Anthropic expands legal AI tools for law firms
Anthropic is launching new chatbot features for law firms, intensifying competition in a legal AI market recently bolstered by massive funding rounds for startups like Harvey and Legora.
On Tuesday, Anthropic announced the launch of new chatbot features and connectors designed to provide automated assistance to law firms, expanding the capabilities of its Claude model. The release builds upon “Claude for Legal,” a law-focused plug-in that the company launched in February. The new tools are designed to help law firms automate specific clerical functions, including document search and review, case law resources, deposition preparation, and document drafting. According to Anthropic, these plug-ins represent a bundle of automated functions designed to work across legal fields such as commercial, privacy, corporate, employment, product, and AI governance.
The launch arrives as the legal AI sector sees significant capital inflows. In March, the AI law startup Harvey, which uses agentic AI—defined as AI systems capable of performing tasks autonomously—raised $200 million at an $11 billion valuation. Last month, a rival startup, Legora, raised a $600 million Series D and launched an ad campaign featuring actor Jude Law. Legora offers automated solutions built to simplify complex legal processes. According to a spokesperson for Anthropic, “Claude is making a deeper push into knowledge work, with the legal sector emerging as one of its most significant and fastest-growing industries.”
To embed its model into existing legal workflows, Anthropic is deploying Model Context Protocol (MCP) connectors—tools that link AI models to external data sources. These connectors integrate Claude directly into software applications already routinely used by law firms. This includes document management platforms like Docusign, file search platforms like Box, and legal research platforms operated by Thomson Reuters. The new connectors and plug-ins are being made available to all paying Claude customers.
As adoption grows, the legal industry faces scrutiny over AI-generated errors. At least one major law firm has been caught using AI to generate “error-ridden legal documents.” Last year, California issued a fine against an attorney who used AI to draft an appeal riddled with “fake quotes.” Federal judges have also been caught using AI to draft rulings, a trend that drew congressional scrutiny last year. Meanwhile, AI-generated lawsuits are said to be clogging the arteries of justice, overwhelming courts with stacks of “bizarrely argued legal “slop.””
