UiPath Screen OCR: Now in Public Preview!

This is pretty awesome! I haven’t found any real issues. Mainly using it to read pdfs


Can i use this for Digitize document (Intelligent OCR activities ) ? If that is possible i used getting error

I’ve tried to use the UiPath Screen OCR to look at an image to see if it can get better results than the Microsoft OCR engine.

What I’m doing is putting an image into an image file using the Load Image activity. I then pass that image file into the OCR engine and have a String variable in the Text location of the activity.

My results for the Microsoft OCR Engine is some of the text from the image (sometimes correct, sometime incorrect).
My results for the UiPath Screen OCR Engine is the error “Error performing OCR: An error occurred while sending the request. ScreenOCRErrorRunningEngine”

I’m unsure if there is an error in how I set this up or not. I’ve tried it in the Computer Vision screen recording and was able to get some results, but not many.

Any help would be appreciated…

i am facing problem in the last days with this

Perfect. It doesnt work


I’ve been using the UiPath Screen OCR since the day it was released for public preview and I must say that it is the best OCR I’ve ever used. UiPath OCR solved
a problem which I was having for almost over 2 years. However, since last 3~4 days it has stopped functioning with the below error message. Can someone please have a look and provide a resolution, would I be able to use it again, it was working brilliantly?

Hi @Jom4ick @luchovelez @VikasSteria

We updated the first post. Please check it out:

To get it to work, you now have to provide the CV API key which you can get from your Cloud Platform licensing tab.


Hi, just wanted to find out if anyone has this error, or how do i fix it…when I’m setting the cv screen scope…and am selecting the region, i always get a response “Response from server is not valid”…Getting the same error with all engines…Am i doing something incorrect…I’ve tried different engines as well


Hi @Avinash_Sewpersadh

Just check whether the provided API key is correct?

It is…triple checked that…could it be something like a firewall rule or something?..is there a way to view the server responses

I got this error once when I used it some time back, I’m just trying to recall how I resolved it… :thinking:

*Holding my breath :slightly_smiling_face: …Hope u remember…This thing is killing me…
im sure the request and response messages exist somewhere…being able to view them should be able to help with troubleshooting?..

…or if u have a better solution…

Thanks man

Do u think theres an issue on my platform? Im on beta 108

Hi… just to check… are you using the latest version of the activities?

" To get it to work, you now have to provide the CV API key which you can get from your Cloud Platform licensing tab."

What if we have on-premise installations of Orchestrator and CV and would still like to utilize UiPath’s screen OCR? We don’t have a cloud platform for our enterprise because we’re on-prem. Do we need to keep juggling community edition CV keys from cloud.uipath.com? Do they expire? Any additional info on this since almost two years ago? Thanks in advance.

Hi @Vaelaar, UiPath Screen OCR is now included in the Linux on-premise installation, so updating your server to the latest version should solve your issue. Alternatively, you can set the UseLocalServer property to True which enables the UiPath Scren OCR to run on your local machine (slower and with a slightly worse quality output, but it all depends on how heavy your needs are).

Hi, @Bogdan_Sultana! Thanks for the reply – are you referencing the latest version of… Orchestrator? Or CV? Just wondering which on-prem, Linux installation you are referencing and if it’s the same for any non-Linux installations.

Thanks again.

Hi, @Vaelaar, I was referencing CV. Only the Linux CV on-prem server has the UiPath Screen OCR now, but we’re working on releasing an identical Docker-based server for Windows in 22.4, so stay tuned; this will have all the features in the latest models, including table detection and Screen OCR.

Thank you Bogdan!
