About mixus
mixus is a legal AI agent platform designed for attorneys and law firms. It works through the tools lawyers already use, especially email and Microsoft Word, to return redlines, drafts, analysis, issues lists, and deal models as reviewable work product.
The platform is built around attorney-in-the-loop workflows, firm-level oversight, and playbooks learned from prior work and reviewer decisions. mixus is especially relevant for legal teams that want AI assistance for contract redlines, diligence, deal modeling, drafting, and document review while preserving professional judgment and review controls.
Key Features
Email-native workflows : Send work by email, CC reviewers, and receive output back in the same working style attorneys already use.
AI Redline Review : Return contract markups with track changes, cited reasons, and an issues list.
Deal modeling : Generate cap tables, M&A waterfalls, down rounds, and bespoke structures as editable Excel files with live formulas.
Word Add-in : Bring mixus into Microsoft Word so attorneys can accept, edit, or dismiss suggestions without switching tools.
Playbooks : Capture preferred positions, fallback language, unacceptable terms, and review decisions by client, contract type, or practice area.
Reviewer learning : Accepted, edited, and dismissed suggestions improve future runs and can become proposed rules.
Firm oversight : Attorneys approve work before it becomes standard, keeping legal judgment in control.
Enterprise trust : Site references SOC 2 Type II, ISO 27001, GDPR, HIPAA, encryption, BYOK, and zero data retention by model providers.
