> Regular handwriting there are many.

Please share. I am out of the loop and my searches have not pointed me to the state of the art, which has seen major steps forward in the past 3 or 4 years but most of it seems to be closed or attached to larger AI products.

Is it even still called OCR?

Totally not what you asked, but making an OCR model is a learning exercise for AI research students. Using the Kaggle-hosted dataset https://www.kaggle.com/datasets/landlord/handwriting-recogni... and a tutorial, eg https://pyimagesearch.com/2020/08/17/ocr-with-keras-tensorfl... you can follow along and train your own OCR model!

The best open source OCR model for handwriting in my experience is surya-v2 or nougat, really depends on the docs which is better, each got about 90% accuracy (cosine similarity) in my tests. I have not tried Deepseek-OCR, but mean to at some point.
