Anthropic's legal department has built custom AI workflows that go beyond simple document review, according to a new report on how the company's in-house counsel uses its own technology.
The AI company, which filed confidentially for an initial public offering this summer, has integrated its Claude assistant into daily legal operations. The legal team uses the tools for contract analysis, regulatory research, and drafting support, with attorneys reviewing AI output before it reaches external parties.
The approach reflects a broader shift in how legal departments deploy generative AI. Rather than treating AI as a replacement for lawyers, Anthropic's team uses it to handle preliminary work so attorneys can focus on judgment calls and strategy.
Building custom workflows
Anthropic's legal team didn't adopt off-the-shelf AI tools wholesale. Instead, they built custom workflows tailored to their specific practice areas, the report said. That includes using Claude to summarize lengthy documents and identify potential issues before a lawyer reviews the material.
The team also uses AI for consistency checks across contracts and other legal documents, helping ensure language aligns with company standards. The workflows are designed to keep humans in the loop, with attorneys making final decisions on anything that carries legal weight.
For legal professionals exploring similar approaches, AI for Legal training can help identify where these tools fit into existing workflows without disrupting established processes.
Scaling the legal function
As Anthropic prepares for its public offering, the legal department faces increasing demands. AI tools help the team manage larger volumes of work without proportional headcount growth, the report indicated.
The company has also hired a lead for its legal AI tools, signaling that this is a permanent part of the operation rather than an experiment. That role focuses on improving how the legal team interacts with Claude and other AI systems.
One key detail from the report: the AI outputs are treated as starting points, not final answers. Attorneys verify citations, check reasoning, and apply their own judgment before relying on anything the AI produces.
Why this matters for legal professionals
The takeaway for in-house counsel isn't that AI will replace legal work. It's that AI can absorb the repetitive, high-volume tasks that consume attorney time, freeing lawyers to focus on analysis and advice.
Anthropic's model - custom workflows, human review, and a dedicated lead for AI tools - offers a template for legal departments at any size. The companies that benefit most will be those that define clear boundaries for AI use and build review processes that keep lawyers accountable for final output.
