Bring the source behind a claim into view
When a team shares a source to support a claim, use Exa to extract relevant content and highlights for easier verification.
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
Get contents from URLs or document IDs
Retrieves configurable text and highlights from a list of exa document ids or publicly accessible urls.
Why this helps
Claims and their sources can become separated in chat, making it harder to confirm what the evidence actually says.
- Keep a claim connected to its public source.
- Surface relevant text for a quicker source check.
- Make review easier before repeating a claim in planning or customer communication.
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 retrieve public source content when a Slack channel message shares evidence for a claim.
- 3Use one plain-language instruction to return relevant highlights and distinguish source text from the original claim.
- 4Select Channel Message Received as the trigger and choose the run-report channel.
- 5Test with a channel message containing a claim and a publicly accessible source URL.
Questions about this workflow
Can it verify every claim as true?
It can retrieve source content and highlights for review, but the team should assess whether the source supports the claim.
Does it work with private links?
The action retrieves publicly accessible URLs or Exa document IDs. Private pages may not be available.
