Action
GAN AI Text-to-Speech

Why this helps
Stopping to read a useful post immediately can break a task, but leaving it unmarked makes it easy to forget.
- Capture a message for listening with a single reaction.
- Avoid breaking focus to read a post the moment it arrives.
- Build an easier way to revisit selected Slack context.
Setup
Build it in a few focused steps.
- 1Connect Slack and Gan ai to Notis once in the portal.
- 2Create an automation asking Notis to make a concise spoken version of the reacted-to message using Gan ai text-to-speech.
- 3Choose Slack Message Reaction Added, select the intended emoji if desired, and choose a run-report channel.
- 4Test with one real message and confirm the reaction starts the audio workflow.
Questions about this workflow
Does this create a playlist?
No. It generates speech when the reaction is added. The action does not organize clips into a playlist.
Can I pick which messages qualify?
Use a reaction trigger and choose a deliberate emoji to mark the messages you want Notis to process.
