What is Mixus?

Mixus is the world's first AI agent platform that works entirely through email, designed specifically for legal professionals and enterprises. Attorneys send work to [email protected], CC reviewers, and receive redlines, drafts, analysis, and Excel models back as reviewable files—all with firm-level oversight and attorney-in-the-loop control.

The platform builds AI agents in plain English within seconds, automating multi-step legal workflows like contract redlines, diligence reviews, deal models (cap tables, M&A waterfalls), and data extraction. Mixus learns from your firm's past deals, approved language, and review decisions to generate custom playbooks that improve with each review. Key features include track changes with cited reasons for every change, live Excel formulas in returned models, and a Microsoft Word add-in for accepting/editing/dismissing suggestions without context switching.

Mixus is trusted by Am Law 10 firms and targets legal teams, businesses, and enterprises that need safe, verifiable AI deployment. The platform connects to Gmail, Google Drive, Salesforce, Jira, and 200+ other tools, supports real-time multiplayer AI collaboration, shared team memory (Spaces), scheduled automation, and enterprise-grade security including SOC 2 Type II, ISO 27001:2022, GDPR, HIPAA, TLS 1.3, AES-256 encryption, and customer-managed keys (BYOK).

Unlike fully autonomous agents, Mixus operates with colleague-in-the-loop oversight, enabling humans to approve critical actions before execution. This addresses the reliability gap in AI agents while democratizing access—no tech skills required. Users can build agents via email or chat, set human verifiers at specific workflow steps, and share agents across their organization.

Frequently asked questions about Mixus

What is mixus and how does it work?

Mixus is the world's first AI agent platform that works entirely through email. Send a message to [email protected] with your task in plain English, CC anyone who needs to review, and watch your agent handle complex workflows while you stay in control. The agent does the work (redlines, drafts, analysis, spreadsheets), attorneys approve it, and mixus learns from your decisions to improve future runs.

Who is mixus designed for?

Mixus is designed for attorneys and legal teams (starting with legal workflows), businesses, and enterprises that need safe, verifiable AI deployment. It's trusted by Am Law 10 firms and targets anyone who works in email and Word. The platform is simplified for everyone—no tech skills needed—and is perfect for teams of all sizes who want to automate tasks without sacrificing reliability.

How is mixus different from other AI agents?

Unlike fully autonomous agents that fail most work tasks, mixus operates with colleague-in-the-loop organizational oversight, enabling businesses to get AI efficiency without AI mistakes. Mixus meets customers where they are (email), builds agents in plain English in seconds, supports real-time multiplayer collaboration, offers shared team memory (Spaces), and enables agents to autonomously navigate organizational context—capabilities rare among today's agent platforms.

What legal workflows can mixus automate?

Mixus automates contract redlines (with track changes and cited reasons), diligence reviews, deal models (cap tables, M&A waterfalls, down rounds), data extraction, and any repeatable task your team handles often. Contract markups return with a cited reason for every change and a full issues list. Models return as real .xlsx files with live formulas ready in under 15 minutes, learning from your prior models.

How does the playbook system work?

Your past work generates the playbook. Instead of starting from scratch, mixus learns from your firm's existing workflows: prior deals, approved language, and review decisions. When you accept, edit, or dismiss decisions, mixus improves future runs. For example, after 14 prior reviews, mixus might propose a rule like 'In enterprise MSAs, always propose liability caps at ≥ 2× annual fees with a $2.5M floor' which a senior attorney approves.

What security and compliance certifications does mixus have?

Mixus has enterprise-grade security including SOC 2 Type II (annual), ISO 27001:2022, GDPR and HIPAA compliance, TLS 1.3 encryption in transit, AES-256 encryption at rest, customer-managed keys (BYOK), and zero data retention by model providers. Data is protected, encrypted, retained, and handled securely by model providers with firm-level oversight.

Can I integrate mixus with my existing tools?

Yes, mixus connects directly to Gmail, Google Drive, Salesforce, Jira, and 200+ external services and business applications. Agents can take real action inside your existing workflows, integrate with external services, and collaborate with other agents. You can configure authentication for external services and set up data access permissions during agent creation.

How does human oversight work in mixus?

Humans can be in the loop as much or as little as your business dictates. You add human verifiers by instructing at which step they should come to you for oversight—for example, directing an agent to send information to you for verification before sending it externally. Organizations can set company-wide rules (like ensuring external emails get checked by a human). Mixus enables colleague oversight but doesn't mandate it; if an agent has run a task hundreds of times successfully, you may trust it to continue autonomously.

What AI models does mixus use?

Mixus agents are built on a combination of Anthropic's Claude 4 and OpenAI's o3, with access to state-of-the-art models including GPT-4o, GPT-4o mini, Claude 3.5 Sonnet, o1-preview, and Gemini 1.5 Pro. The Free Plan includes access to GPT-4o mini, while the Pro Plan and above provide access to all models. Each model has different pricing rates for input and output tokens.

How do I get started with mixus?

Start with one legal workflow: pick a repeatable task like redlines, diligence, deal models, or data extraction. Build from examples using your past agreements or models to create the starting playbook. Your reviewers edit and approve it. Review real output—attorneys approve the work before it becomes a standard, and each review improves the next run. You can create agents by emailing instructions to [email protected] or via the chat function with written or vocal prompts. No credit card is required for the Free Plan.
