A calm place to just write.
Write and preview markdown side by side — live rendering, a serif reading column, an outline, diagrams, and export. No clutter, just your words.
Everything you need, nothing you don't
Built for focused writing on macOS.
Live split preview
Type on the left, watch it render on the right — in a serif reading column that looks like a printed page. Resizable.
Ink-on-paper themes
A warm light mode and a cozy dark mode. Easy on the eyes, day or night.
Outline & search
Jump around with an auto-generated outline, and find anything in your document instantly.
Diagrams & code
Mermaid diagrams and syntax-highlighted code blocks render right inside your notes.
Smart paste
Paste a link onto selected text to make it a link; paste an image and it's saved beside your file.
Export anywhere
Send your writing to PDF or HTML, or copy it as rich text — formatting intact.
Light or dark, your call
Toggle with a keystroke; it remembers your choice.
Start writing
Free for macOS. Signed and notarized by Apple — opens with no warnings.
