Lighthouse Brings AI-Powered Search to UK and Europe
Lighthouse, a leader in human-centred technology and services for eDiscovery and information governance, has announced the availability of Lighthouse AI Search in the UK and Europe. Law firms and legal and compliance departments in those markets can now leverage the company’s AI-driven indexing, retrieval, and analysis technology.
Already in use by the United States operations of more than 50 multinational and global corporations and law firms, the application enables legal teams to surface critical facts quickly, reveal key topics and people, and identify important evidence across millions of documents, all without requiring users to be experts in prompting. By asking plain-language questions, Lighthouse AI Search dramatically improves users’ ability to uncover strategic insights from data more quickly.
Modern litigation and regulatory investigations in the UK and Europe increasingly involve vast sets of unstructured data. Traditional review methods can be time-consuming, costly, and difficult to scale. Lighthouse AI Search addresses new regulatory and litigation realities by leveraging purpose-built large language models (LLMs) to interpret natural-language queries, analyse enormous document sets, and return sourced answers within minutes.
Lighthouse AI Search is built to support legal workflows common to outside counsel and in-house legal and compliance teams, including early data assessments, incoming production analysis, outbound production quality control, trial and witness research, and internal investigations.
The AI Search backend performs sophisticated prompt engineering on the users’ behalf, often orchestrating multiple queries to assess document pertinence, analyse relevance, and then synthesise a precise answer to the user’s question, grounded solely in their dataset. The result is improved early data assessments, production analysis, outbound production quality, trial and witness research, and internal investigations.
“The legal markets in the UK and across Europe are moving quickly toward practical, defensible adoption of AI,” said Mike Brown, President, EMEA at Lighthouse. “Clients are dealing with more data, tighter timelines, and increased pressure to achieve efficiency without sacrificing quality. Lighthouse AI Search meets that moment by making AI genuinely usable for every legal and compliance professional.”
AI Search is designed to align with UK data protection expectations, including the UK GDPR, helping organisations confidently use advanced AI while maintaining responsible data handling practices. As part of an ongoing commitment to responsible and transparent AI development, Lighthouse is working toward a formal General Purpose AI (GPAI) designation for AI Search under the EU AI Act — an alignment already reflected in the product’s architecture and operational approach — with final designation expected in accordance with the Act’s rolling implementation timelines.
