In their own words
ContractKen
ContractKen is contract review software delivered as a web product and extension, operating as an AI sidekick inside Microsoft Word. It supports drafting, reviewing and negotiating contracts, then turning agreements into operational business intelligence. During review, it identifies and explains problematic language against customer playbooks and can redline the wording. Drafting can use a customer’s precedents, termsheets and clause library, which contains more than 700 commercial clauses and accepts customer-owned clauses. The Word add-in also provides formatting and proofreading. Listed capabilities include clause extraction, risk identification, term comparison and OCR. Custom workflow integrations can include iManage, while enterprise single sign-on supports Azure AD, Okta and Google Workspace. ContractKen says customer documents, prompts and outputs are not used to train public or shared models. It states TLS 1.2-or-higher protection in transit and AES-256 at rest. Private deployment can place inference inside a customer Azure tenant or VPC. Pricing starts at 119 /user/mo billed annually.
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.
