Beyond Legacy Legal AI
Four Skills. One Resident Agent.
The Only AI Built to Live Inside Your Firm’s Firewall.
Legacy tools fragment drafting, research, and review. Arivu’s Resident Agent executes them as a single, matter-aware workflow operating natively inside your Microsoft 365 tenant.
Most Legal AI requires you to move your data to their “Vault.” Arivu.Legal flips the script. We bring the intelligence to your data. The Resident Agent is a secure, containerized intelligence layer that operates natively within your Microsoft 365 tenant.
01 Intelligent Research
Indexing Prior Matters
The agent reasons over legal concepts—not keywords—scanning your SharePoint corpus to surface how the firm addressed comparable issues. It ensures continuous matter-aware indexing and retrieval of institutional knowledge.
• Reduces manual search effort for associates
• Accelerates insight-driven decision making
“Agent, find our three most recent memos on GDPR compliance in cross-border M&A.”
02 Proactive Review
Scanning for Deviations
Incoming documents are reviewed against playbooks, highlighting critical deviations and risk exposures before manual review begins. It provides early visibility for partners and counsel
• Continuous monitoring of critical clauses
• Supports compliance with internal risk policies
“Agent, compare this indemnity clause to our standard corporate position.”
03 Contextual Drafting
Applying Firm Precedent
Drafting is guided by matter context and institutional precedent, ensuring consistency with the firm’s negotiated positions. The agent suggests clauses automatically based on matter type and jurisdiction.
• Ensures language consistency across documents
• Reduces drafting errors and repetitive tasks
“Agent, insert a limitation of liability clause for a mid-market SaaS transaction.”
04 Executive Summarization
Monitoring Obligations
Long-form agreements are distilled into actionable risks, obligations, and timelines suitable for partner and client-level consumption. It identifies critical dates and exposure points for stakeholders.
• Prioritizes actionable insights for stakeholders
• Supports informed strategic decision-making
“Agent, summarize the top five commercial risks in this 200-page lease.”
What Makes an Agent “Resident”?
Traditional AI requires copy-paste workflows. Arivu’s Resident Agent operates directly inside Word and Outlook, continuously reasoning over SharePoint content already authorized within your tenant.
01. In-Situ Intelligence (The “Anti-Vault”)
Unlike legacy systems that “ingest” data into external clouds, the Resident Agent executes in-situ.
- Zero-Export: Your high-stakes M&A drafts and litigation memos never leave your tenant boundary.
- Stateless Processing: The Agent reasons over your data in private, temporary sessions that are wiped immediately after the task is done.
02. Continuous Matter-Awareness
The Agent doesn’t just “see” the document you have open. It “understands” the entire SharePoint folder.
- Cross-File Context: While you draft in Word, the Agent is aware of the related emails in Outlook and the precedents in your archive.
- Automatic Synthesis: It connects the dots between a Master Agreement and its 50 sub-schedules without you having to “upload” them one by one.
03. Identity-First Security (Entra ID Native)
The Resident Agent is the only legal AI that respects your existing security protocols in real-time.
- Permission Mirroring: If an Associate doesn’t have permission to see a folder in SharePoint, the Resident Agent won’t see it either. No manual permission syncing required.
Full Auditability: Every action the Agent takes is logged directly in your Microsoft Unified Audit Log, making it the most “referencable” AI for compliance-heavy firms.
