Harvey integrates Mary Technology’s litigation tool to streamline legal AI workflows

What the integration does

Mary Technology, based in Sydney, automates the extraction of key details from legal documents, including people, dates, events, evidence, and conflicting accounts. Its tool organizes this information into a structured record, flagging gaps or inconsistencies in evidence.

Harvey’s integration allows its users to draw on Mary’s checked records while drafting legal documents or conducting research. When new documents alter the case’s facts, Mary suggests updates, which lawyers must approve before they are incorporated.

Mary’s co-founder, Daniel Lord-Doyle, emphasized that law firms retain control over data access and that client files are not used to train AI models.

Funding and expansion

Mary Technology raised $7 million in seed funding earlier in 2026 to expand its operations in the US. The company’s tool is part of a broader push to automate litigation workflows, reducing manual review time for lawyers.

Harvey, which raised $550 million in September 2026 and is valued at $15.6 billion, serves over 3,000 customers. The company released its own legal AI model in August 2026, further expanding its platform’s capabilities.

Broader context: AI in legal tech

The integration follows Harvey’s addition of Autologyx to its Connector Library, which enables further workflow integrations. Competitors like Sweden’s Legora are also developing AI-driven litigation tools, signaling a growing market for automation in legal processes.

For law firms and legal departments, tools like Mary’s reduce the time spent on manual document review, allowing lawyers to focus on higher-value tasks such as strategy and client interactions.
