Explore tool options from a single Slack reaction
When a tool suggestion deserves a closer look, react once and let Exa find comparable products and public information for 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
Search
Performs a web search using the exa engine, useful for queries requiring advanced filtering, specific content categories, or ai-optimized prompting.
Why this helps
Tool ideas can lead to open-ended searches that consume focus before the team has agreed on what to compare.
- Capture tool ideas without stopping to search.
- Find related product options and public details.
- Give the team a starting point for a bounded comparison.
Setup
Build it in a few focused steps.
- 1Connect Slack and Exa to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to search for comparable tools when a Slack message gets the agreed reaction.
- 3Write one plain-language instruction asking Exa for relevant alternatives and public product pages.
- 4Select Message Reaction Added as the trigger, add the agreed emoji filter if desired, and choose a report channel.
- 5Test by reacting to a message that names a tool and its use case.
Questions about this workflow
Does Exa guarantee a complete list of alternatives?
No. Search results are a research starting point, so review sources and coverage before choosing a tool.
Can I use a dedicated reaction for this?
Yes. The reaction event supports filtering by emoji name.
