Joplin is an open-source note taking and todo application that can manage a large number notes in a notebook. You can search the notes and copy, tag, and modify them from either the application or your own text editor. The notes are in Markdown format. Joplin can import Evernote notes via.enex files. This includes the formatted content (which has been converted to Markdown), resources (images and attachments, etc.). Complete metadata (geolocation and updated time, created times, etc.) Plain Markdown files are also possible to be imported. The notes can be synchronized using various cloud services such as Nextcloud, Dropbox and OneDrive. Notes, tags, and other metadata can be synchronized with cloud services such as Nextcloud, Dropbox, OneDrive, WebDAV, and File System (for example, with a network directory). Plain text files can be easily inspected, backed-up, and moved around. The application is available on Windows, Linux, macOS and Android.
