Never miss a Slack mention by turning it into a calendar event
Context gets scattered across Slack channels. When you're mentioned, Notis creates a calendar event with the message thread so you can review it at the right time instead of scrolling endlessly.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Create Event
Creates an event on a google calendar, needing rfc3339 utc start/end times (end after start) and write access to the calendar. by default, adds the organizer as an attendee unless exclude organizer is set to true.
Why this helps
You're mentioned in a channel but the context is buried. By the time you check Slack again, the discussion is resolved and you've missed the chance to contribute or stay informed.
- Receive an external calendar reminder when you're mentioned instead of relying on Slack notifications
- Prevent dropped discussions by surfacing mentions at a predictable time
- Keep all mentions in one place (your calendar) instead of hunting through channels
Setup
Build it in a few focused steps.
- 1Connect Slack and Google Calendar to Notis (one-time setup in the portal)
- 2Create an automation by telling Notis: 'When I'm mentioned in a Slack channel, create a calendar event'
- 3Choose a channel where Notis reports automation runs
- 4Select the 'Channel Message Received' trigger and wait for your next mention to test
Questions about this workflow
Will this create an event for every Slack mention?
Yes. You can ask Notis to filter by specific channels or keywords if you'd like fewer events—for example, only mentions in your #urgent channel.
What time will the event be created?
Immediately when the mention happens. Notis uses the message timestamp and creates the event so you can follow up.
Can I customize what's included in the calendar event?
Absolutely. Tell Notis to add the full message text, thread link, or just the person's name—whatever helps you remember.
