- Make visual inspection more convenient.
- Reduce the setup work before feedback begins.

- 2Create an automation in the portal or ask Notis to create JPG page assets for PDFs shared in the channel.
- 3Use a single plain-language instruction to define the file to process and the desired reporting.
- 4Select Channel Message Received as the trigger and choose a run-report destination.
- 5Test with a layout-heavy PDF that needs review.
