Legal AI Moves From Isolated Pilots to Firm-Wide Deployments
Legal AI is shifting from isolated pilot projects to enterprise-wide, strategic deployments in law firms.
Why it matters: Firms are reporting concrete gains, such as attorneys saving up to 20% of their weekly work time and revenue increases. As AI becomes deeply embedded in legal operations, firms must proactively address new risks and manage organizational change to maximize its value.
- Generative AI use among legal professionals surged to 69% in 2026, from 31% in 2025.
- Law firms grew legal tech investment by nearly 11% in 2025 as AI adoption advanced.
- 62% of lawyers say AI tools save them 6%–20% of working hours weekly, with 52% seeing similar revenue lifts.
- Pinsent Masons' partnership with Legora highlights a shift to long-term AI integration.
The legal sector is rapidly evolving, with use of generative AI among legal professionals more than doubling in just one year. According to survey data, 69% now use these tools, compared to 31% in 2025.
- Direct efficiency gains are evident: 62% of lawyers save 6%–20% of work hours weekly using AI, while 52% report comparable revenue improvements.
- Investment is following results—law firms increased tech spending by nearly 11% in 2025 to accelerate AI adoption according to LawNext.
This shift reflects a move beyond experimentation. For example, Pinsent Masons has advanced from a pilot to a global strategic partnership with tech provider Legora, embedding AI throughout core legal operations.
Widespread adoption also now extends to in-house teams: 87% of general counsel report using generative AI, nearly twice the percentage from the prior year.
Leaders in the field say the next phase involves AI systems that not only generate text but also coordinate multiple steps or agents—a workflow approach. Sean Fitzpatrick, LexisNexis CEO, predicts these will become “embedded in the core operating model” of top law firms. Bethany P. Withers, a partner at Goodwin, adds, “AI is no longer experimental for the legal profession.”
Stanford Law professor David Engstrom envisions future lawyers as "symphony conductors," bringing together AI outputs and legal expertise to solve complex problems.
The main challenge ahead: integrating AI at scale while developing governance, training, and risk management to support responsible, firm-wide use. For busy legal leaders, the cost of inaction grows as competitors build on these advances.
By the numbers:
- 69% — Legal professionals using generative AI in 2026 (up from 31% in 2025)
- 62% — Lawyers saving 6%-20% of hours weekly with AI tools
- 11% — Rise in firm tech investment in 2025 attributed to AI adoption
Yes, but: The pace and scale of adoption may outstrip some firms' capacity to address related risks, such as data privacy and uneven skillsets.
What's next: Expect further clarification on ethical and regulatory guidance around large-scale legal AI deployment in the coming year.
