| Account required | No, for local use; optional for sync | Yes – a Notion account is mandatory, even for solo use |
|---|
| Local editing | Fully local, no cloud requirement | No true offline-first mode; data lives exclusively on Notion's servers, the desktop app only caches for up to 72 hours |
|---|
| Encryption | Optional sync is client-side AES-256-GCM encrypted with a separate passphrase | AES-256 at rest on the server and TLS in transit, but no end-to-end encryption |
|---|
| Operating systems | macOS and Windows (iOS in preparation) | macOS, Windows, iOS, Android, and web – fully cross-platform |
|---|
| Reminders & calendar | To-dos with due dates, priority, and a calendar overview of selected calendars | Calendar view and reminders as a configurable database feature; no access to the system calendar |
|---|
| Organization | Projects, tags, note templates, and local full-text search | Very flexible databases, nested pages, and templates – considerably more powerful, but also more complex |
|---|
| Collaboration | Currently focused on personal devices and sync, no real-time collaboration | Mature real-time collaboration, comments, shared workspaces, and guest access – Notion's core strength |
|---|
| Price | Free basic feature set; advanced features may be offered as paid later | Free plan with unlimited pages for solo users (7-day version history, 5MB file limit); Plus plan from $10/member/month |
|---|
