Never Lose an Action Item Mentioned in Slack

Your team mentions action items in passing ('we need to fix the signup flow'), but they don't show up in your to-do list. Tag them #action in Slack and Notis sends a WhatsApp reminder.

Trigger

Channel Message Received

Send message

Send a text message to a whatsapp number. note: the message will reflect on the recipient's phone number only if they have texted first.

Why this helps

Action items get discussed in Slack but never formalized. You remember some, forget others, and end up repeating work or over-committing because you didn't track them.

  • Catch action items as they're mentioned
  • No extra Slack workflows to learn
  • Clear list of what you own
  • Reduce repeated conversations

Setup

Build it in a few focused steps.

  • 1Connect Slack and WhatsApp to Notis.
  • 2Create automation: 'When someone mentions #action in a Slack channel, send me that action item on WhatsApp.'
  • 3Your team adds #action tags naturally in Slack (e.g., '#action fix the bug in signup').
  • 4Notis extracts the item and sends it to WhatsApp with context.
  • 5Respond on WhatsApp: 'Got it' or 'Need more info'—Notis logs your status back to Slack if useful.

Questions about this workflow

What if people forget to tag #action?

You can ask Notis to watch for keywords like 'we should,' 'need to,' or 'fix' instead. It's less precise but catches more.

Does this work across all channels?

Yes. Notis can filter by channel if you want only #action items from #product-decisions, for example.

Can I prioritize action items from WhatsApp?

Yes. Tap 'Priority: high' or 'Assign to later' on WhatsApp and Notis updates your task system.
