Prevail’s CheckMate Unifies AI and Depositions in Real-Time Revolution

SAN DIEGO, CA – February 23, 2026 – Legal technology provider Prevail today announced the launch of CheckMate, a platform poised to fundamentally alter the landscape of legal depositions by unifying real-time transcription, collaborative notetaking, and artificial intelligence analysis into a single, seamless workflow. The solution aims to solve one of the most persistent pain points for modern litigators: the fragmentation of tools and information during critical live testimony.

For years, attorneys have navigated a disjointed digital environment during depositions, arbitrations, and internal investigations. The process often involves juggling separate applications for live transcription feeds, another for personal and team notes, a third for accessing case files and exhibits, and often a fourth, entirely separate AI tool for post-proceeding analysis. This constant context-switching can distract attorneys from the witness, disrupt the flow of questioning, and delay the discovery of crucial insights.

Prevail’s CheckMate addresses this challenge head-on by creating an integrated ecosystem where live testimony, attorney notes, and exhibit materials are streamed directly into a law firm’s own large language model (LLM) in real time. This allows for immediate analysis, contradiction alerts, and the surfacing of related case materials without ever leaving the primary interface.

“CheckMate represents a fundamental shift in how legal teams experience depositions, arbitration hearings, and internal investigations,” said Rob Feigenbaum, CEO and co-founder of Prevail Legal, in the company's announcement. “Instead of managing five or six separate tools and reconstructing insights after the fact, attorneys can now stay fully present during testimony while their entire workflow operates seamlessly in the background.”

A Unified Front Against Fragmentation

The core value proposition of CheckMate is its consolidation of essential deposition functions. The platform is built on three integrated pillars designed to work in concert across all deposition formats, whether in-person, remote, or hybrid.

First is its Real-Time Transcription with Speaker Identification. Powered by Prevail’s proprietary court reporting technology, the platform delivers a live, searchable transcript with accurate tagging of who is speaking. This provides an immediate, reliable record that serves as the foundation for all subsequent analysis.

Second, the platform incorporates Collaborative Notetaking. This feature allows legal teams to communicate securely within the application, tag colleagues on specific points of testimony, and format notes for clarity. This eliminates the need for external chat programs or email chains, keeping the entire team aligned and focused on the live proceeding.

Finally, and most significantly, is the Integrated AI Analysis. CheckMate uses a secure API to stream the live transcript and associated notes directly to an organization’s LLM of choice, whether it's a proprietary model developed in-house or a commercial one. For clients without a dedicated legal LLM, the system can leverage Prevail’s native model. This vendor-agnostic approach allows firms to maintain control over their AI strategy and avoid vendor lock-in.

This integration means that as testimony unfolds, attorneys can query their own AI environment to instantly cross-reference statements against exhibits, identify potential contradictions with previous testimony, and receive strategic suggestions based on the full scope of case materials. This transforms AI from a post-mortem review tool into a live, strategic partner.

The Rise of the Real-Time AI Litigator

The introduction of real-time, integrated AI during depositions marks a significant evolution in legal practice, shifting the role of the attorney from a passive recorder of information to an active, data-assisted strategist. The ability to process and analyze information instantaneously provides a powerful tactical advantage.

This shift is already being recognized by early adopters. “Shook has integrated AI into our Complex Litigation Strategic Counseling Practice Group, including our work on early case assessment, case work up, and at trial,” noted Patrick Oot, a partner at Shook, Hardy & Bacon. “Part of that stack includes utilizing Prevail AI in live depositions. CheckMate connects the dots in real time. That fundamentally enhances how we prepare, question, and adjust strategy during testimony.”

The trend reflects a broader acceleration of AI adoption across the legal industry. Recent industry reports indicate a dramatic surge in AI use among legal professionals, with many firms moving beyond pilot programs to embed AI directly into their core workflows for tasks like document review and legal research. CheckMate pushes this trend into the high-stakes environment of live testimony, where the ability to adapt strategy on the fly can change the outcome of a case.

Securing the Digital Witness Stand

While the promise of AI is immense, its adoption in the legal sector has been tempered by profound concerns over data security and client confidentiality. With recent studies showing a high percentage of legal professionals are concerned about data privacy when using AI tools, a vendor's security posture has become a critical differentiator.

Prevail appears to have built CheckMate with these concerns at its core. The company emphasizes that its secure infrastructure ensures customer data remains within the client's own environment and is never used to train third-party AI models without explicit permission. This directly addresses the primary fear of data leakage, where confidential information entered into an AI model could be inadvertently exposed.

To back these claims, Prevail holds key industry certifications, including SOC 2 Type 2 and ISO 27001, which attest to its robust internal controls for security, confidentiality, and data processing integrity. The company also cites federal Authorizations to Operate (ATO), signaling its ability to meet the stringent security requirements of government agencies. By prioritizing a secure, client-controlled AI integration, Prevail is positioning itself not just as an innovator in workflow efficiency, but as a trusted partner in the responsible application of AI for sensitive legal matters.

Navigating a Competitive Legal Tech Landscape

Prevail is launching CheckMate into a dynamic and increasingly crowded legal technology market. Numerous companies offer powerful standalone solutions for transcription, such as Sonix and Rev, while others like Otter.ai provide real-time collaboration for meetings. In the broader AI and e-discovery space, established players like DISCO and Relativity offer sophisticated platforms for post-hoc analysis of large data sets.

Where CheckMate aims to carve its niche is not by competing with each of these tools individually, but by rendering the need for separate tools obsolete during a deposition. Its unique selling proposition lies in the seamless, real-time integration of transcription, collaboration, and AI analysis within a single, secure platform. The ability to plug directly into a firm's existing LLM, rather than forcing them onto a proprietary model, further distinguishes its strategy as both flexible and forward-thinking.

As law firms continue to invest heavily in both AI capabilities and operational efficiency, solutions that can bridge the gap between different technologies are becoming increasingly valuable. CheckMate, available as an add-on for new and existing Prevail customers, represents a significant step toward a future where technology empowers attorneys to focus entirely on their legal strategy, confident that the complex web of information management is being handled intelligently in the background.
