Joplin is a versatile, open-source application designed for note-taking and task management, capable of accommodating a substantial volume of notes that are systematically arranged within notebooks. Users can search for, copy, tag, and edit these notes directly through the app or using their preferred text editor, with all notes formatted in Markdown. Additionally, it supports the import of Evernote notes through .enex files, allowing for the preservation of formatted content (which gets converted to Markdown), along with resources like images and attachments, as well as comprehensive metadata such as geolocation and timestamps. Furthermore, plain Markdown files are also compatible for importation. The app offers synchronization with various cloud storage services, including Nextcloud, Dropbox, OneDrive, and WebDAV, as well as local file systems such as network directories. During synchronization, all notes, notebooks, tags, and associated metadata are stored in plain text files, which allows for straightforward inspection, backup, and transfer. Joplin is accessible on multiple platforms, including Windows, Linux, macOS, Android, and iOS, ensuring broad usability for diverse users. Overall, its flexibility and feature-rich environment make it an excellent choice for anyone seeking a robust note-taking solution.
