## Summary

Mary Technology has announced a partnership with Harvey to integrate its litigation fact-finding tools into the legal AI platform. The connector allows Harvey to access the matter record maintained in Mary, including prior findings, supporting evidence, and team reviews. This addresses a key gap in legal AI: ensuring that generated answers are backed by a verified factual foundation rather than just raw document extraction.

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.

## Key points

- Mary Technology integrates with Harvey to share verified case facts and evidence records.
- The connector organizes people, dates, events, and evidence, tracking contradictions and gaps.
- Lawyers review and confirm facts; Mary states customer content is not used for AI training.

## Why it matters

This integration addresses the reliability gap in legal AI by linking generated answers to a verified, traceable factual record. It helps lawyers ensure that AI outputs are supported by specific documents and account for conflicting evidence, reducing the risk of hallucinations in litigation work.
