What Binderus is

Binderus is a free desktop note-taking app for Linux, macOS, and Windows that works with plain Markdown files. Its WYSIWYG editor includes slash commands, tables, code blocks, LaTeX math, and Mermaid diagrams. Notes can be organized in multiple vaults, searched instantly, and linked with wikilinks and backlinks; plugins and themes are also supported. Users can keep notes as ordinary files or choose an encrypted local database. That database uses AES-256 and derives its key from a passphrase with Argon2id; Binderus says a lost passphrase cannot be recovered. Images and attachments remain unencrypted on disk unless attachment encryption is enabled. There is no proprietary sync server, but the documentation describes syncing through iCloud Drive, Dropbox, OneDrive, Google Drive, Syncthing, or Git. Vaults must be inside the operating system’s Documents directory for Binderus to read and write them. Markdown notes can be opened in other editors or exported to PDF, DOCX, and HTML. The full app is free forever, with no account required.
