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

Responsibilities get assigned in Box but don't stick in your memory. You discover forgotten tasks days later, missing deadlines.

  • New assignments trigger immediate Slack reminders
  • Prevents forgotten or overlooked responsibilities
  • Keeps action items front and center
  • Reduces cognitive load of remembering assignments

Setup

Build it in a few focused steps.

  • 1Connect Box and Slack to Notis.
  • 2Create an automation: 'Create a Slack reminder whenever a new assignment is added to a task on this Box file.'
  • 3Select the Box file or task to monitor.
  • 4Configure when the reminder should appear (immediately or at a set time).
  • 5Test by adding a task assignment and verify the Slack reminder.

Questions about this workflow

What's the difference between a reminder and a message?

Reminders are sticky and persistent in Slack, designed to keep tasks in your focus. Messages can get lost in the conversation flow.

Can I set a specific reminder time?

Yes. You can tell Notis to create the reminder for a specific time, or trigger it immediately when the assignment is made.

Does this work for all task assignments or just mine?

You can customize it to trigger only for assignments to you, or for all assignments to a specific file.
