ContractKen is a Microsoft Word add-in for lawyers that reviews and redlines contracts against playbooks and drafts from precedents. It costs $119 per user per month, with a 14-day guided free trial.
ContractKen is an AI add-in for Microsoft Word, designed for lawyers who review and draft contracts. Its site describes it as an assistant inside the document rather than a separate system, so reviewers stay in the tools they already use.
For review, it can work from a playbook you supply, from checklists, or from its own library of playbooks. If you have no playbook, a comprehensive mode looks for risks, ambiguities and missing clauses in contracts of any type or jurisdiction. Each flagged issue links to the place in the Word file, with a reason, a suggested way to reduce the risk and a redline you can apply in one click. For drafting, you can start from your own precedents, term sheets or letters of intent, and use a clause library that ships with more than 700 commercial clauses. Other tools check defined terms and key numbers and handle formatting.
The subscription is $119 per user per month with no minimum number of users, a 20 percent discount for annual billing and cancellation at any time with a pro-rated refund. The FAQ describes a free 14-day guided trial. A separate custom option is a proof of concept of eight to twelve weeks to build custom playbooks, clause libraries or workflow links, quoted on request.
The vendor describes a moderation layer meant to stop contract text reaching the AI model unprotected, and lists single sign-on, access controls and audit trails. No named security certification was read on the pages checked.
AI contract review is a first pass. Output can be incomplete or wrong, so a qualified lawyer should check any contract with real legal or financial consequences. This page does not give legal advice.
The FAQ describes a free, guided 14-day trial for all customers. There is no permanent free plan, and a credit card requirement was not stated.

| Can a general AI assistant replace it? | A general chatbot can explain a clause but does not mark up your Word file against a playbook. ContractKen does, and a lawyer still checks the result. |
