- Find public product pages and comparisons to review.
- Support prioritization with evidence from outside the chat.

- 2Create an automation in the portal, or ask Notis to search for product alternatives named in Slack channel messages.
- 3Give one plain-language instruction to find official pages and useful public comparisons for each clear alternative mention.
- 4Select Channel Message Received as the trigger and set the run-report channel.
- 5Test with a message naming a real alternative and the product category.
