Adeu acts as a "Virtual DOM" for Microsoft Word documents. It provides a two-way abstraction layer that lets AI agents freely edit DOCX files (Track Changes, Comments, Accept/Reject) via a lightweight Markdown proxy. This allows LLMs to negotiate and redline contracts without destroying the underlying OOXML formatting, images, or tables. On Windows, it natively connects to the active MS Word application to perform edits live on the canvas.
