adeu 0.4.0

Automated DOCX Redlining Engine

Adeu: AI Redlining Engine

Adeu allows AI Agents and LLMs to "Track Changes" in Microsoft Word documents.

Most LLMs output raw text or Markdown. Professionals need w:ins (insertions) and w:del (deletions) to review changes inside Word. adeu lib shows a Word document in an LLM and human understandable textual format and reflects changes made to it to the actual word document.

It creates a "Virtual DOM" of your document, letting AI apply surgical edits without breaking your formatting, numbering, or headers.

Installation

Adeu is available on PyPI.

pip install adeu

Ways to Use Adeu

1. As MCP Server (No Code Required)

If you use an agentic system such as Claude Desktop, you can connect Adeu directly. This lets you handle contracts in Claude and say: "Change the Governing Law to Delaware and generate me the redline."

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "adeu": {
      "command": "uvx",
      "args": ["adeu", "adeu-server"]
    }
  }
}

(Requires uv installed on your machine)

2. For "Vibe Coding" & Python Scripts

Building your own Agentic AI tool in Cursor, Replit, or Windsurf: Adeu is the engine that handles the document manipulation for you.

from adeu import RedlineEngine, DocumentEdit
from io import BytesIO

# 1. Load your contract
with open("NDA.docx", "rb") as f:
    doc_stream = BytesIO(f.read())

# 2. Define the change (Usually this comes from your LLM response)
edit = DocumentEdit(
    target_text="State of New York",
    new_text="State of Delaware",
    comment="Changed governing law to neutral jurisdiction."
)

# 3. Apply the Redline
engine = RedlineEngine(doc_stream, author="AI Associate")
engine.apply_edits([edit])

# 4. Save
with open("NDA_Redlined.docx", "wb") as f:
    f.write(engine.save_to_stream().getvalue())

3. The CLI

Quickly extract text or apply patches from your terminal.

# Compare two docs and see a summary
adeu diff v1.docx v2.docx

# Apply a JSON list of edits to a doc
adeu apply agreement.docx edits.json

Why Adeu?

• Native Redlines: Generates real Microsoft Word Track Changes. You can "Accept" or "Reject" them in Word.
• Format Safe: Adeu preserves your complex numbering, headers, footers, and images. It only touches the text you change.
• Native Comments: Supports adding comments (Review Pane) linked to specific text ranges.
• Intelligent Mapping: Handles the messy internal XML of Word documents (e.g., when "Contract" is split into ["Con", "tract"] by spellcheck).
