The Platform

Your past work generates
the playbook.

Instead of starting from scratch, mixus learns from the way your firm already works: prior deals, approved language, and review decisions.

01 / Playbooks

Playbooks capture how your firm reviews work.

Each playbook can be scoped by client, contract type, or practice area. It stores preferred language, fallback positions, terms to flag, and the reviewer approvals behind them.

PlaybookMSA v3.1 · Lumengrid

§ 4.2 Limitation of Liability

Starting position2× annual fees, with $2.5M floor for enterprise customers.

Fallback1.5× annual fees with $1.5M floor; escalate to senior reviewer if counterparty refuses.

UnacceptableAny cap below $1M · mutual exclusions of indirect damages without carve-outs.

02 / Review decisions

Every review improves
the next run.

When attorneys accept, edit, or dismiss suggestions, mixus learns the firm's preferred position. Repeated patterns become proposed rules for attorneys to review and approve.
