how it works

one loop. nothing leaves your machine.

open a folder of markdown notes. that's your context library.

edit side-by-side with live preview. save when ready.

copy clean markdown to clipboard. paste into claude.

features

drag files between folders. right-click for rename, new file, new folder. ⌘⌥Z to undo. your context library, organized like a project.

edit on the left, watch markdown render on the right. mermaid + math + shiki, all live.

press ⌘. for a calm, preview-only view with generous typography. perfect for proofing before you paste.

press ⌘⇧C to copy the current file as clean markdown. paste into claude, chatgpt, gemini, your local agent — anywhere that reads text.

⌘F find/replace, ⌘⌥Z undo file ops, ⌘K command palette grouped by category. it's all there. 5 themes too — catppuccin + matcha.

your notes never leave your machine. no telemetry, no cloud, no account. just files.
