Embed Word contract redlining in your product
Adeu gives your agents a native Word redlining engine that writes real OOXML tracked changes, not markdown diffs or plain text replacements. Test it below on a standard commercial NDA.
Ask a question about this contract or tell the agent what to revise. The assistant only answers from this document or proposes tracked changes to it.

Two things we maintain
Redlining Engine
Track changes for the LLM era
Projects a .docx into something an LLM can safely edit, blocks changes that would corrupt the file, and writes the result back as native Word tracked changes.
- Reads into CriticMarkup with a semantic appendix of defined terms and cross-references, so an agent works on structure instead of raw OOXML.
- Validates before it writes. Ambiguous text matches and invalid structural changes are blocked rather than applied.
- Writes native w:ins and w:del revisions. Layout, fonts, numbering, and margin comments survive the round trip.
Message Operator
EarlyA mailroom for agents
Connects Gmail and Microsoft Graph mailboxes and gives an agent a bounded surface to read, draft, and send. Packaged as a one-click bundle for Claude Desktop.
- Policy lives in config: allowed recipient domains, send rate limits, attachment size caps, and dry-run on by default.
- Every action lands in a JSONL ledger, and send intents are validated against a hash before anything leaves.
- State stays on local disk. Mailboxes are connected in chat, so there is no console step to hand to IT.

Adeu is infrastructure, not a platform. There is no workspace your users log into, and no review product competing with the one you are building. A full contract review platform could sit on top of an engine like this.
The engine is MIT and free, and that is not a trial. What teams shipping on it buy is the part a licence cannot give them: a maintenance commitment, a named counterparty, and a support agreement.
And if you would rather ship Adeu under your own name, with us behind it, that is an agreement we already make.
Ship it under your name
Legal tech vendors, CLM and procurement platforms, and enterprise tools teams put Adeu inside their own products. Three levels, each a real offer on its own.
Open source
MIT, free, forever
Embed the engine in a commercial product today, under your own brand. No agreement needed, and it is not a trial.
Supported
The engine you ship, with us behind it
A maintenance commitment, a named counterparty, and a support agreement behind the engine in your product.
White label
Adeu deeper in your product
The Brief, managed capabilities, and white-label terms, shaped per agreement. Tell us what you are building and we will put the right agreement together.
Frequently asked questions
Evaluate it, or just ask
Both repositories are open, and the benchmark runs on your machine. If it is faster to ask, the people who maintain the engine answer these.
