Joplin is a free, open source note taking and to-do application, which can handle a large number of notes organised into notebooks. The notes are searchable, can be copied, tagged and modified either from the applications directly or from your own text editor. The notes are in Markdown format.

Notes exported from Evernote via .enex files can be imported into Joplin, including the formatted content (which is converted to Markdown), resources (images, attachments, etc.) and complete metadata (geolocation, updated time, created time, etc.). Plain Markdown files can also be imported.

The notes can be synchronised with various targets including the file system (for example with a network directory) or with Microsoft OneDrive. When synchronising the notes, notebooks, tags and other metadata are saved to plain text files which can be easily inspected, backed up and moved around.

The notes can be securely synchronised using end-to-end encryption with various cloud services including Nextcloud, Dropbox, OneDrive, WebDAV or the file system (for example with a network directory). When synchronising the notes, notebooks, tags and other metadata are saved to plain text files which can be easily inspected, backed up and moved around.

Full text search is available on all platforms to quickly find the information you need. The app can be customised using plugins and themes, and you can also easily create your own.

The application is available for Windows, Linux, macOS, Android and iOS. A Web Clipper, to save web pages and screenshots from your browser, is also available for Firefox and Chrome.
