Mary Technology announced on Oct 21, 2026 that its factual‑investigation AI, Mary, now connects to Harvey’s legal‑AI platform. The connector pulls the documents Mary has read and the team’s findings into Harvey, so lawyers can test allegations, compare witness statements to records, and see why certain files were used. When new documents arrive, Mary suggests updates and the revised work appears automatically in Harvey. The move aims to keep litigation teams inside a single workflow while preserving a shared factual foundation.

## The facts

- Integration announced on 2026-10-21 ("today announced an integration with Harvey" – Wed Oct 21 2026).
- Mary is used by over 4,000 lawyers in more than 150 firms.

## Why it matters

Law firms can now maintain and reuse their evidence analyses without switching tools, saving time on document review.
