Anthropic introduces legal tool for businesses

Anthropic added a legal module to its Claude Cowork tool in February 2026. This module helps businesses review contracts, sort confidentiality agreements, and prepare notes. Anthropic stressed that the tool does not offer legal advice and that its outputs should be reviewed by a lawyer.

Publishing stocks drop after the announcement

Following the release of the new tool, stock prices of major legal publishers fell sharply. RELX, which owns LexisNexis, lost 14 percent in one session, its worst day since 1988. Thomson Reuters and Wolters Kluwer also saw significant declines in their stock prices.

Lefebvre Dalloz resists external collaboration

Julien Tanguy, general director of Lefebvre Dalloz, stated that the company will not share its content with other companies. He emphasized the importance of maintaining control over content and customer relationships. The company has a family shareholdership that supports long-term planning and is focusing on its internal development with the GenIA-L tool.

Legal publishing sector sees consolidation

In one month, LexisNexis acquired Doctrine, and Lextenso joined C.H. Beck, which also acquired Noxtua. Lefebvre Dalloz remains the only independent legal publisher with a French family shareholdership. This positions it as a key player in offering a European legal platform based on local content.

Lefebvre Dalloz continues traditional publishing

Despite a 20 percent decline in paper revenue, Lefebvre Dalloz publishes 300 new titles annually. The company aims to maintain the quality of its content and ensure that its books carry its history and heritage. The accessibility of judicial decisions and AI's ability to summarize them quickly have raised concerns about the value of expert legal information.

Investors take interest in legal AI startups

Morgan Stanley noted the rapid rise of startups providing AI tools to lawyers. Many of these startups use large AI models without relying on traditional legal publishers' databases. Investors are questioning whether legal databases remain valuable if general AI can access legal information directly.

Legal AI startups secure major funding

Startups in the legal AI space are raising large sums. Harvey, an American AI assistant for law firms, raised $550 million in 2025. Legora, a Swedish competitor, achieved over $100 million in recurring revenue quickly. Clio, a Canadian software publisher, acquired the legal database vLex for $1 billion.

Global legal publishers invest in AI technology

Thomson Reuters and Wolters Kluwer are acquiring AI-based legal tools to stay competitive. Thomson Reuters spent $650 million on Casetext in 2023 and plans to invest $11 billion by 2028. Wolters Kluwer paid €425 million for Brightflag, and RELX acquired Doctrine for an estimated €500 million.

French legal publishers adopt different strategies

In France, three major strategies have emerged. LexisNexis has absorbed its main competitor and now holds €200 million in revenue. Lextenso has joined C.H. Beck, which also acquired Noxtua. Lefebvre Dalloz, a French family-owned group, is focusing on its internal development with the GenIA-L tool.

Legal publishers highlight the importance of content quality

All major legal publishers argue that the effectiveness of legal AI depends on the quality of its sources. Guillaume Carrère of LexisNexis, which now owns Doctrine, claims that general AI lacks access to comprehensive legal data compared to their products. Paper revenue is declining, but digital growth is more significant.

Lefebvre Dalloz invests in AI with its own content

Lefebvre Dalloz continues to publish 300 new titles annually, but its paper revenue is down 20 percent. Lextenso, a leading French legal publisher, sees paper as a crucial pillar. Emmanuelle Filiberti of Lextenso notes that while AI is becoming more accessible, the quality of the data sources remains critical.

AI adoption by legal professionals is cautious

At Lefebvre Dalloz, the GenIA-L tool is built solely on the company's content. Julien Tanguy states that two out of three new sales are for their AI solution. A survey by LexisNexis found that 67 percent of legal professionals prioritize the reliability of sources when choosing AI tools, over data confidentiality. However, only 27 percent of those with AI access use it regularly.

General AI models improve but face competition

General AI models like Claude, ChatGPT, and Gemini are becoming more capable of handling legal texts. Publishers like Thomson Reuters use these models while developing their own tools. The gap between general AI and specialized publisher tools is narrowing, but publishers still hold an advantage with their content. The race for dominance in legal AI is just beginning.
