I was thinking ABBYY FineReader, but those, too. Instead of using VLMs or any sort of generative AI, they're build on good old-fashioned feature extraction and nearest neighbor classifiers such as the k-nearest neighbors algorithm. It's possible to build a working prototype of this technique using basic ML algorithms.
