Go Legal AI 对比 CoCounsel (formerly Casetext)

Go Legal AI 是一个面向消费者的法律科技平台，在这里你可以提出法律问题、起草文件、编辑合同以及审查文书，全部集中在一个控制面板上。它结合了超过 5,000 个律师授权模板、法律人工智能工具，以及一个由 300 多位律师和 70 多个服务合作伙伴组成的网络，覆盖 150 多个司法管辖区。

工作流程是引导式的，而非开放式聊天。你选择一个模板或上传一个文件，回答一些有针对性的问题，平台会利用经过律师输入训练的人工智能建立或审查你的文书。智能审查通过交通灯分析、场景测试和行业标准的自定义评分，标识出潜在风险。

Go Legal AI 得到了牛津大学、LAWTECHUK、英国创新署（Innovate UK）和巴克莱银行（Barclays）的支持。它适合小企业主、房东、自由职业者以及需要负担得起的法律文件、快速合同审查或按需律师咨询，而无需雇佣完整的法律团队的消费者。

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.
