Features & Capabilities

MarkChart is designed exclusively for previewing and editing Mermaid diagrams. Start with a built-in template to instantly create sequence diagrams, state diagrams, flowcharts, and more. Or begin with a blank document to write your own diagram from scratch.

Mermaid is a Markdown-inspired text syntax to define diagrams. MarkChart will render a nice looking sequence diagram if you write the following text in your Markdown documentation:

sequenceDiagram
    Alice->>John: Hello John, how are you?
    John-->>Alice: Great!
    Alice-)John: See you later!

PREVIEW Effortlessly previewing Mermaid diagrams without complex tools.

EDITOR Create and edit your Mermaid diagrams directly in MarkChart.

This tool works great and would be perfect with just some UX tweaks to allow zooming and dragging when using a mouse.

As far as I can tell it allows you to edit the Mermaid text in one pane, and see the results in another. Not any different from editing the mermaid text in your favorite editor and then firing up a viewer in another window.

This is exactly the kind of tool I was looking for that allows me to write diagrams with my text editor of choice with all its features and shortcuts that I'm used to, and see the diagram rendered immediately on saving the file. It also has some nice export options for the rendered diagrams. Overall, worth the 9 bucks for the full version. My only issue so far is that it does not specify anywhere what version of the Mermaid standard it supports. The help and FAQ link to the official Mermaid site for reference on Mermaid syntax which implies it should support everything documented there, but I have noticed it doesn't support newer features such as central connections and half arrows on sequence diagrams, and it also does not support combining aliases with participant type configuration on sequence diagrams either. It would be useful if the Mermaid version the app supports was listed somewhere (such as the FAQ or Release Notes), to make it clear what features should be expected to be supported.
