Skein is a native Mac note-taking app for working with plain Markdown files, tags, links, graph views, and canvas boards in a local folder.
What is Skein?
Skein is a native Mac note-taking and knowledge management app built around plain Markdown files stored in a folder you choose. It is designed for people who want a local-first notes workflow without locking their writing into a proprietary database or service. On macOS, Skein lets you browse, search, edit, and organize notes directly from a Markdown vault, making it useful for personal knowledge bases, project notes, research collections, and everyday capture. The app supports familiar Markdown structures, tags, links, and canvas boards, and it can work with note folders you already use in other editors. Skein also includes tools for quick capture, note history, and navigation across linked notes, which helps users who prefer a lightweight desktop writing environment centered on ordinary files.
Key features
- Create and edit notes stored as plain Markdown files in a folder you choose
- Search note titles and full note contents from one workspace
- Organize notes with tags, folders, and linked references
- Open and work with JSON Canvas boards alongside notes
- Use quick capture to save ideas without creating manual file names first
- Browse connections between notes with linked navigation and graph-based views

Safety overview
Status: Safe
Skein uses files in the note folder you choose, so it can read and update the notes stored there as part of its normal purpose. That access is expected for a local Markdown notes app. If you keep sensitive notes, store them in a folder you control and maintain your own backups before making large edits or reorganizing files.
Recommendation: Keep Skein if you use it for Markdown notes or a local knowledge base on your Mac. Remove it only if you no longer use the app, and remember that uninstalling the app does not necessarily remove the note files you created or selected for it.
