When you use EarlyOffice AI, your request and the document text needed to answer it go through our server to the AI model provider (Anthropic or OpenAI; Google for hard requests — all USA). Our server does not store them. AI answers and edits can be wrong — check them before you use them. Legal templates and samples help you write; they are not legal advice.
