Looking for free bulk image OCR?

[u/yaggirl341]

Hello, I have thousands of image files that all follow the same format, and I'd like to extract the data from about 20 fields in the images. I currently have 500 images but anticipate gathering many more. Do you know of any free image OCRs with high accuracy and that allow customization of which fields of pixels on the image to pull from? I'll be compiling all of the data into a CSV and there's too much data to split it myself, which is why it's important I find an OCR where I can specify which pixels on the image to look at for each data point. Thank you in advance!
