Amplenote vs QOwnNotes

Amplenote combines notes, tasks, and calendar scheduling in four modes: Jots, Notes, Tasks, and Calendar. It is available through web, Windows, macOS, Linux, iOS, Android, Chrome extension, and API access, with offline use. Users can share notes and collaborate in real time. Tasks can be placed on Amplenote’s calendar and, on Pro or higher, synchronized with Google, Outlook, or Apple calendars. Integrations also include Siri Shortcuts, IFTTT, Pipedream, and Google Drive. The service follows a freemium model with a free plan and 15-day trial. Personal is for non-commercial use and limits uploads to 5 MB; Pro permits larger uploads and unlimited devices, while Unlimited and Founder also list unlimited devices. Native desktop apps require Pro, Unlimited, or Founder, although downloadable PWAs are supported. Standard notes are not end-to-end encrypted by default, and attachments are not encrypted, including with Vault Notes.

QOwnNotes is a free, GPL-licensed note-taking application built around plain-text Markdown files. Notes stay in a folder on your computer, and the app does not sync notes or media itself; you can choose a separate sync client such as Nextcloud or ownCloud. Those services can also provide note sharing, task lists, note history, and access to trashed notes. The editor offers Markdown highlighting and preview, hierarchical tags and subfolders, wiki-style links, Vim mode, and portable mode. Optional encryption includes built-in AES-256 and custom methods such as PGP. You can import from Evernote or Joplin, or work with existing text and Markdown files directly. QOwnNotes is available for GNU/Linux, macOS, Windows, Android, and the web, with a browser extension for clipping selected text, screenshots, and bookmarks. A web companion sends phone photos to the current desktop note. Integrations include Nextcloud, ownCloud, Dropbox, Syncthing, Seafile, CalDAV, and Git. The software is open source, with no paid plans stated.
