I want to be able to upload a document, like a PDF of TXT document, to Kagi Translate and have it returned in the language of choice I specify. It will allow me to read a full document in a new language without having to copy paste every portion.
I see a user uploading a document from a foreign language into Kagi Translate to be able to read it with all the existing images, but just with replaced text.
DeepL has this feature but does a write lock on documents if you don't have a paid account. It works for Microsoft documents in addition to PDF and TXT.
It might be wise to restrict this to paid accounts as documents can have more text than the current limit.
