This trigger monitors a specific document for structural changes like: - Headers added or removed - Footers added or removed - Tables added or removed - Images (inline objects) added or removed - Positioned objects added or removed - Footnotes added or removed
Action
ASTICA_READ_TEXT
Tool to perform ocr on an image to extract text. use when you need to read raw text from images after confirming the image source.
Why this helps

Questions about this workflow
What starts this workflow?
It starts when Notis detects a supported Google Doc structure change, such as an image count change.
What if the image source is unavailable?
The run should report the missing image source instead of inventing OCR output.
