ClauseShield vs ContractKen

ClauseShield is a web-based contract analysis service for freelancers and independent contractors. It identifies eight clause types, including payment, termination, intellectual property ownership, liability, NDA, non-compete, and kill-fee clauses, then supplies risk scores, plain-English explanations, and suggested redlines. The maker says it checks more than 70 risk patterns and reports an F1 score of 0.9574 for its fine-tuned Legal-BERT model, trained on more than 40,000 legal clauses. It accepts PDF, DOCX, DOC, TXT, PNG, JPG, and JPEG files; scanned PDFs and images can be processed with OCR. Uploads are limited to 100 MB and 20 pages. Results can be exported as a redlined DOCX, PDF risk report, plain-text summary, or searchable six-sheet Excel workbook. The free plan covers three contracts per month. Pro costs $15 a month for 15 contracts, and Premium costs $29 a month for unlimited contracts. The maker describes the output as educational information, not tailored legal advice or a substitute for counsel.

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.
