ClauseShield vs ThoughtRiver

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.

ThoughtRiver is an AI contract review tool for agreements reviewed before or after signing. Its Lexible LLM flags issues, obligations, and risks, while Playbooks check contracts against preset criteria and show which provisions are met or unmet. Teams can generate review output or redlines, and generative editing is designed to follow drafting style and negotiation guidelines. Contracts can be submitted by email, drag and drop, or the Word add-in; the platform works inside Outlook, Word, and Teams. Listed integrations include Microsoft 365, Power BI, HighQ, and iManage, and ThoughtRiver provides a public API following the OpenAPI Specification. It focuses on in-house teams and law firms processing over 200 agreements per year, while also supporting non-legal teams. ThoughtRiver lists no free plan and a 28-day trial. Monthly plans are 6.00 USD, 14.00 USD, and $49 a month; Professional starts at £15,000 a year and Enterprise at £30,000 a year.
