Binderus
What it is
Binderus is a local-first note-taking app for Linux, macOS, and Windows that edits plain Markdown files in a WYSIWYG editor. The editor supports slash commands, tables, code blocks, LaTeX mathematics, and Mermaid diagrams. Notes can be organized with multiple vaults, instant search, plugins, themes, wikilinks, and backlinks. Users may keep notes as ordinary Markdown files or choose an encrypted local database. That database uses AES-256 encryption and derives its key with Argon2id; Binderus says a forgotten passphrase cannot be recovered. Images and attachments stay unencrypted on disk unless attachment encryption is enabled. Binderus has no proprietary sync server, while its documentation describes syncing through iCloud Drive, Dropbox, OneDrive, Google Drive, Syncthing, or Git. Vaults must be inside the operating system’s Documents directory. Markdown files remain portable, and exports include PDF, DOCX, and HTML. The desktop app is free forever with no account required.
