nibspark

nibspark is a Markdown editor made for writing, not fiddling. Your
docs are plain Markdown files that open anywhere and are always yours.
In the editor, the syntax stays on screen but fades into the
background, so the words come first. Beside it, a live preview shows
the finished page as you type, with tables, images, callouts and
diagrams drawn the way they'll be read.

Almost everything is a keystroke away. Type / to add a heading, a
table or a diagram, open the command palette for any action, and
jump between docs without reaching for the mouse. nibspark saves as
you go, so you can stay in the flow until the last word.
