Coggle vs Zim

Markdown is a plain text formatting syntax designed so that it can optionally be converted to HTML using a tool by the same name.

Coggle allows inviting friends and colleagues to work collaboratively on notes and diagrams in real-time.

No effort to create beautiful diagrams.

LaTeX is a document preparation system and document markup language. It is the de facto standard for the communication and publication of scientific documents.

Enter history mode to view all changes to a diagram over time, and make a copy from that point.

Exports to PDF, image, plaintext and .mm files.

Notes can contain links to other notes, allowing you to reference important information when needed. This way the user can connect and reference many different pages in the app, keeping things clean and structured, unlike Evernote, which makes this a good Evernote alternative.

If/when the app is no longer developed (or if the user simply decides to no longer use the application or view/edit it on a non-supported platform), this can still be done with any plain-text editor.

Zim will automatically create a folder structure that fits your page hierarchy and adds/removes files such as images to/from appropriate folders.

Zim supports HTML, LaTeX, Pandoc Markdown, and RST. This allows ones documents to be easily used in a wide selection of other apps.

Windows, Linux, and BSD are supported with their own clients. This is nice for those that use multiple operating systems but still want to use the same app on each.
