Kerned, the Markdown Editor That Leaves Your Files Alone

Field notes

Kerned is presented as a local macOS editor for existing Markdown files rather than a note database or synchronized workspace. Its central constraint is byte-level conservatism: the page says line endings, trailing whitespace, ragged table padding, and odd escapes survive a save, while external changes from Git or scripts appear in the editor. The listed build is 0.1.1 for Apple Silicon and macOS 13 or later, and the project explicitly solicits reports of files it mangles.
