In their own words
Plexus
Plexus is an AI-powered legal platform for in-house legal teams and the business groups they support. It combines contract and matter management with marketing and promotion compliance, reporting and legal AI. Contract workflows cover creation, negotiation, approvals, e-signatures, and reminders for renewals and milestones. Its AI can review and summarize contracts, identify risks or missing clauses against legal playbooks and policies, and answer document questions with context and suggested next steps. Matter Management tracks legal requests from intake through execution. Marketing Compliance helps teams review creative, while Promotion Compliance can generate campaign terms and permits. Word and Outlook add-ins connect contract and matter work to those applications; the platform also describes integrations with commonly used CRM systems, e-signature providers and document repositories. Plexus states that it is ISO 27001:2022 certified and GDPR compliant. It offers a free trial with full platform access and no credit card requirement, but gives no trial duration. Pricing is available on request and scales with legal team size.
