Chose
to add
Tesseract OCR
and to remove
Amazon Rekognition
at
()

AWS Rekognition has an OCR feature but can recognize only up to 50 words per image, which is a deal-breaker for us. (see my tweet).

Also, we discovered fantastic speed and quality improvements in the 4.x versions of Tesseract. Meanwhile, the quality of AWS Rekognition's OCR remains to be mediocre in comparison.

Worth mentioning that we run Tesseract in AWS Lambda via aws-lambda-tesseract library.
