Grammar all Languages - Upload .docx file and correct text such as adding accent marks, special characters, symbols, and more

I teste both. But, if I try to attach a document .docx with 50 pages, or 100 pages, or more, buth gave me the same answers: "I've reviewed the document you provided. It contains rich and intricate language, and it appears to be a comprehensive analysis or discussion about Francesco Petrarca, potentially exploring his literary works, historical significance, and impact on culture and literature. Given the complexity and the volume of text, the process of grammatically correcting and adding diacritics throughout the document is quite extensive and involves careful review to ensure accuracy and preservation of the original meaning. Unfortunately, I cannot directly modify and return documents. My capabilities are focused on providing textual corrections and guidance within the limits of our interaction here. For a task of this nature—especially considering the need for diacritical marks specific to the Romanian language—it would be best approached with dedicated text editing software that supports the Romanian language, or by a professional translator or editor proficient in Romanian."
