps it is graded above

Zim's GPA of 3.0 is higher than 107 of the 147 other note-taking apps we grade, and level with 21.

It stands best on free plan and trial (A, above 100 of 147) and worst on features (C, above 2).

Zim has no paid plan.

On features, ease of use and platforms it scores 2.3 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price.

Each grade against the category

Every bar is all 148 note-taking apps we grade, cut by the letter each got. Zim’s own letter is outlined.

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

Zim is free, so making your own would save you nothing.

It is one of the better ones too: its GPA of 3.0 is higher than 107 of the 147 other note-taking apps we grade.

What you could make

  • Notes, wiki, linked notes, daily notes and tasks: an app builder makes these well.

What you could not

  • Apps for macOS, Windows and Linux that stay in step with each other.

What this rests on. Zim’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
