A: 1) Here's my use case. I am using Divi builder to write my articles and everytime I copy paste my content from Google doc to builder, it messes up formatting. I have to manually add H1, H2, pics, etc, again. TAKES LOT OF TIME. Does Swish solve this?

The editor in Swish handles pasting from most sources correctly. I personally know of users who prefer to write on Google docs and paste into Swish. You can try one of your articles on https://demo.swish.ink and check if it handles it correctly.

>>> 2) Do you have a plugin for WordPress

Swish has a WordPress integration to import posts. It can also cross post from Swish to WordPress. This would not be a plugin on WordPress, but an integration setup on the Swish blog.
