Vim on desktop using instant markdown plugin to have a preview in a browser tab. It fits my needs. The only thing I would like is markdown to be native in confluence to share my technical documents in markdown at work. Currently, there is only an insert markdown function, but it lacks all the commenting. ~~It also lacks mermaid support which is a blessing for schemas~~ (it seems it was added recently, I'm blessed).

I've been using ghostwriter for a while now (with the preview tab disabled). It's very lightweight and distraction-free, but has some unusual bugs. I've also been attempting to use pandoc to make some nice PDFs recently, but haven't found a good setup yet.

I use vscode to preview and edit md files. Recently, I was working on a project where I used pandoc to generate a pdf of all the markdown files in folder. Worked pretty well, but it took me a minute to configure it right.

Mainly just markor on android, and vim/helix on desktop. I'd really love to have a wysiwyg client on android like typora, but one doesn't exist yet.
