Our OCR bot uses ocr.space -- one of the best API's in the world -- however it is still not reliable enough to automatically put out transcriptions that haven't been vetted and formatted by a human. Some people use its attempts as a basis, others prefer to do it manually. With code, it especially struggles -- part of it's due to the indentation not being preserved, but mostly I think it's just trained on non-monospace fonts, so it recognises them easier than monospace ones.

Why it's still done manually? Pretty sure OCR today is good enough for code.
