Mary Technology integrates with Harvey to share legal case facts

The system works by mapping uploaded matter documents before questions are asked, organizing people, dates, events, and evidence. It tracks contradictions, gaps, and corroborating material, keeping them visible alongside the work product. Lawyers can use this to assess evidence for allegations, compare witness accounts with documents, and examine financial records. The integration ensures that the team's existing investigation, including qualifications and unresolved questions, carries forward into new AI-assisted tasks.

The workflow includes a review process where lawyers confirm facts and inspect audit history. When new documents affect existing work, Mary suggests updates that users must accept before processing. Mary states that firms retain access control and that customer content is not used to train AI models. The partnership aims to make the quality and continuity of the factual record central to the AI workflow, though no independent benchmarks for error reduction were provided.
