Our verdict on ThoughtRiver
ThoughtRiver is an AI contract review platform for in-house legal teams, law firms, and non-legal business teams. Its Lexible AI analyzes contracts for risks, obligations, and key clauses, while configurable playbooks help teams apply repeatable review criteria. Contracts can be submitted through the web application, email, drag and drop, or a Microsoft Word add-in. The platform also supports clause-level risk scoring, automatic redline generation, drafting options, collaboration, audit files, explainability, portfolio analytics, and reporting. It runs on web and Windows.
Pricing spans several published plans. The Starter, Pro, and Entreprise tiers are listed at $6, $14, and $49 per month, respectively, with highlights including task management, real-time collaboration, customizable dashboards, advanced analytics, resource allocation, and mobile accessibility. The Professional and Enterprise tiers are listed at £15,000 and £30,000 per year and include unlimited users, a private database instance, the Word add-in, Lexible Assistant, single sign-on, and dedicated customer success. A 28-day trial is available, but there is no free plan. Teams should review the plan structure closely, particularly when comparing the lower-priced monthly tiers with the annual enterprise offerings.
Its ecosystem fit is strongest for organizations working in Microsoft-centered environments or established legal information systems. Integrations include Microsoft 365, Power BI, HighQ, iManage, Microsoft Word, Microsoft Teams, and Microsoft Outlook. That combination supports document intake, reporting, collaboration, and work inside familiar Microsoft tools. ThoughtRiver suits teams that want a broad review workflow rather than a tool limited to clause comparison: its feature set extends from analysis and playbooks through redlining, issue collaboration, explainability, and portfolio reporting. Teams seeking a free product, a narrowly focused clause tool, or straightforward monthly plan comparison may prefer an alternative.
