Why it matters

Harvey has launched a connector that brings Midpage's U.S. legal research library into Harvey Assistant. Users can run Midpage searches from inside drafting threads and receive cited sources in the final output. The library covers case law, statutes, regulations, and agency materials. Access requires both a Harvey account and a Midpage subscription, so only firms using both products can use it. Announced workflows include research memos, briefs and motions, citation review, and statutory and regulatory questions. The connector also lets Harvey's assistant check whether cited authorities exist and support the propositions they are cited for. Midpage, founded in 2022 and headquartered in New York, built its case law database in-house rather than licensing it from providers such as Fastcase. Its CEO, Otto Zastrow, said the connector keeps research and drafting in one place.

The announcement does not disclose pricing or how the connector is priced beyond the requirement for a Midpage subscription. Midpage's user count is also inconsistent across its materials: it reports 300+ law firms using Midpage or its integrations, while its own materials cite 200+ firms. In early 2025, Zastrow said Midpage had full coverage of U.S. case law, including all federal appellate and trial cases and state appellate cases. It does not cover state trial court cases, which attorneys practicing in state trial courts should account for. Harvey's existing legal research relationship with LexisNexis is limited in scope.

The launch reflects a broader push by legal AI vendors to supply verified primary law inside drafting tools instead of separate research products. Rival Legora has expanded its own research offering, including through its acquisition of Wexler. For firms already on Harvey, the practical question is whether Midpage's coverage gaps matter for their practice areas and whether they want to add a second subscription. Firms weighing Midpage against incumbents should test its state trial court gap against their own matters before committing.
