AI 法務サービス業界が活況、Anthropic も参入へ

Anthropic announced Tuesday that it is launching a host of new chatbot features designed to provide automated assistance to law firms. The new features expand Claude for Legal — the law-focused offering that launched earlier this year — offering users a new set of legal plugins and MCP connectors designed for specific areas of law.

The new tools come amid hot competition in the legal AI space. In March, the AI law startup Harvey, which uses agentic AI to automate legal workflows, raised $200 million at a valuation of $11 billion. Last month, a rival startup, Legora, raised a $600 million series D, and launched a high-profile ad campaign featuring Jude Law. Legora offers similar services to Harvey — automated solutions built to simplify the often byzantine law processes that have traditionally involved entire teams of humans.

Anthropic’s new tools are designed to help law firms automate specific clerical functions — things like document search and review, case law resources, deposition prep, document drafting, and other related areas. The plugins — which represent a bundle of functions and automated tools — are designed to work across legal fields like commercial, privacy, corporate, employment, product, and AI governance, Anthropic says.

Anthropic is also offering a number of model context protocol connectors. MCPs connect specific data sources and third-party systems to AI models, allowing the models to interact with them directly. In this case, the new MCP connectors integrate Claude into a variety of software applications that are already routinely used by law firms — applications for document management like DocuSign and file search platforms like Box. Legal research sites like Thomson Reuters (which operates Westlaw) can also be connected.

The new connectors and plugins are being made available to all paying Claude customers, the company said. The new features also build upon other plugins designed for the legal industry that the company launched in February.

“The legal sector is facing mounting pressure to adopt AI, and the firms and in-house teams that move are pulling ahead fast,” a spokesperson for the company said. “Claude is making a deeper push into knowledge work, with the legal sector emerging as one of its most significant and fastest-growing industries.”

As AI companies have sought to court law firms, AI-related failures have caused real problems in court. Dozens of lawyers have been caught using AI to generate error-ridden legal documents, as has at least one major law firm. Last year, California issued a first-of-its-kind fine against an attorney who had used ChatGPT to draft an appeal riddled with fake quotes. Federal judges have also been caught using it to draft rulings, a trend that drew the scrutiny of Congressional leaders last year. Meanwhile, AI-generated lawsuits are said to be clogging the arteries of justice — overwhelming courts with stacks of bizarrely argued legal “slop.”
