Artificial intelligence (AI)

Discover new opportunities for value creation.

AI has the potential to transform almost every aspect of our lives, offering unprecedented opportunities for innovation and efficiency. Despite the challenges of safely deploying Artificial Intelligence and core features of GenerativeAI into business models, the potential rewards are significant. Strategic legal guidance is essential for businesses to confidently navigate the AI landscape, ensuring seamless adoption of these technologies and compliance with emerging regulations.

We specialise in providing AI legal advice to the world’s leading organisations, helping them to unlock new pathways for growth and innovation. Our expertise covers the full spectrum of AI integration - from transactional risk assessments, navigating data privacy and IP concerns, to adhering to the EU AI Act.

Our firsthand experience in transforming our own operations by adopting AI and developing solutions like Percy, our bespoke AI tool, grants us unique insights of the technology’s capabilities and risks. This experience enables us to empower and guide in-house legal and compliance teams to fully leverage the potential of this transformative technology.

Percy has been named the winner in the innovation in AI category at the FT Innovative Lawyers Awards 2025, a prestigious award highlighting the success of the development and widespread adoption of Percy across the firm. Discover more about FT AI innovation award.

Expert legal support on all aspects of AI

We provide comprehensive advice on artificial intelligence law, regulation and policy, having developed a market-leading international practice over the past seven years that is grounded in deep industry expertise.

Our Simmons AI Group, made up of around 130 lawyers, data scientists and AI engineers, advises clients across practice areas and jurisdictions on the risks and opportunities associated with the technology.​​

We apply advanced data science, artificial intelligence and other cutting-edge technologies to make our legal advice more efficient, accessible and effective for clients.

The vast portfolio of services we offer is reflected in our AI Toolkit - a free online resource designed to assist your teams in understanding and implementing regulatory compliance. The toolkit also helps build a robust governance framework to address the challenges of AI, including compliance with the EU AI Act - an important regulation that impacts any organisation using or dealing with AI.

Empowering in-house legal teams to accelerate AI adoption

We have also put our AI expertise into action through our AI Readiness services. By combining insights from our global Generative AI division, the legal and regulatory expertise of our AI Group, and the innovation-driven capabilities of our Wavelength team, we equip in-house teams with the tools and knowledge they need to adopt AI successfully.

We start with market intelligence - keeping you up to date on the latest AI tools, trends and developments in legal and compliance. Our team provides detailed insights into key AI tools and their use cases, helping you identify opportunities to create value and gain a competitive advantage.

Next, we help you build a clear path for AI implementation. From creating AI strategies to developing roadmaps, delivery plans and pilots, we make sure your team is ready for a seamless transition. We also guide you in curating data for generative AI models and integrating them into your operations.

Finally, we support your team in adopting AI tools. From prompt engineering and creating a prompt library to exploring and developing custom AI tools using your own models, we equip you with the skills you need to manage and advance the technology independently.

Transforming our own operations through AI

Our expertise isn’t just theoretical; it’s based on experiences of integrating AI throughout our own operations - from legal processes to customer insights and digital marketing.

This includes the development of our bespoke AI tool, Percy, named after one of the founding twins of the firm. Powered by OpenAI's GPT4o, Percy has been significantly customised with unique, in-house-developed enhancements to elevate its functionality, making it fit for a top international law firm. Percy is exclusively available within our internal environment, offering added safety and security. It empowers our team to generate comprehensive responses, summarise texts, and draft documents more efficiently. Percy helps free up valuable time for more complex tasks, adding value to the work we do for our clients.

Market-leading, award-winning AI legal services

Simmons’ partners have co-authored several key AI law textbooks, including Artificial Intelligence Law and Regulation, Artificial Intelligence in Finance, and the latest edition of The Law of Artificial Intelligence.

As thought leaders, we regularly speak at prestigious events like the United Nations and the CogX AI conference. Our Global AI Lead, Minesh Tanna, is a recognised figure in the legal AI community, serving as Chair of both the Society for Computers and Law (SCL) AI Group and the City of London Law Society (CLLS) AI Committee.

And through our AI View newsletter, we share insights and provide regular updates on key legislative, regulatory and policy developments, keeping our clients ahead of the curve.

Our expertise in AI has earned us industry-wide recognition. We’re proud to be listed as a top 50 most innovative firm by the Financial Times and named Tier 1 in the Legal 500 UK’s inaugural AI rankings for 2025.

Our groundbreaking work on the world’s first AI Explainability Statement, which received input from a regulator, earned praise at both the Legal Innovation Awards 2022 and the Financial Times Innovative Lawyers Awards Europe 2022.

But it’s Percy, our bespoke AI tool, that has truly set us apart as a legal technology leader. We were honoured at the FT Innovative Lawyers Awards for its development, and Drew Winlaw, Global Large Language Model Lead, was shortlisted as Intrapreneur of the Year for his work on the tool.
