Features

Everything you need to review contracts faster

Four powerful tools. One sidebar. Stays inside your Word workflow.

Review & Redline

AI edits that appear as Track Changes

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.

  • Red strikethrough for removed text, green for additions
  • Accept or dismiss each suggestion one by one
  • Fully compatible with Litera Compare and iManage
  • Standard Word Track Changes — no extra software needed to review

Playbooks

Your firm's review checklist, automated

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.

  • NDA, SaaS, MSA, employment, and custom playbooks
  • Every suggestion traces back to a specific playbook rule
  • Shared across your organization — consistent reviews every time
  • Iterate and refine after the initial review
