AI Contract Review & Redlining

About
LexCheck is an AI contract review and automated redlining company that enables legal teams to accelerate contract negotiation by automatically reviewing incoming contracts against a predefined legal playbook and generating redlines that reflect the organization's standard positions. Headquartered in Washington, DC, and having raised more than $19 million from investors including Union Square Ventures, LexCheck applies natural language processing and legal AI to identify deviations from preferred contract language and produce a first-pass redlined draft that attorneys can review and refine, compressing the time from contract receipt to first response from hours to minutes.\n\nLexCheck's playbook-driven approach is central to its value proposition — organizations define their standard positions, preferred language, and fallback positions for common contract provisions, and the AI applies these consistently across all incoming contracts regardless of volume. This systematizes contract negotiation in a way that maintains legal standards, reduces attorney-to-attorney variation, and allows less experienced legal staff to handle routine contract reviews with AI support. The platform supports NDAs, MSAs, SOWs, SaaS agreements, and other standard commercial contracts that legal teams review at high volumes.\n\nLexCheck competes with Luminance, Kira, and the redlining features of CLM platforms in the contract review automation space, while also competing with newer generative AI tools that law firms and in-house teams are experimenting with for contract review. LexCheck differentiates through its specific focus on automated redlining as a workflow deliverable — producing a tracked-changes Word document that integrates seamlessly into standard legal review processes — rather than providing insights or summaries that still require attorneys to create their own redlines.
