Mixus

Mixus is an AI agent platform for legal teams that works through email and Microsoft Word instead of a separate interface. An attorney forwards a matter to the agent by email, copies any reviewers, and receives work product back as reviewable files: redlines, drafts, analysis, extracted data and spreadsheet models. Attorneys then review and approve the returned file in Word or email, keeping a human in the loop on everything the agent produces. The core of the platform is playbooks. Upload prior deals and approved language and mixus turns them into review rules covering preferred language, fallback positions, required clauses and unacceptable terms, scoped by client, contract type or practice area. Attorneys can edit a playbook before the agent uses it. When reviewers accept, edit or dismiss suggestions, mixus proposes new rules from the repeated patterns, and attorneys approve them before they take effect. The site shows examples such as master services agreement and NDA redlines, Series A pro forma models and M&A waterfall analysis, and offers an Add to Word integration. It is aimed at law firms and in house legal departments that want firm level oversight and consistency across matters. Pricing is not published on the site. Access is through a demo request, so cost has to be obtained from the vendor directly.
