Wouldn't "Serverless OCR" mean something like running tesseract locally on your computer, rather than creating an AI framework and running it on a server?
Serverless means spinning compute resources up on demand in the cloud vs. running a server permanently.
Running it locally would typically be called “client(-)side”.
But this caught me for a bit as well. :-)
No, that would be "Running OCR locally..."
'Serverless' has become a term of art: https://en.wikipedia.org/wiki/Serverless_computing
