:Harvey: Accelerates Enterprise AI With Agent‑Powered Platform and Microsoft 365 Copilot

The majority of legal work is done inside Microsoft 365. While Copilot has transformed everyday productivity, the rise of AI agents has introduced fragmented, isolated systems that force lawyers to manually stitch together context across tools that weren’t designed for legal work. Complex legal work requires specialized intelligence, precedent-aware context, and deeper reasoning.

That’s why Harvey is expanding its collaboration with Microsoft, a leader in the AI space, by building an integration with Microsoft 365 Copilot. By embedding agentic legal intelligence into the tools legal teams already use, Harvey enables lawyers to move from quick questions to deep analysis and execution, without disrupting their workflow. This integration brings together the best of both worlds: Microsoft’s productivity, enhanced with Harvey’s legal-specific AI.

Specialized Legal Intelligence in Your Workflow

Legal teams lose meaningful time and momentum switching between tools just to assemble the context needed to do their work. In a LegalLeaders study of more than 300 in-house legal professionals across the US, Australia, and the UK, nearly 70% reported spending over an hour each day moving between systems to piece together information, documents, and priorities.

With Harvey integrated into Microsoft 365 Copilot, teams can access legal intelligence directly in their workflow.

Start With Answers You Can Trust

Legal teams can access Harvey’s legal intelligence in Copilot. Simply @Harvey in Copilot or select the Harvey agent from the sidebar to ask general legal questions, research issues, analyze documents, or pull in content from the user’s vaults.

Go Deeper When the Work Demands it

When a question turns into a larger task, click "View in Harvey" to move the thread to Harvey for deeper analysis, advanced reasoning, and refining work product — whether you're preparing a memo, building an argument, or developing a negotiation strategy.

Stay in Flow Across Legal Work

From quick research to full document analysis and back to business communication, Harvey and Copilot work together to support legal teams at every stage, within a single workflow.

Continue Your Work in Word

The same workflow that starts in Copilot can continue seamlessly in Word. When quick questions evolve into deeper document work, Agentic on Word, a powerful agent in the Harvey for Word Add-In, brings more intelligent planning, reasoning, and faster execution to complex legal documents.

The iteration overhead is real: legal teams spend hours refining redlines before they're client-ready. Agentic Word solves this fundamental problem and enables teams to:

• Handle complex legal work: Analyze lengthy, high-stakes agreements with improved reliability and fewer errors.
• Produce higher-quality edits: Generate trusted redlines with deeper reasoning that better reflect legal intent and negotiation strategy.
• Work without mode switching: Complete multi-step legal tasks without managing modes. Harvey plans the right action based on the task at hand, eliminating the need to toggle between Ask, Edit, and Draft modes.

An End-to-End Legal Workflow in Practice

Together, Harvey in Microsoft 365 Copilot and Agentic Word support legal work from first question to final execution — all within a unified workspace that thinks, reasons, and works where you do.

Consider a common scenario. You're in-house counsel negotiating a $50M senior secured credit facility with a bank. You receive a 247-page credit agreement and need to align it with company standards, get it approved by your CFO, and respond within 48 hours.

Traditionally, this kind of review would take 15–20 hours and involve jumping between systems, reassembling context, and managing risk under tight deadlines.

With Harvey in Copilot and Agentic Word combined, the workflow stays connected. Here’s what this looks like in practice:

1. Use Harvey's intelligence within Copilot

Upload the agreement in Copilot, and click on the Harvey agent in the sidebar to analyze current market terms for tech-sector credit facilities. For deeper analysis, click on “View in Harvey” to continue your work there.

2. Access your work product while in Copilot

As the negotiation progresses, Copilot helps you pull precedent deals and negotiation positions from Vault, analyze counterparty responses to identify leverage points, and identify key terms from prior successful negotiations.

Once you’re done with your analysis, you can then move to Microsoft Word to draft, edit, and review documents.

3. Analyze and execute in Word with agentic depth

Harvey’s Agentic Word reviews the full agreement against precedents in one pass, flags critical issues, executes strategic redlines with deep reasoning, and generates side-by-side comparisons.

The result: a redlined agreement in minutes, plus clear stakeholder communication and complete transaction documentation, all within Microsoft 365.

Legal Intelligence That Works Where You Work

Legal work doesn’t need more tools. It needs intelligence that operates inside existing workflows, with the depth and judgment legal work requires.

Harvey’s integration with Microsoft 365 Copilot, paired with advanced agentic capabilities in Word, represents a fundamental shift: AI that adapts to how lawyers work, not the other way around. From quick questions in Copilot to sophisticated document analysis in Word, Harvey delivers legal expertise at every level of the workflow.
