Joplin

Joplin is an open-source note-taking application designed to help users capture, organize, and access their thoughts and information across multiple devices. It supports various note types, including multimedia notes with images, videos, PDFs, and audio files, and allows for the creation of math expressions and diagrams directly within the app. Users can also save web pages and screenshots as notes using a web clipper extension for Chrome and Firefox. The application emphasizes data ownership and privacy, saving notes in an open format and offering end-to-end encryption (E2EE) to ensure that only the user can access their data. Joplin provides flexible synchronization options, including its own Joplin Cloud service, as well as third-party services like Dropbox and OneDrive. With Joplin Cloud, users can also collaborate on notebooks, publish notes to the internet, and manage multiple users for team environments. It is available on Windows, macOS, Linux, Android, iOS, and even as a terminal app, catering to a wide range of users from individuals to teams seeking a secure and customizable note-taking solution.
