Find your free slots instantly when availability is requested
Someone DMs asking 'Are you free next week?' Instead of leaving them hanging while you manually check Calendar, Notis scans your availability and replies immediately.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Find free slots
Finds free/busy time slots in google calendars for specified calendars within a defined time range (defaults to the current day utc if `time min`/`time max` are omitted), enhancing busy intervals with event details; `time min` must precede `time max` if both are provided.
Why this helps
People ask for your availability over DM but you don't respond because checking Calendar feels like work. They follow up, you feel bad, and the meeting still doesn't get scheduled—until someone else forces it.
- Respond immediately to availability requests without opening Calendar
- Eliminate the shame of slow responses to simple scheduling questions
- Offer multiple time options at once so people can pick without a follow-up thread
Setup
Build it in a few focused steps.
- 1Connect Slack and Google Calendar to Notis
- 2Create an automation: 'When someone asks me if I'm free over DM, check my calendar and reply with 3 available time slots'
- 3Tell Notis your working hours and timezone so it knows what counts as 'available'
- 4Test by asking a colleague to DM you a hypothetical availability question
Questions about this workflow
Will Notis check any kind of DM or just specific keywords?
You can set it to any DM asking about availability, or refine it to only respond to trusted people or specific phrases like 'are you free' or 'got time'.
What if you have no free time?
Notis will tell the person you're booked and offer to suggest times next week, or you can ask it to suggest alternative dates automatically.
Can I review the response before Notis sends it?
Yes. You can configure it to draft a reply for your approval instead of auto-sending, or set it to send after an hour delay if you want to cancel.
