What is 2sync
2sync automatically syncs Notion with Google Calendar, Outlook, Todoist, and more. True two-way sync with field mapping, filters, and team collaboration.
2sync is a two-way synchronization platform that connects Notion databases with productivity apps like Google Calendar, Outlook Calendar, Todoist, Google Tasks, Google Contacts, Outlook Contacts, Gmail, and Outlook Mail.
Unlike Notion Calendar, which shows events as a read-only overlay, 2sync creates real Notion database pages, giving you access to formulas, rollups, relations, and custom properties. Changes sync automatically in both directions within minutes.
Who is 2sync for?
- Professionals juggling multiple tools: Keep your work calendar, personal calendar, and Notion task database in sync without switching apps.
- Teams using Notion as a central hub: Sync individual team members' calendars to a shared Notion workspace with shared connections.
- Freelancers and consultants: Auto-log client meetings from Google Calendar into a Notion CRM using relations.
- Students: Sync class schedules and assignment deadlines between calendar apps and Notion.
- Anyone tired of copying data manually: Make a change in one place and see it reflected everywhere, automatically.
All plans come with a 14-day free trial, so you can try 2sync with your own workflow before paying.

How does 2sync work?
Two-way synchronization
2sync monitors both Notion and your connected apps for changes. When something updates, it syncs automatically:
- Create an event in Google Calendar → appears in Notion
- Edit the event in Notion → updates in Google Calendar
- Delete from either app → syncs based on your settings
Field mapping & sync direction
Control how data transfers between apps and set sync direction per field: two-way, one-way to Notion, or one-way to provider. Configure each field in your field mapping settings.
Filters
Sync only what matters by using filters to pick specific calendars, certain labels, or items matching your conditions.
Relation database sync
Automatically link data across Notion databases with relations. Map calendar attendees to a Contacts database, connect Todoist tasks to Projects, or link email senders to your CRM.
What makes 2sync different?
- Real database pages: Unlike Notion Calendar's overlay, every synced item becomes a full Notion page with formulas, rollups, and relations.
- True two-way sync: Changes flow both directions automatically, no complex multi-step automations needed.
- Field-level sync control: Set sync direction independently for each mapped field.
- Shared connections for teams: One person connects their account, and team members sync their own data to a shared database.
- Privacy by design: Data is processed in volatile memory and discarded after each sync cycle. Nothing is stored on disk.
How does 2sync compare?
2sync vs. one-way sync tools
Notion Calendar shows events as a visual overlay, and Notion to Calendar offers one-way iCal feeds, but neither creates actual database pages. 2sync does: every synced item becomes a full Notion page with two-way sync, formulas, rollups, and relations.
| Feature | Notion Calendar / Notion to Calendar | 2sync |
|---|---|---|
| Sync direction | One-way | Two-way |
| Events as database pages | No | Yes |
| Formulas, rollups & relations | No | Yes |
| Custom Notion properties | No | Yes |
| Supported apps | Google Calendar, iCal-compatible apps | 8 integrations (calendars, tasks, contacts, email) |
| Field mapping control | No | Per-field direction |

2sync vs. automation platforms
Zapier, Make, and Unito can connect Notion to other apps, but they're general-purpose automation tools that aren't optimized for Notion sync.
| Feature | Zapier / Make / Unito | 2sync |
|---|---|---|
| Two-way Notion sync | Multiple automations + custom logic | Built-in |
| Deduplication | Manual setup or basic | Automatic |
| Conflict resolution | DIY or basic | Automatic |
| Relation database sync | No | Yes |
| Notion-specific optimization | Generic | Purpose-built |
| Pricing model | Per-task / per-operation / per-flow | Flat subscription, unlimited items |

FAQ
What's the difference between 2sync and Notion Calendar?
Notion Calendar displays events as an overlay but doesn't create database pages. 2sync imports data as actual Notion pages, enabling formulas, relations, rollups, and custom properties. It also supports two-way sync across 8 integrations—not just calendars.
How is 2sync different from Zapier or Make?
2sync provides continuous two-way sync out of the box. With Zapier or Make, you'd need multiple automations, custom deduplication logic, conflict resolution, and a state tracking database to achieve the same result. 2sync handles all of that automatically.
What apps does 2sync work with?
2sync connects Notion with Google Calendar, Outlook Calendar, Todoist, Google Tasks, Google Contacts, Outlook Contacts, Gmail, and Outlook Mail. Calendar, task, and contact integrations support two-way sync. Email sync is one-way to Notion.
Is my data stored by 2sync?
No. 2sync processes data in volatile memory and discards it after each sync cycle. Only minimal metadata—connection IDs, field mappings, and sync timestamps—is retained. Your events, emails, tasks, and contacts are never written to disk.
Can I try 2sync before committing?
Yes. Every plan includes a 14-day free trial. Sign up, test it fully with your own workflow, and you won't be charged until the trial ends. Cancel anytime during the trial at no cost.
How fast does 2sync sync changes?
Sync frequency depends on your plan: every 2 minutes on Pro, 3 minutes on Premium, or 5 minutes on Solo. You can also click Sync Now on any automation to trigger an immediate cycle.
Can multiple team members sync to the same Notion database?
Yes. One person connects their account and generates a shareable link. Team members use that link to sync their own calendars or tasks to a shared Notion database. Each person needs their own 2sync plan.
Can I sync only certain events or tasks?
Yes. 2sync supports filters so you can sync only items matching specific conditions—for example, only your Work calendar, only high-priority tasks, or only events with certain keywords. Configure filters when creating your automation or adjust them anytime.
