It seems my language is not supported. Can it be added?
As the underlying algorithm matures, so does OwlOCR language support.
In MacOS Catalina only the English alphabet is supported, but when running on MacOS 11 Big Sur the language support has been expanded to include other major languages like French, German, Italian, Spanish, Portuguese and Chinese.
If your language has the same alphabet as one of these languages, your best option for now should be to disable Language Correction and select the closest match to that your language (as far as alphabet goes).
In the future language support will be expanded when it is possible to do so without compromising other OwlOCR priorities such as quality, performance, and secure, offline functionality.
