In their own words

BlackBoiler

BlackBoiler reviews contracts in Microsoft Word by applying an organization’s playbook, previous redlines, approved wording, and examples. It creates first-pass tracked changes and comments; reviewers then accept, modify, reject, escalate, or negotiate each suggestion. Veris provides conversational access to playbooks and contract language within Word. The service covers recurring agreements such as NDAs, service agreements, and subcontracts, plus construction prime contracts, subcontracts, and professional services agreements using AIA, ConsensusDocs, and EJCDC forms. BlackBoiler is aimed at in-house legal teams, law firms, contract managers, and construction legal, commercial, procurement, and project teams. It concentrates on pre-execution review and redlining, while an existing CLM can handle intake, approvals, signatures, and the broader lifecycle. Platforms are web and API. Starter costs $1,250/user/year, Pro costs $3,000/user/year, Enterprise pricing is custom, and a seven-day trial requires a credit card.

Definely

Definely is a suite of AI tools for lawyers creating, drafting, and reviewing complex contracts in Word. Read surfaces defined terms and cross-references for editing in context, and can list defined, undefined, and unused terms in a Definitions Report. Proof flags incomplete information, inconsistent formatting, and spacing issues. Cascade identifies clauses, definitions, and references that may be affected by contract changes. Enhance lets users ask questions about contracts in natural language and cites relevant clauses and definitions. Vault connects to a document management system to search for and reuse precedent clauses and provisions. Workflow integrations shown include Microsoft Word, iManage, NetDocuments, and SharePoint. Definely runs on macOS, Windows, and the web, and supports Microsoft Word and PDF. Draft and Proof currently work in English and Swedish; the maker says other document languages are not currently supported. Pricing is available on request, and Mac users can start a free 14-day trial. The company offers a Help Center, while enterprise customers may receive dedicated support. Its Trust Centre lists security and compliance items including ISO/IEC 27001:2022, SOC 2 Type 2, GDPR, ISO/IEC 42001:2023, and Cyber Essentials.
