Joplin

Joplin is an open source note-taking application that lets you capture your thoughts and access them securely from any device. You can create notes in Markdown or Rich Text format, attach files like images and PDFs, and even create math expressions and diagrams. Your data is saved in an open format, and with Joplin Cloud, Dropbox, or OneDrive synchronization, your notes are available on your computer, phone, or tablet. The app also includes a web clipper for browsers to save web pages or take screenshots directly into your notes.

What sets Joplin apart is its strong focus on privacy and flexibility. It uses End-To-End Encryption (E2EE) to ensure that no one but you can read your notes. The app is highly customizable with plugins and themes, and it offers an Extension API for creating your own scripts. Joplin Cloud, based in France, provides a collaboration platform for sharing notes with others or publishing them online, all under strict EU privacy laws.

Joplin is ideal for students, researchers, and professionals who need a reliable, private, and cross-platform system for organizing information. It works well for personal journaling, academic research by clipping online sources, and team collaboration on projects through Joplin Cloud. Its open source nature and focus on data ownership make it a strong choice for users who prioritize control over their digital notes.
