Definely partners with Anthropic on Claude for the legal industry

Definely is partnering with Anthropic to bring specialist contract review tools into Claude for the legal industry.

Definely treats a contract as a structured object: clauses, definitions, cross-references, internal dependencies - providing repeatable and auditable results. From today, Definely tools are being made available through Anthropic’s Claude for the legal industry.

Example use cases:

• Verify contract drafts independently. Definely reviews through a separate, deterministic structural model checking for risk - those problematic clause mechanics and missing provisions that could impact a deal.
• Compare the draft against authoritative sources. Definely reviews against your firm's precedents and prior contract versions and surfaces every deviation with a traceable link back to the source it departs from.
• Proofread contracts. Definely proofreads the document structurally and gives the lawyer a list of issues to work through.
• Generate an issues list. Definely turns the changes in a marked-up contract into a structured issues list with columns for item, counterparty position, and client response.

"Expert judgement requires deep understanding when working with complex contracts. Definely provides essential review tools for lawyers to ensure every outcome is both reliable and rigorously accurate. Working with Anthropic as part of ‘Claude for the legal industry’ is a big step towards the future of contract review, and we’re excited to be at the forefront - meeting lawyers where they are increasingly working.”‍‍
