CoCounsel (formerly Casetext) vs Legal Robot

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.

Legal Robot reads legal documents and flags risky language, unclear definitions, and style problems before you sign. Its Legal Simplifier turns dense legalese into plain English, and compliance helpers cover GDPR and DMCA requests. A Legal Graph Data layer lets you compare contract language against a large tagged corpus.

Most contract review tools send your files to a remote server. Legal Robot runs analysis on your device, encrypts the results with a key only you hold, and stores the ciphertext in your own cloud account. That local-first model targets teams who cannot upload sensitive agreements to a vendor cloud.

Legal Robot was trained on English-language contracts from the US, Canada, UK, and Australia under common law. The FAQ states it does not provide legal advice, only automated comparisons and linguistic statistics. New sign-ups currently show a Coming soon label on the homepage, so access may be limited even though the product pages remain live.

It fits small business owners, in-house counsel, and contract managers who need a first pass on agreements before involving an attorney. Support is email-only at [email protected], and the company lists a Vallejo, California address on its site.
