Joplin

Joplin is an open-source cross-platform app that provides a system for managing notes and to-do lists. It allows users to organize a large volume of information into notebooks, utilizing tags and search functions to locate specific entries. The software is available as a desktop application for Windows, Linux, and macOS, as well as a mobile app for Android and iOS.

The application follows an offline-first approach, storing all data locally on the device to ensure accessibility without an internet connection. Users can synchronize their data across multiple devices using various cloud storage providers or a dedicated cloud service. A browser extension for Chrome and Firefox is also available to capture web pages and screenshots, which can then be saved directly into the note database.
