AI.Law 对比 CoCounsel (formerly Casetext)

AI.Law 是一个专为民事诉讼律师打造的诉讼操作系统，旨在帮助他们在不增加人手的情况下推动案件进展。其核心是“战场屋”（War Room），一个案件地图，可以在一个连贯的视图中跟踪索赔、辩护、法律要素、证据、漏洞、截止日期和下一步行动。

该平台包括超过60个工具，用于起诉书起草、证据发现、动议、证词分析、医疗时间线和案件管理。AI输出引用上传的文件，并且案件法引用已通过CourtListener验证。公司持有美国专利号12,461,932，并获得SOC 2 Type II认证。

AI.Law 由Troy Doucet律师建立，他曾创立一家处理超过2200个案件的诉讼实践。其目标用户包括原告和辩护律师事务所、单人审判律师、律师助理，以及管理繁重案件负载、 contingency 案件或固定费用诉讼的律师团队。

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.
