Why this helps
Important links arrive in DMs and are hard to revisit during a packed day.
- Preserves a visual copy of a page from a private handoff.
- Creates a consistent review artifact for later decisions.
- Helps founders process links in focused batches.

- 2Create an automation named DM link screenshot.
- 3Tell Notis to extract the first public URL from each new DM and capture a screenshot for review.
- 4Pick Direct Message Received as the trigger and choose where run reports go.
- 5Test with one real DM containing a link.
Questions about this workflow
Does this read channel messages too?
No. This workflow uses the Direct Message Received event and only processes DMs.
Can it handle several URLs in one DM?
Ask Notis to capture each public URL, or specify that it should use only the first URL.
