FSNotes

FSNotes is a native notes manager for macOS and iOS that stores each note as a plain file on the local file system. It works with open formats such as GitHub‑Flavored Markdown and TextBundle containers, allowing text and images to be kept together. The app supports iCloud Drive sync, so the same files are available across devices, and it can encrypt TextBundle containers with AES‑256 for sensitive content.

The interface is keyboard‑centric and includes TouchBar buttons on supported Macs, dark mode, and a two‑pane elastic view. It offers features like tag organization, cross‑note links using double brackets, syntax‑highlighted code blocks for many programming languages, Mermaid and MathJax rendering, and optional Git versioning for backups. Users can pin important notes, copy them quickly, and edit with external editors while changes sync live.

FSNotes is open source and stable, targeting users who prefer a fast, lightweight, Markdown‑first workflow without subscription fees. It emphasizes local file ownership, iCloud synchronization, and optional encryption, making it suitable for developers, writers, and anyone needing a straightforward, file‑system‑based note‑taking solution.
