A Markdown File Should Just Open

You can do this on KDE. Just set Okular as the default app for markdown files. The only problem is that it is a viewer not an editor. There are editors with preview which solve that. Even editors without preview will highlight, and, there is already software that provides exactly what the author wants (notepad, which the article mentions) or visual editing of markdown (Libre Office)

I am not sure its that important that its a default. Markdown is primarily and editable format that is easily converted to a readable one - its the inverse of PDF which is a readable format that is hard to edit.

While I do agree with the author's overall point, I think that he inadvertently stumbles on the probable reason here:

> If I want to see the original Markdown syntax, I should be able to switch to that view just as easily.

This doesn't really map well to existing document opening conventions, so the author's hypothetical built-in Markdown viewer/editor doesn't really fit into any existing system app. For example, if Apple modified TextEdit.app to open Markdown files in the same way it handles RTF documents, it would cover the formatted display case, but not editing the source. They would have to add some third mode (or build an entirely separate app) to handle switching between Markdown source and formatted views, deal with displaying malformed syntax, etc. Not to mention handling the various differences between Markdown flavors.

This essay could have been a prompt. I have a markdown viewer. Comes out of the same codebase as my json viewer https://wiki.roshangeorge.dev/w/Blog/2026-04-30/Personal_Sof...

I felt the same but if you put it into Claude code Opus 5.5 can build you a program that will open faster than anything you’ve ever used before if you ask for it. I asked for it and it’s instantaneous. Faster than literally any other macOS app.

It opens and displays a markdown file faster than bitwarden’s chrome extension displays its fill UI.

The future is almost here. Formats and so on are on the threshold of irrelevance in the next few years for this kind of consumer use. It’s hard to even tell if the time it takes us to summarize a text will be the time a future agent takes to write a specialized program that extracts what you need from the file. “Native” support will soon be irrelevant.

Even my solution is yesterday’s solution.

This is probably getting into old man yells at cloud territory, but it's markdown... Open it in a text editor. That is the most of point of having markdown, nice looking plain text. typeset text is the side effect, if the point were typeset text I would hope that a better format than markdown was used.

I was searching for a simple markdown viewer for Ubuntu.

Shockingly, I could only find about 3, and all sucked in their own special way.

I have the simplest of requirements: just format it and show it like a PDF. Either the app doesn't remember its position and always restarts in an awkward landscape format, or it insists in showing a "file tree" side bar, no simple file viewer.
