Looking for AI software that can generate documents for company based on the documents we feed "him"

Hi,

I’m looking for AI software that allows us to upload a large number of our existing Word/PDF documents (templates, past client documents, standard clauses, etc.) and then generate new documents based on those patterns.

What I’m NOT looking for is just a chatbot that answers questions about the documents. I need something that can:

• Learn from our document structure and wording
• Reuse our formatting and style
• Generate full new documents based on prompts and documents we feed it (ideally if you coul connect dropbox)
• Ideally integrate with Dropbox or similar cloud storage
• Export properly formatted Word documents

Support for non-English languages (in thi case Slovak) would be important as well.

Does anyone have experience with tools that can do this reliably?
