“One challenge before EvenUp was the time it took to put together a well-organized, easy-to-interpret demand with precise information—that includes medical codes and references to be able to quickly verify the information that we're providing.”
Lou Mattar
Attorney at William Mattar Law Offices
Their demand bottlenecks could delay moving cases forward and delivering much-needed settlements to their clients. Worse still, much of the team’s time was spent on administrative or repeatable work—like reconciling information from medical records—instead of building stronger cases, connecting with clients, or negotiating optimal settlements.
Practical, Secure Generative AI That’s Built for Law Firms
Tools like ChatGPT impressed Mattar early on, but the firm’s strict commitment to client confidentiality meant they couldn’t rely on public AI platforms for sensitive casework. That’s why
EvenUp’s Piai™ is so powerful—
HIPAA and SOC2 certified while saving Mattar significant time on every claim.
“Just having access to generative AI that is on a secure system is great. There's ChatGPT, but our firm is trying to not use it because it's not secure.”
Peter Mattar
Attorney at William Mattar Law Offices
Expert human review is an integral component of
Demands™. Piai™ combines expert human review with specialized AI models to outperform GPT-4 with 99% accuracy for each demand prior to sending it off to the firm.
This review enabled Mattar to just worry about all the final touches to make sure each demand is perfect when it goes out to the adjuster.
“What’s really exciting about EvenUp is that they’re taking it to the next level with AI. It’s hard to build this in-house, but EvenUp has world-class experts who can apply that technology. So you don't have to do it in-house.”

Express Demands™ is the first release of AI Drafts™, a brand new product suite that helps you draft any high-quality document in minutes at every stage of the case lifecycle. For example, Express Demands™ generates complete, customizable demand packages in just a few minutes using secure, generative AI—a massive leap forward for the Mattar team.
“Express Demands™ is going to be an awesome innovation. Getting a demand drafted in minutes will allow us to cut out any kind of delay... If it’s drafted right away, you can send it out right away.”

Since implementing EvenUp, the William Mattar team has seen measurable improvements across their case processes:
Less attorney and staff time spent on preparing demands
Faster turnaround from intake to demand submission
Greater accuracy and detail in demand packages
Improved client experience, as attorneys spend more time on personal connections
Lou explained that the AI-powered efficiency allows him to shift his time toward what matters most: his clients.
“It creates a time saving where you can get the information… in seconds. And then take that time savings and do something else that I can’t do—which is talk to your client and figure out how [their injury] is actually impacting their day-to-day life.”
Lou Mattar

He added, “What does it feel like when they’re trying to unload their car full of groceries? Or push a vacuum? Or pick up their toddler? Having those understandings can lead to a more well-rounded view of what this tragic accident has been.”
Even adjuster conversations have improved with the integration of EvenUp’s
Case Companion™, which uses generative AI to surface key answers in real time.
“Instead of saying, ‘Hold on, I’m going to look through these records,’ you can use Case Companion to ask a question and then give the adjuster an exact answer much quicker. That just makes things flow easier.”
