I was not sure. So I tried the trial.
I posted one of my Medium articles to Hashnode.
It actually did post the article.
It's not a perfect and polished UI but did the job.
Here is the article posted using crossxpost.app

I did not do any edits which were possible in the tool. It has a text editor there.
It copies the Medium blog as HTML to Hashnode and the code is not clean. It is hard to edit. Overall not the best solution.
I would prefer to use MD as the source and publish across.
