React to Slack messages from Discord signals
A Discord message lands marked as 'important' or 'needs review.' Notis adds a reaction emoji to the corresponding Slack message, making status and urgency visible at a glance without manual work.
Trigger
New Discord Message Trigger
Polls a specific Discord channel for new messages.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Status and priority signals get lost across platforms; visual indicators require manual coordination and are often forgotten.
- Add visual status signals across platforms automatically
- Preserve context and priority indicators
- Reduce manual coordination overhead
- Build clear, visual communication systems

- 3Choose the trigger: New Discord Message from your prioritized channel
- 4Select the Slack reporting channel

Questions about this workflow
Which emoji reactions are added?
You specify in your prompt. Common ones are š, š“ (urgent), or š (new), but any emoji works.
How does Notis match Discord and Slack messages?
It uses content matching and context. Your prompt can clarify: 'match by the topic or title'.
Can different signals trigger different reactions?
Yes. Your prompt can set logic: 'if urgent, add š“; if needs review, add š'.
