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.
LegalSifter
LegalSifter’s ReviewPro applies a company’s legal and risk positions to contracts and creates tracked-change drafts. Edits can include plain-English explanations and optional comments for the counterparty. ReviewPro Assistant can draft terms and make custom edits through a conversational interface. More than 100 standard playbooks are included, and users can build their own from templates, past redlines, or policy documents. Add-ins bring the product into Microsoft Word and Google Docs. The wider contract workflow includes a searchable repository, intake, ticketing, Kanban, approval workflows, obligation tracking, renewal alerts, AI contract review, native e-signature, and a workflow builder. LegalSifter says ReviewPro is hosted on AWS and is SOC 2 Type II and HIPAA compliant. The product is aimed at CFOs, COOs, and operations leads responsible for contracts; legal training is not required. Standard implementation and onboarding are included. The web product has paid annual plans, with listed prices ranging from $2,750 a year to $40,000 a year. A free trial runs for seven days and covers up to 20 contracts; it requires a company email and is limited to the US, Canada, and the European Union.
