Why this helps
Expense receipts sent as images interrupt focused work and require manual reading before anyone can follow up.
- Capture visible receipt text in a readable run report.
- Make expense review easier to resume later.
- Avoid retyping basic receipt details by hand.
Setup

- 1Connect Slack and Astica ai to Notis once in the portal.
- 2Create the automation in the portal or ask Notis to set it up in plain language.
- 3Tell Notis to use Astica ai OCR on receipt images posted in the selected channel and return the extracted text with the Slack context.
- 4Select Slack Channel Message Received as the trigger and choose a run-report channel.
- 5Test with one real receipt image shared in Slack.
Questions about this workflow
