Why this helps
Transcribing every brainstorm is busywork, but leaving the useful ones as photos makes follow-up harder.
- Request extraction only for chosen photos.
- Turn selected handwritten ideas into a text reference.
- Avoid adding a separate transcription request.
Setup
Build it in a few focused steps.
- 1Connect Slack and Astica ai to Notis once in the portal.
- 2Create the automation in the portal or ask Notis in plain language.
- 3Tell Notis to OCR a whiteboard photo when a chosen reaction is added to its Slack message and report the result with context.
- 4Select Slack Message Reaction Added and a channel for run reports.
- 5Test by reacting to one whiteboard photo.
Questions about this workflow
Will it extract every handwritten word perfectly?
OCR quality depends on legibility. Check the image for unclear writing.
Can I use it for other image types?
The instruction can focus the workflow on whiteboard photos, which keeps this use case specific.
