Never Be Caught Off-Guard When a Meeting Starts

Give yourself a buffer to get ready. Notis sends a Slack reminder a few minutes before each meeting, so you can gather your notes, close other tabs, and show up focused.

Trigger

Event Starting Soon

Triggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available.

Action

Create a reminder

Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').

Why this helps

Neurodivergent founders often experience time blindness or hyperfocus that causes them to miss meeting starts entirely or show up unprepared. A small prep reminder prevents embarrassment, late arrivals, and the cognitive overload of scrambling into a call.

  • Mental preparation time before high-stakes calls
  • Opportunity to find meeting notes or agendas in advance
  • Reduce the shock of a meeting starting without notice
  • Less context-switching chaos as you enter calls

Setup

Build it in a few focused steps.

  • 1Connect Google Calendar and Slack to Notis.
  • 2Create an automation in the portal called 'Meeting Prep Reminder'.
  • 3Write this prompt: 'Send me a Slack reminder 10 minutes before each calendar event starts, including the meeting title and any attendees.'
  • 4Set the trigger to 'Event Starting Soon' and configure it for 10 minutes before.
  • 5Choose your Slack channel for these reminders.
  • 6Test with your next upcoming meeting by checking for the Slack alert.

Questions about this workflow

How much advance notice can I get?

You can set Notis to remind you anywhere from 5 to 60 minutes before. Tell Notis your preference in the prompt.

Will I get reminders for all-day events?

No, all-day events don't have specific start times, so this automation skips them.

Can I skip reminders for certain meetings?

Yes. Tell Notis: 'Don't remind me about 1-on-1s' or 'Skip calendar blocks called Focus Time.'
