Mixus puts legal AI agents where lawyers already work: email and Microsoft Word. That choice is more consequential than it sounds. Legal technology has a long record of failing on adoption rather than capability, because it asks lawyers to move work into a new platform, and the work stubbornly stays in email and Word regardless.
The agents handle redlines, contract analysis, drafting and models, and return them through the same channels. The governing constraint is attorney-in-the-loop control: the agent does the work and an attorney approves it, which is the only defensible arrangement given that professional responsibility for the output cannot be delegated to software.
A notable design detail is that the firm's own past work generates the playbook, so the agent applies the positions and language the practice already uses rather than generic drafting. That makes output more consistent with existing precedent, and makes the tool more valuable the longer a firm uses it.
