Why this helps
Important messages get acknowledged but their next step can still slip out of view.
- Use an existing reaction as a lightweight attention cue.
- Create a compact description of the message to revisit.
- Reduce the need to reconstruct context later.
Setup
Build it in a few focused steps.
- 1Connect Slack and Ai ml api to Notis once in the portal.
- 2Create an automation in the portal or ask Notis in plain language.
- 3Give one instruction: when a reaction is added to a Slack message, generate a short summary of the message and any explicit follow-up it contains.
- 4Select Message Reaction Added as the trigger and choose a channel for run reports.
- 5Test by reacting to a message with a clear follow-up.
Questions about this workflow
Can the reaction itself determine priority?
A reaction can trigger the workflow, but the generated summary should rely on the message content and your instruction.
Can the trigger be restricted to an emoji?
