Joplin is a free, open-source note-taking application that works on Windows, macOS, Linux, Android, and iOS. It focuses on privacy and portability: notes are stored in Markdown format (a plain text format that supports simple formatting like headers, bold text, and lists), and syncing happens through cloud services you already use or control, including Nextcloud, Dropbox, OneDrive, or any WebDAV-compatible storage. Because the sync files are plain text, you can inspect, back up, or move your notes without being tied to any proprietary format. Joplin organizes notes into notebooks, supports tags, and has a full-text search. It can import notes exported from Evernote in the .enex format, preserving content, images, attachments, and metadata. A browser extension called the Web Clipper lets you save web pages and screenshots directly into Joplin from Firefox or Chrome. The application renders Markdown in a side-by-side editor with live preview. A terminal-based command-line version is also available for Linux, macOS, and Windows via WSL. You would use Joplin if you want a note-taking tool where your data stays under your control, if you are migrating away from Evernote, or if you want a cross-platform Markdown editor with reliable sync. It is a good fit for people who write in plain text and want their notes to remain accessible independently of any single company's service. The tech stack is TypeScript and JavaScript, with the desktop application built on Electron (a framework that wraps web technologies into a desktop app), and mobile apps built natively for Android and iOS.
