Redline contracts the way
your firm would
mixus reads, marks up, and returns your contracts with native Word track changes — applying your playbook rules and getting sharper with every review.
Works in chat, by email, and inside Microsoft Word.
What redline handles
More than contract negotiation
Contract redline
NDAs, MSAs, term sheets, vendor agreements — marked up with native Word track changes and a comment explaining every edit.
Template & form fill
Fill in blanks, bracketed placeholders, and underscore fields across standard templates — consistently and at scale.
Clean document output
Accept all existing track changes and produce a normalized, clean .docx — useful for finalizing counterparty redlines before signature.
How it works
Your standards, applied every time
Three systems that make every redline consistent, traceable, and better than the last.
Playbooks
Your positions, applied automatically
Assign a Playbook to a Space and every redline follows it — standard clauses required, unacceptable language flagged, fallback positions used when yours can't land.
- Every tracked change cites the Playbook rule that triggered it
- Unacceptable language flagged even when it can't be removed unilaterally
- Required clauses added if missing from the contract
- Reference a Playbook explicitly or let mixus detect the right one
AI Learnings
Every review makes the next one better
Dismissals, edited suggestions, and reviewer notes become learning signals. Those signals compact into rules. Rules inject into every future run — automatically.
- Accept/dismiss decisions saved per change, per reviewer
- Only disagreements and edits become learning signals — not noise
- Rules synthesized with confidence scores from reviewer feedback
- Rules with ≥ 30% confidence inject into every future redline
Institutional Memory
Standards that outlast your team
Playbooks, learned rules, and review history live in Memory. When attorneys leave, the standard doesn't leave with them.
- Playbook library versioned with full history
- Consistent output regardless of who runs the review
- Every edit traceable to a rule or learned signal
- Firm positions embedded permanently — not in anyone's head
How to use it
Three ways to redline
Use whichever fits your workflow. All three use the same AI and the same standards.
Chat
Upload a .docx, describe what you need, and get the redlined file back in minutes.
Forward the contract to agent@mixus.com with your instructions. The redlined .docx comes back to your inbox.
Word plugin
Redline without leaving Word. Suggestions appear as track changes you can accept or dismiss in place.
Email workflow
Forward it. Get it back redlined.
No app required. Attach the contract, add your instructions, and the redlined .docx arrives in your inbox.
Please redline the attached NDA in favor of the disclosing party. Apply standard protective language and flag any unusual carve-outs.

Mixus vs Claude
How this differs from a general-purpose Claude chat
You are used to associates following your playbook and a partner QC loop—not improvising from a blank thread. Claude is strong as an assistant, but the firm still has to engineer prompts, move files, and police consistency. Mixus is built around institutional review, training signals, and org visibility so the workflow is ready out of the box.
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.
