Find mutual meeting slots from your notes
Turn scheduling constraints into a short list of workable times.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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
Availability, preferences, and constraints are scattered across source material and calendars.
- Combine constraints with real availability
- Return a small set of options
- Reduce scheduling back and forth

- 2Create a mutual-slot automation.
- 3Tell Notis to read meeting constraints from BrainGraph and find matching free slots within the requested range.
