Joplin

Joplin is a free, open source note taking and to-do application for Windows, macOS, Linux, Android, and iOS. It handles large note collections organized into notebooks, with searchable Markdown notes that can be copied, tagged, and edited in the apps or in your own text editor. It is offline first, so notes stay on your phone or computer and remain available without internet.

It can import Evernote exports, converting formatted content to Markdown while keeping resources such as images and attachments and complete metadata. Plain Markdown files can also be imported. Sync supports end-to-end encryption with Nextcloud, Dropbox, OneDrive, and Joplin Cloud. Full text search is available on all platforms.

Joplin can be customized with plugins and themes, and users can create their own. Full text search works across all platforms, and the Web Clipper for Firefox and Chrome saves web pages and screenshots straight into your notes.
