Zettel Notes : Markdown App

Zettel Notes is a free, private markdown note-taking app built around the Zettelkasten method, enabling efficient knowledge management without vendor lock-in. It stores notes as separate markdown files, supporting offline use and optional synchronization via Dropbox, Git, WebDAV, and SFTP.

Key features include app lock, bookmarks, calendar view, full-text search, LaTeX support, multiple vaults, encryption with PGP keys or passwords, a plugin system, and templates. The app handles various note types such as task, audio, and bookmark notes, and supports multi-language interfaces. Users can import existing notes easily by adding repositories or folders, share notes as PDFs or HTML, and organize notes with sorting and subfolders. Zettel Notes emphasizes privacy with no data collection beyond crash reports, a clean ad-free experience, and extensive customization options via themes and fonts.
