Notis

Mark it once, get a useful summary

Use a familiar reaction to flag a message for a short, structured review.

Trigger

Message Reaction Added

Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.

Action

Execute Code

Execute python code in a sandbox and return any result, stdout, stderr, and error. use /home/user folder to write/read files. try to not use plt.show() as the code is executed remotely. use files for image/chart output instead.

Why this helps

Important messages are hard to distinguish from the volume of conversation without adding another tracking process.

  • Flag a message with a quick reaction.
  • Receive a compact summary with a suggested next step.
  • Avoid copying long messages into notes by hand.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Codeinterpreter to Notis once.
  • 2Create an automation with a plain-language prompt describing the summary and next step to prepare.
  • 3Pick Message Reaction Added as the trigger and choose a report channel.
  • 4Test by adding the selected reaction to one real message.

Questions about this workflow

Can I use a reaction as the only signal?

Yes. The Slack trigger supports reaction events; describe your intended use of the reaction in the prompt.

Can the summary include decisions and tasks?

Ask Notis to separate decisions, requests and suggested next steps when those details appear in the message.
