Amplenote vs Open Keep

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.
