Ask HN: Looking for a Show HN about a Document Editor

I should have bookmarked it.

Need help finding a post from no earlier than two years ago. I believe it had a mildly esoteric or abstract title.

It was showcasing a document editor that combined elements of markdown, latex, html/css. I believe it was intended for web page creation.

Seemed like a modern, feature rich markdown.

It had a strong sense of style and minimalism, but I can't remember the name. I know this is not much to go off of, but maybe someone knows.

Other detail I can remember is that I believe it was installed via NPM.

And yes, I have scoured the search for Show HN posts with "text", "document" and "markdown" to no avail.
