Legal AI is moving fast, and three names—Harvey, Legora, and now Lexi—are shaping how lawyers and in-house teams work. Each tackles the problem from a different angle: Harvey builds for the elite; Legora streamlines collaboration; and Lexi is redefining what a full-stack legal AI system can be.
Harvey: Power for the Top 1%
Harvey is built for the world’s largest law firms. Its focus is depth, not reach—LLM-powered legal research, document generation, and complex custom workflows for firms with thousands of lawyers.
It’s incredibly powerful, but also highly bespoke. Setting up Harvey means training it on firm data, integrating with internal systems, and customizing for enterprise-grade infrastructure. For BigLaw, that’s perfect. For smaller teams, it’s often out of reach.
Legora: Collaboration for Growing Teams
Legora takes a more accessible approach. It integrates directly into Word and Outlook, making it easy for legal professionals to review, draft, and manage contracts collaboratively. Its clean UI and workflow automation tools make it appealing for mid-sized firms and corporate legal departments that want smarter document handling without rebuilding their tech stack.
Still, Legora—like most legal-AI tools—sits in a single lane. It’s great at document review and due-diligence tasks, but it’s not designed to automate the entire legal lifecycle.
Where Lexi Comes In
That’s where Lexi steps in.
If Harvey is power for the elite and Legora is collaboration for the organized, Lexi is the full-stack legal AI for everyone else—especially smaller law firms and in-house legal teams that need speed, scale, and automation without the enterprise overhead.
Lexi isn’t just a point tool; it’s a platform.
It covers the entire journey:
Client intake and triage
Legal research and precedent discovery
Drafting and template automation
Case chronology and task management
Real-time analytics and reporting
Behind the scenes, Lexi runs on agentic AI workflows—specialized legal AI agents that don’t just answer prompts but act autonomously, completing multi-step legal tasks from start to finish.
Why Full-Stack Matters
Point tools (like contract review or research assistants) help with fragments of legal work. But today’s lawyers don’t need fragments—they need flow. Lexi’s “full-stack” design means every workflow is connected. Intake data feeds into drafting. Drafts sync with case timelines. Chronologies auto-generate briefs.
The result: no copy-pasting, no tool-switching, no lost context.
Built for the 99%
Where Harvey’s infrastructure suits the top 1% of firms, and Legora targets mid-tier collaboration, Lexi is built for the 99% of legal professionals the in-house counsel, boutique partners, and legal operations teams that want enterprise-grade capability in a simple, secure, scalable platform.
It’s not just a co-pilot; it’s your AI associate.
Final Thoughts
Legal AI is no longer about having a smarter assistant—it’s about having a connected, autonomous system that scales your entire practice.
Harvey made AI usable for global firms.
Legora made it collaborative for growing teams.
Lexi makes it full-stack and accessible for everyone.
The future of legal work won’t be defined by tools, it’ll be defined by systems that think, act, and deliver like your best associate. That’s Lexi.
