What makes it different from Zapier and other automation tools?
No-Code tools are great to automate your daily life. You can connect your Calendar with Notion as well.
The main difference is that those services are too generic to make it work like Notion Automations. You'll end up with complex workflows to achieve what Notion Automations can do for you: Auto-create calendar events from Notion, filter only events that matter to you, adding Notion Link to your events…
Notion Automations just works with a few clicks! And you do not need to pay any extra subscriptions for those Automation tools.
