UiPath OCR engine advantage and disadvantage

  • Google OCR – It is very user-friendly and easy to use because it’s built into UiPath, but I found that it is the slowest option. Multi-page documents can take upwards of 30 seconds to get through.
  • Google Cloud OCR – It is more fast option and accurate. I was able to create an API key and get it working with UiPath pretty quickly. I did have to turn on billing to get the API key to work, but they give you 1,000 pages per month for free, which was more than enough for what I was doing. It is more robust.
  • Microsoft OCR – Microsoft Oct is similar to the built-in Google OCR option in that it’s free and easy to use. For some document types, it was more accurate than Google OCR, but for others, it was less accurate.
  • Microsoft Cloud OCR – I signed up for an API key, but I got an error in UiPath when I tried to use it. Based on some research I’ve done, I’m not the only one having this issue. It might have to do with some changes to Microsoft’s API that have not yet been reflected in UiPath.
  • Abbyy OCR – It is a free trial, you can download the trial version of Abbyy FineReader to the machine I was using, and I was very impressed. FineReader can do lots unique and beautiful feature including converting a scanned PDF to a searchable PDF or other document formats.
  • Abbyy Cloud OCR – I signed up for a free trial of this service, and it was easy to get it working with UiPath. This option was fast and accurate like Google Cloud OCR. Abbyy really shines in the way it formats the output text — the text is spaced out to mimic the spacing of the original PDF, whereas most of these options simply output the text line by line.
