*Markdown syntax shows up only on the line you're editing, then dissolves into rendered formatting.*

> A free, open-source markdown editor that renders syntax inline as you type — no preview pane, no WYSIWYG mode, no split screen. Asterisks and hashes vanish into formatting on lines you've left, and reappear when you cursor back in.

Headings get larger and bolder as you write them; lists indent into bullets the moment you hit space after a dash; links collapse to their visible text and expand when clicked. The mental cost of switching between "writing" and "previewing" never comes up because both happen in the same view.

Electron-based — about 200 MB on disk and modestly heavy on memory — but the editor itself is responsive and the codebase is small enough to fork. MIT license.
