Good, not great.

Amazing, does the job but doesn't feel as polished as it should be.

Promises visual editing, but not in the app

I downloaded this app specifically to edit Mermaid diagrams visually. In the app store is says you can do that. On their web page it says “Edit visually With the interactive canvas.” But I don’t see anyway to do that.

Google says:

MarkChart and standard Mermaid tools are diagram-as-code systems. They generate layouts automatically from text, meaning you cannot freely drag and drop or manually move shapes around on the preview screen

So, which is it? If you can’t then it’s pretty blatant false-advertising.

Response from developer

Thank you for your feedback! To clarify, MarkChart does include a visual editor, but it currently focuses on visually customizing diagram elements rather than freely repositioning them. You can click nodes and connections directly in the diagram to change their shape, fill color, border color, text color, and text size. The diagram layout itself is generated automatically, so nodes cannot currently be freely dragged and dropped or manually positioned. – Alex

Very good

Amazing

Kaputt

Wenn man die App startet wird man in eine andere Umgebung weiter geleitet. Dort kann man zwar Vorlagen betrachten, diese aber nicht bearbeiten. Nicht überzeugt.

Response from developer

Vielen Dank, dass Sie sich die Zeit für Ihr Feedback genommen haben. Es tut uns leid, dass die App nicht Ihren Erwartungen entsprochen hat. Beim Start zeigt die App zunächst eine Galerie mit Beispielen, um den Einstieg zu erleichtern. Diese Vorlagen dienen nur zur Ansicht. Eigene Diagramme können Sie erstellen, indem Sie ein neues Dokument anlegen oder ein bestehendes öffnen. Falls Sie auf ein anderes Problem gestoßen sind, freuen wir uns über eine Nachricht an support@markchart.app, damit wir Ihnen weiterhelfen können. – Alex

真的是良心软件，¥38该有的全有

Obsidian的问题是手机版本太慢，这个打开挺快的，渲染也很快，随时编辑，mermaid语法。试了好几个类似软件就这一个好用的。而且还支持macOS！！！iPad iPhone三端同步，不说了，再说像个吹子了。
