Know Who You're Meeting Before the Call
Clarity prevents surprises. When someone schedules a new meeting with you, Notis sends a Slack alert with all attendees listed, so you immediately know the meeting scope and who to expect.
Trigger
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
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
ADHD-related working memory challenges mean founders often forget who's invited to a meeting until the moment it starts. This creates social anxiety, missed context, and a scramble to gather your thoughts. Knowing attendees in advance allows mental prep.
- Mentally prepare based on who's attending
- Avoid the anxiety of discovering surprise attendees mid-call
- Adjust your communication style for the group size
- Quickly identify if you're missing a key stakeholder
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Slack to Notis.
- 2Create an automation called 'New Meeting Attendee List'.
- 3Write this prompt: 'When a new event is created on my calendar, send me a Slack alert with the event title, time, and a complete list of all attendees. Include their names and email addresses for quick reference.'
- 4Set the trigger to 'Event Created'.
- 5Choose a Slack channel for these alerts.
- 6Test by having someone add an event to your calendar with multiple attendees.
