According to what I read in the documentation, it uses Tesseract underneath. I've used Tesseract v3 in the past and it was pain. Tesseract 4 uses LSTM neural net. How good is the performance and quality of the recognition nowadays in v4? Could anyone share his experience?

I use paperless-ngx for digitizing all my documents, it also uses Tesseract. The result is not perfect, but more than acceptable, if I scan at 600dpi

it's fine for simple use cases, but far inferior to the likes of GPT, Gemini or Mistral
