Legora (formerly Leya) 对比 CoCounsel (formerly Casetext)

Legora是一款为律师事务所和内部团队打造的协作式人工智能。它运行在Legora aOS上，这是一种具有代理功能的操作系统，能够将法律研究、文件处理、沟通与客户交付集成于一体。律师在处理高风险决策时保持判断力，而平台则负责重复的审查、起草与研究工作。

该产品套件包括用于端到端法律工作的Legora Agent、具备管辖区感知的法律研究工具、用于大量文件集的Tabular Review，以及用于监管变化追踪的Monitors。律师可以通过Word和Outlook插件、网页版编辑器、移动应用以及面向客户的门户进行操作。

Legora支持从并购、诉讼到税务、银行和保险等多个法律专业领域。工作流程工具将事务所的操作手册和判例编码进去，使得机构知识能在每个案件中得以传承。企业安全功能包括伦理墙、审计追踪，以及SOC 2 Type II、ISO 27001、ISO 42001、GDPR和HIPAA等认证。

公司报告在30多个市场中拥有超980个客户。其访问权限通过演示为基础的企业销售模式提供，而非自助注册。

CoCounsel is a legal research and drafting assistant now owned by Thomson Reuters after acquiring Casetext in 2023 for $650 million. It runs case law research, document review, contract analysis, and guided drafting grounded in Westlaw and Practical Law rather than the open web.

Standalone legal chatbots pull from generic training data. CoCounsel ties every answer to Thomson Reuters authority, which means citations trace back to Westlaw primary law and Practical Law guidance. The 2026 next-generation release adds Workspaces for matter-specific context, Brief Builder for agentic motion drafting, and a firm-intelligence layer for encoding internal expertise.

Litigation teams, transactional lawyers, and in-house counsel at firms already paying for Westlaw use it to cut research time and review contracts at scale. Pricing is sales-led with no public rate card, and the tool delivers the most value when bundled with an existing Westlaw subscription.
