Vision transformers are good enough that you can use them alone even on cursive handwriting. I've had amazing results with Microsoft's models and have my own little piece of wrapper software I use to transcribe blog posts I write in my notebook.
Setting up my software online and monetizing it is next in the queue after my current side project. Although I haven't checked the model licenses.
And what the results were? And if not could you try and let us know what the results are.
