Protect time for high-priority work with one reaction
You see a critical task mentioned in a Slack thread. React with 🔥 and Notis blocks 2 hours on your calendar for that work—making it real instead of stuck in your head.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Quick Add Event
Parses natural language text to quickly create a basic google calendar event with its title, date, and time, suitable for simple scheduling; does not support direct attendee addition or recurring events, and `calendar id` must be valid if not 'primary'.
Why this helps
You know what your top priority is but you never actually protect time for it. It stays in your head as 'important' while urgent messages pull you away, so it never gets done.
- Externalize your priority by putting it on your calendar so you're less likely to forget
- Protect time for what matters most instead of reactive urgent work
- Build accountability by having priorities visible on your calendar
Setup
Build it in a few focused steps.
- 1Connect Slack and Google Calendar to Notis
- 2Tell Notis: 'When I react with 🔥 to any message, block 2 hours on my calendar for that priority'
- 3Choose your preferred duration (90 min, 2 hours, 4 hours) and time of day
- 4Test by reacting to a message in any Slack channel
Questions about this workflow
What if you don't have 2 hours available?
Notis will find your next available 2-hour window and suggest it, or you can adjust the duration to fit what's available.
Can you prioritize multiple things at once?
Yes. Each reaction creates a separate calendar block, and you can see all of them to decide which to tackle first.
What if you finish the priority work early?
You can delete the calendar event or use the freed-up time for other priorities.
