Hybrid WYSIWYG

**Markers hide** until your cursor touches them, then reveal in place. Headings, lists, quotes, links, checkboxes — styled live, raw on demand.

Live tables & images

Tables render as real tables and images render inline while you edit. Touch one and it dissolves back to source.

78 languages

Tree-sitter highlighting in fenced blocks and standalone files. Code files get a real editor: gutter, auto-indent, monospace, full width.

Your theme

Six built-in themes with a live ⌘T picker — or drop your own TOML in ~/.supermd/themes. Light and dark follow the system.

Never lose a word

Autosave with atomic writes, per-session backups, and external-change detection that never silently clobbers anything.

Native & fast

Rust on GPUI — the GPU-accelerated framework behind Zed. Instant startup, 120 fps scrolling, a ~15 MB download.

Plain files, forever.

No database, no lock-in, no export step. SuperMD edits the Markdown files already in your folders — and they stay exactly that.
