The interface you are using is designed for text-based conversations and does not support direct document editing or updating. This limitation is inherent to the platform, which operates as a conversational AI without the capability to manage or store documents persistently. Each interaction is independent, meaning the AI can only process information provided within the current session and cannot retain or modify documents over time.

For updating documents, you should use dedicated document editing software such as Microsoft Word, Google Docs, or other document management systems. These tools are specifically designed for creating, editing, and managing documents, allowing you to make changes and save them for future use. Once your document is updated, you can share the relevant information here if you need further assistance or have specific questions related to the content.
