OCR services
OCR services are used for the following purposes:
- At data labeling time, when importing documents into Document Manager. The engines available for this step are UiPath® Document OCR, Google Cloud Vision OCR, and Microsoft Read OCR.
- At run time when calling models from RPA workflows. The engines available for this step are all the engines integrated with the UiPath RPA platform including the above, plus Microsoft OCR (legacy), Microsoft Project Oxford OCR, and Tesseract.
In production, we recommend calling the OCR using the Digitize Document activity in your workflow and passing the Document Object Model as input to the activity calling the ML model. For this purpose, you need to use the Machine Learning Extractor activity (Official feed).
As a quick convenience for testing purposes, you can also configure the OCR directly in AI Center (Settings window), but this is not recommended for production deployments.
The table below shows how to configure the six supported OCR engine types in both Document Manager and AI Center.
ocr.method argument corresponds to the OCR Engine dropdown in the ML Package creation view in AI Center.

while you are using a deployment type other than Automation Cloud, such as Automation
Suite offline, you need to add the API key from an Automation Cloud account. Make sure
that you use the Automation Cloud API Key for public endpoints, and the Automation Suite
API Key for endpoints hosted within Automation Suite.
