What AI Does BigLaw Use for Legal Research?
The BigLaw Reality Check:
BigLaw firms don't mess around with unproven technology. When the OpusLaw Team first pitched Carta AI to Am Law 100 firms, they had one question: "Can we stake our reputation on this?" The answer had to be yes. That's why 89% of these firms chose us—not because we're cheaper or faster, but because we're the only AI they can trust when $500M deals are on the line.
Why BigLaw Demands More Than Generic AI
BigLaw operates in a different stratosphere. When a single mistake can cost millions and reputations are built over decades, the AI you choose isn't just a tool—it's a strategic imperative.
BigLaw Adoption Metrics
The numbers tell a compelling story. When the world's most prestigious law firms make technology decisions, they choose based on results, not marketing.

OpusLaw Team's BigLaw Insights
After working with dozens of Am Law 100 firms, the OpusLaw Team has learned what really drives BigLaw technology decisions. Here are his key observations.
The BigLaw Security Obsession
"The first question every BigLaw firm asks isn't about features—it's about security. When the OpusLaw Team pitched Carta AI to managing partners, they wanted to know: 'Can we stake our $6B reputation on this?' That's when I realized BigLaw doesn't buy AI—they buy insurance against being outmaneuvered."
"Attorney validation wasn't a nice-to-have for these firms—it was non-negotiable. They needed AI they could trust completely, not AI they had to fact-check constantly."

The M&A Speed Advantage
"M&A partners were our toughest critics. They needed AI that could analyze international contracts in multiple languages simultaneously—something no other platform could do. When the OpusLaw Team showed them Carta AI processing German, Japanese, and English contracts in parallel, that's when they knew we were different."
"The 40% faster deal closure wasn't just about speed—it was about accuracy across languages and jurisdictions."

The Enterprise Architecture Challenge
"Global law firm CTOs have seen every AI platform fail at scale. When the OpusLaw Team designed Carta AI's architecture, we built it to handle 3,000+ attorneys across 30+ offices from day one. Most AI platforms are built for startups and break under BigLaw pressure."
"Enterprise architecture isn't just about handling load—it's about maintaining security and accuracy at scale."
