Thomson Reuters and Supio AI partnership improves personal injury case outcomes

In personal injury (PI) law, every missed detail can cost your firm time, money, and justice for your clients. Attorneys face constant pressure to move cases faster, deliver stronger outcomes, and scale operations without sacrificing quality.

The new partnership between Thomson Reuters and Supio AI helps firms meet these demands with confidence.

Thomson Reuters brings trusted legal research, precedent expertise, and CoCounsel, an AI legal assistant that speeds up research, drafting, and document review. Supio specializes in case data and delivers AI tools built for PI and mass tort litigation. Together, they offer a complete solution that streamlines case management, automates workflows, and improves client communication.

Helping PI firms increase caseload capacity 

The U.S. PI market exceeds $61 billion and has a 2.5% compound annual growth rate (CAGR). Firms must manage growing caseloads, complex documentation, and tight deadlines. Supio’s AI-powered Document Intelligence™ platform helps firms turn medical records and case files into actionable insights, interactive chronologies, and strategic drafts.

Small and mid-sized firms often operate with lean teams and limited tech adoption. There are six ways Thomson Reuters and Supio AI help support these legal teams:

1. Smarter research and case insights: Thomson Reuters delivers trusted legal research and precedent analysis, while Supio AI helps attorneys quickly understand case data, timelines, and key facts.
2. Streamlined case management: Together, they automate routine tasks like document review, drafting, and data extraction, freeing up attorneys to focus on strategy and client outcomes.
3. Faster document workflows: CoCounsel speeds up legal drafting and review, and Supio automates intake and discovery for PI and mass tort cases.
4. Scalable operations: Firms can handle more cases efficiently without sacrificing quality, thanks to AI-powered tools that improve consistency and reduce manual work.
5. Better client communication: AI tools help track case progress and generate updates, making it easier to keep clients informed and engaged.
6. Security and reliability: Both platforms prioritize data privacy and compliance, ensuring sensitive case information stays protected.

Supio AI: Built for PI litigation 

Supio combines millions of PI data points with human expert review to deliver up to 97% citation precision and 96.6% extraction accuracy across six modalities (records, bills, voice, text, email, video). This unique approach effectively addresses the “hallucination” problem common in automated tools.

The platform leverages hundreds of AI models trained on PI and mass tort datasets, enabling structured medical reasoning and advanced document intelligence tuned for litigation. Its accuracy matches or exceeds human levels, which is critical for uncovering hidden injuries, building stronger client stories, and preparing solid cases.

Benefits of Supio include:

• Enhanced case preparation and efficiency: Supio’s CaseAware AI™ platform automates medical record review, organizes documents, and generates demand packages with high precision—reducing prep time from days to hours.
• Increased settlement values and case capacity: AI tools uncover critical evidence and ensure no injury is undervalued, leading to stronger demand packages and initial settlement offers—over 30% higher in some cases. Firms can also boost caseload capacity by up to 62% without increasing payroll.
• Leveling the playing field: Smaller plaintiff firms gain access to advanced technology that helps them compete more effectively against defense firms with deeper resources.

Supio’s strength lies in its deep understanding of medical data, which makes up 70–80% of PI documentation. The platform scans records to identify injuries that might otherwise go unnoticed.

Thomson Reuters: Legal technology you can trust

Thomson Reuters enhances Supio’s capabilities with its gold-standard legal research and AI-powered drafting tools. Through CoCounsel Legal, firms gain:

• Authoritative legal content and public records

Real-world impact: Use cases that prove value

Supio has processed over 27,000 cases to date, contributing to over $1 billion plus in settlements in the past year. Firms report measurable improvements in efficiency, accuracy, and outcomes:

• $24M jury verdict: An Oregon attorney used Supio to analyze trial transcripts in real time, defeating multiple directed verdict motions and securing a $24 million jury award.
• 4X settlement value: A firm used Supio’s demand drafting feature during mediation. The AI-generated medical chronology helped the mediator clearly understand the case, resulting in a proposal that quadrupled the defense’s original offer—from $95,000 to $400,000.
• 62% increase in caseload capacity: Firms handle significantly more cases without increasing headcount, thanks to Supio’s automation and AI-assisted workflows.
• Hidden injury detection: Supio flagged a delayed neurologist referral buried deep in a client’s medical records—an insight that changed the trajectory of the case. Its AI is trained in tens of thousands of cases to spot subtle patterns attorneys might miss, helping ensure no injury goes undetected.
• Improved client responsiveness: A Pennsylvania firm reduced the time it takes for attorneys to review files and contact clients from a week to just two days.

Looking ahead: From insights to autonomy

Supio has raised $91 million in funding, including a $25 million Series A (August 2024) and $60 million Series B (April 2025). Since its Series A funding, Supio’s Annual Recurring Revenue (ARR) has quadrupled, and its customer base now includes top PI and mass tort law firms nationwide.

The next phase of development aims to move beyond insights and toward autonomy, with three new product expansions announced at Supio Summit 2025. These include:

1. Supio Inbound™ for case intake
2. Case Engine™ with Instant Timelines, Demands, Case Signals™, and Economics™
3. Case Bench™ for litigation support

These innovations will further reduce administrative burdens and empower attorneys to focus on high-value legal work.
