Keep extracted text current as images change

When a Drive image is updated, re-run OCR so the text you review reflects the latest file.

Trigger

File Updated

Triggers when a file's metadata or content changes in Google Drive.

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

After replacing or correcting a scan, older extracted text can linger in notes and decisions.

  • Refresh OCR after an image revision
  • Reduce reliance on text from an older scan
  • Keep the review step close to the file update

Setup

Build it in a few focused steps.

  • 1Connect Google Drive and Astica ai once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and name it for refreshed OCR.
  • 3In one instruction, ask Notis to analyze the updated image with Astica OCR and return the new extracted text.
  • 4Pick the Google Drive File Updated trigger and choose where run reports go.
  • 5Test by updating one real image file and checking the returned text.

Questions about this workflow

Does this run for every Drive change?

This workflow uses the File Updated event, which triggers when a file's metadata or content changes. Review your real example to confirm it suits the files you intend to process.

Does OCR guarantee the text is correct?

No. Review the returned text against the source image, especially for small, blurred, or handwritten text.

TriggerPolling

File Shared (Permissions Added)

Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
