PDF Read OCR

Hi All,

I have requirement to read content of PDF having Table and Paragraphs which is structured and unstructured and store it into TABLES without any manual intervention.

I have used the Appian inbuilt feature doc extract but its not providing me accurate reading capability like some fields are readable but some are not. 

https://docs.appian.com/suite/help/23.2/evaluate-doc-extraction.html

We would like to stick with Appian as it keeps the doc in Appian rather than using Google 

Any suggestion will be helpful

Thanks
