What ThoughtRiver is
ThoughtRiver is an AI contract review tool for agreements reviewed before or after signature. Its Lexible language model flags issues, obligations, and risks, while Playbooks compare contract terms against preset criteria and identify provisions as met or unmet. Teams can produce 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 also works inside Outlook, Word, and Teams. Listed integrations include Microsoft 365, Power BI, HighQ, and iManage, alongside a public API following the OpenAPI Specification. ThoughtRiver focuses on in-house teams and law firms processing over 200 agreements a year, while also supporting non-legal teams. There is no free plan, but a 28-day trial is listed.
