This is a live demo. Click any line to move the caret: Markdown markers appear only where you are editing. Try Preview, Focus and the Aa panel.

Your notes stay plain .md files in the folders you already have. No import, no database, no lock-in.

Features

Everything renders as you type.

Headings, bold, italic, strikethrough, highlights, links, inline code, code blocks, quotes, tables, math and task lists. The syntax gets out of the way until you need it.

Point it at any folder and it edits your notes in place.

Git sync from the sidebar

A button shows the branch and pending changes. One click commits, pulls (rebase) and pushes, or initializes a new repository.

Sam raised that people keep notes inside code repositories, which means Sync currently commits unrelated changes.

Sync should add and commit only the paths inside the notes folder, and the change count should only count those paths.

Priya showed the new settings window. Feedback was positive; the privacy tab in particular reads well.

Focus on paragraph

Everything but the paragraph you're in dims. Typewriter scrolling keeps the line you're writing centred. Hover the text to try it.

Open source

Calm by design.

Native, not Electron.

Built with SwiftUI and AppKit (TextKit) and Apple's Liquid Glass. Typing stays fast on long notes thanks to incremental highlighting.

No accounts, analytics or tracking.

Turn off the preview's CDN scripts and remote images; both are enforced with a Content-Security-Policy. Update checks are off until you agree to them.
