Make Slack ideas easier to try
Give a promising idea a small, testable next shape without turning it into a large planning exercise.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Generate Content (Gemini)
Generates text content from prompts using gemini models. supports various models like gemini flash and pro with configurable temperature, token limits, and safety settings for diverse text generation tasks.
Why this helps
Ideas shared in Slack can pile up without an obvious first experiment or way to learn from them.
- Translate a broad idea into a first test.
- Define a simple learning signal.
- Reduce friction between idea capture and action.
Setup
Build it in a few focused steps.
- 1Connect Slack and Gemini to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to shape Slack product or growth ideas into experiment briefs.
- 3Describe the brief format in one plain-language instruction, asking for assumptions to be labeled.
- 4Select the Channel Message Received trigger and choose a channel for run reports.
- 5Test with a real idea message and review whether the suggested test is practical.
Questions about this workflow
Will Gemini know whether an idea is ready to test?
Ask it to identify missing assumptions and keep its experiment suggestion proportional to the idea.
Does this launch the experiment?
No. Gemini drafts the brief; a person chooses whether and how to run it.
