Make design annotations easier to read
When a design screenshot needs a closer text read, react to it and get its visible copy extracted for review.
Trigger

Action
ASTICA_READ_TEXT

Why this helps
Tiny labels and annotations in design screenshots can slow review and make feedback hard to reference.
- Read screenshot labels without repeated zooming.
- Reference visible annotations more easily in discussion.
- Keep review focused on the design decision.
Setup
Build it in a few focused steps.
- 1Connect Slack and Astica ai to Notis once using the portal.
- 2Create an automation in the portal or ask Notis to create it conversationally.
- 3Write one instruction asking Notis to OCR design screenshots when the chosen reaction is added and report the visible text with source context.
- 4Pick Slack Message Reaction Added and choose where Notis reports runs.
- 5Test with one annotated design screenshot.
Questions about this workflow
Will it interpret the design feedback?
No. Astica ai OCR extracts visible text; interpretation remains for the team.
Can a reaction be the request to process only selected images?
Yes, describe that cue in the plain-language instruction and select the reaction filter if available.
