MarkChart - Mermaid Editor

I tried a different, cheaper app, and it was useless. This app, with its $9 price tag for pro (so you can export PDFs) is well worth it — a bargain, really, because it saved me so much time. The app is easy to use, with a clean and clear user interface, and plenty of templates and custom capabilities. Recommended.

I use MarkChart erDiagrams for Xcode Schema documentation for my projects. I make markdown files in my project and use the open in external editor to launch MarkChart as the editor. Great tool. Especially when using AI Assistant to generate the erDiagram text from my model files.

The application works well and I have been using is daily, but good luck if you get into a syntax error. Some even minimal help with debug would make this a 5+ star app.

Works fine, except an aspect of the editor. When there is a syntax error it stops at the first one, you fix it, it finds the next. Better to loop through the entire Mermaid code find the errors, propose a solution with an approve button.

Ntshaykolo

From downloading it, it took about 5 minutes to understand the UI, get a sequence diagram rendering, and exported to a PNG. Excellent. (My only little nit is that I wish it watched the underlying markdown file, so that it noticed changes produced when I modify it with another editor.)

png images should have a transparent background

This is quite good... however, I can't seem to change my background color to white. If I use the base theme and set the background color, the setting is ignored. I'd also like the ability to set a zoom factor when exporting images. Other than that, I have absolutely no complaints. It works as advertised, is fast, and seems to be stable. Fixing those two issues will each earn back a star in the review!

Really helps when writing markdown documents. Can review sequence diagrams interactively

A simple but powerful too
