AI redlining, playbook-driven review, and document chat — all as a native sidebar in Microsoft Word. No switching apps.
Takes under 2 minutes. Included with all mixus plans.

Features
Four powerful tools. One sidebar. Stays inside your Word workflow.
Review & Redline
Ask mixus to redline your document and every suggestion appears as a native Microsoft Word Track Change — attributed to 'mixus AI'. Review, accept, or dismiss each one individually, or accept all with one click.

Playbooks
Playbooks turn your standard review guidelines into one-tap automated reviews. Run your NDA playbook, SaaS agreement review, or any custom playbook you've built — and get structured Track Changes back instantly.

Prompts
The Prompt Library gives you one-tap access to the instructions you use most. mixus also reads your document and suggests relevant prompts automatically — so you always know what to tackle next.

Connected to mixus
mixus works across email and Word — pick up wherever it's most convenient, with full context preserved throughout.
Forward a contract to your mixus agent email address with instructions. The AI reviews it and sends back a redlined draft with tracked changes.
Your inbox gets back a .docx with AI-suggested changes as standard Track Changes. Open it in Word — your mixus sidebar is ready to continue.
With the plugin open, run further playbooks, ask follow-up questions, or trigger a second-pass redline — all with the document already in front of you.

Mixus vs Claude
You are used to Track Changes and comments as the system of record. Document features in general-purpose AI continue to expand (including Microsoft-365–adjacent options for some Claude customers), but firm-wide review with playbooks and analytics is still a packaging problem. Mixus meets lawyers in Word with org-backed redlines—not a one-off sidebar experiment.
Word where lawyers already live
Review inside the document, not only beside it.
Playbooks and review discipline
Institutional standards, not one-off prompts.
Spreadsheets and memos as deliverables
Working Excel outputs, not only chat text.
Admin, monitoring, and org controls
Visibility for innovation and risk teams alike.
Includes narrative context, a capability matrix, and primary sources with a visible last-updated date.
Install the add-in, open any Word document, and start reviewing with AI. Included with all mixus plans.
