Trigger

Action

Why this helps
Reading and retyping document details interrupts focused work and makes follow-up harder to resume.
- Create readable text from a document image.
- Keep the extraction tied to the originating DM context.
- Make follow-up easier to resume after other work.
Setup
Build it in a few focused steps.
- 1Connect Slack and Astica ai to Notis once via the portal.
- 2Create an automation in the portal or ask Notis for it in plain language.
- 3In one instruction, ask Notis to OCR document images received in DMs and report only the extracted visible text with context.
- 4Pick Slack Direct Message Received and a channel for Notis run reports.
- 5Test with one suitable document image.
Questions about this workflow
