Amplenote vs Obsidian

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.

Obsidian is a note-taking app for keeping notes and building a personal knowledge workspace. Its core app is free, has no sign-up requirement, and stores notes on the user's device so they remain available offline. It runs on Windows, macOS, Linux, iOS, Android, and as a Chrome extension. Canvas provides an open workspace for research, brainstorming, diagrams, and ideas; thousands of plugins and an open API allow workflow customization. Shared vaults support team work with real-time updates. Sync adds synchronization and version history: Standard costs $5 per user per month billed annually, with one vault, 1 GB of storage, a 5 MB maximum file size, and one month of history. Plus costs $10 per user per month billed annually, with 10 vaults, 10 GB, a 200 MB maximum file size, and 12 months of history. Publish is $10 per site per month billed annually and includes up to 4 GB hosting per site. It offers themes, custom domains, password protection, and SEO optimization.
