2sync

What it is

2sync is a Notion automation tool. It keeps Notion databases in two-way sync with Google Calendar, Outlook and Todoist, brings Gmail into Notion one way, and the company says a change in one app shows up in the other within minutes. The idea is that Notion becomes the one place where your calendar, tasks, contacts and mail live, without you copying anything by hand.

It is aimed at individuals and small teams who already run their day from Notion and are tired of re-entering the same event or task in two apps. It is not a general builder of apps or multi-step flows; it is a productivity sync tool for calendars, tasks, contacts and email. The footer of the site describes it as a tonoïd microstartup, made in Bordeaux. One long-time reviewer notes that the service used to be called Notion Automations.

What you build and how

What you build with 2sync is an automation: one link between a Notion database and one outside app, with a field map and a direction for each field. There is no canvas, no code and no scripting. You work in the 2sync dashboard.

The setup, as the company's FAQ lays it out, has 4 steps. Connect your Notion workspace and your Google account, select the database and the calendar you want to link, map the fields, then activate the automation. The company says the first sync starts within minutes and that no code or complex setup is required. The company says Outlook changes sync automatically on the same schedule as the Google Calendar integration.

The integration list is specific. 2sync connects Notion with Google Calendar, Google Tasks, Google Contacts, Gmail, Outlook Calendar, Outlook Contacts, Outlook Mail, Microsoft To Do and Todoist. Calendar and task integrations are two-way. Email integrations are one-way into Notion, so a Gmail or Outlook message lands as a record in a database but nothing flows back to the inbox. Contacts sync both ways for Google Contacts and Outlook Contacts. A Google Sheets integration is also listed, described as syncing a Google Sheets tab with Notion, both ways. The navigation also carries a "Vote for integrations" link where visitors tell the company which app they want next.

The homepage lists what each automation can do: map any Notion property to any field in the connected app, with support for all Notion property types, filter which items sync, and resolve conflicts with built-in conflict resolution. Syncs run in the background from every 2 minutes to daily, with sync history, detailed logs and email alerts when something needs your attention. The company says setup takes under 5 minutes.

Direction is the main control you have. For each field you can choose to sync in both directions, one way to Notion, or one way to Google Calendar. That matters in practice. You might want an event title to travel both ways but a description to stay one-directional so edits made in the calendar never overwrite notes you keep in Notion. Create an event in either app and it appears in the other within minutes, and the company says updates can arrive as often as every 2 minutes.

Calendar sync is the headline use. The FAQ states that Outlook Calendar syncs two-way with Notion databases, and that Outlook Contacts and Microsoft To Do sync both ways too, with Outlook Mail coming into Notion one way. Todoist projects and tasks sync into a Notion database.

Apple Calendar is the limit. The FAQ says it has no public API, so 2sync cannot connect to it directly. The workaround it gives is to sync Apple Calendar with Google Calendar or Outlook Calendar, after which 2sync keeps Notion in two-way sync with that calendar and Apple Calendar stays updated through the shared connection.

On data handling, the FAQ says 2sync processes your data to perform the sync but does not store copies. Only connection metadata and configuration settings are saved, and the data stays in Notion and your connected accounts.

The company also publishes a changelog, documentation, a blog and an affiliate program that pays commissions. Its blog covers Notion integrations, calendar apps and task apps, with posts such as comparisons of Microsoft To Do and Google Tasks.

The evidence from the pages

Pricing is on the page. Plans start at $7 a month billed annually, or $9 a month billed monthly, for one automation with syncs every 5 minutes. Premium and Pro plans add more automations, faster sync frequency, a longer sync time window and unlimited synced items. Every plan includes a 14-day free trial, and the site says you can cancel anytime. There is a trial, not a free plan.

A company comparison page names the entry plan Solo and says it syncs up to 3,000 items, with Premium and Pro unlimited. The homepage claims 4K+ active syncs, 18M+ Notion pages synced and a 4.97/5 average user rating, and lists customer stories from a district sales manager who built a personal operating system in Notion, a creative consultant who replaced standalone CRM tools by syncing Google Calendar, Tasks and Contacts, and a freelance designer who runs 2 businesses from Notion with Todoist and Calendar.

Reviews on the home page are mixed in a useful way. One reviewer who chose the Todoist and Notion integration says it syncs fast and reliably and that the setup and sync dashboard are straightforward. Their downsides are a Notion and Todoist API that is still quite limited, which they place on those two products rather than on 2sync, and a price they call too high, since the 2sync subscription costs more than the Todoist subscription itself. Win, a consultant, wrote that review. Paweł Kubryński, a lead programmer, writes that it does its job and that he got quick help with an edge-case problem. Dean Allen says it syncs his tasks into Notion through the Todoist integration, calls it a paid service worth paying for, and says support answered his question promptly. Furkan Menekşe, a founder, says he has used it "with great satisfaction for 3 years", and Eric Charles Welton describes the team as responsive when calendars synced across multiple time zones raised edge cases.

Support runs through a chat with the team (the FAQ says to "chat to our friendly team"), a contact page and a send-feedback link.

Who it suits and who it does not

A solo founder or freelancer who plans in Notion and keeps client meetings in Google Calendar or Outlook gets the most from it. So does an ops lead who wants a team's Todoist projects visible next to Notion project pages. The company says setup takes minutes.

It is a weaker fit if your data lives in a database or CMS rather than in calendar, task, contact and mail apps, since those are the integrations it lists. It does not reach Apple Calendar directly. The single-automation entry plan, at $7 or $9 a month, means each additional pairing needs a higher plan, and a reviewer found the price steep next to Todoist's own. And if you need multi-step logic, conditions or actions across dozens of apps, a general automation platform is the better tool.
