Midpage is a Brooklyn-based legal research startup channeling the spirit of Casetext, aiming to make AI a trustworthy partner for legal research and drafting by grounding it in real, comprehensive primary law. A persistent problem with general-purpose AI in legal work is hallucinated or fabricated citations; Midpage addresses this by giving its AI direct access to a complete corpus of US case law, statutes, and regulations across federal and state courts, complete with a citator to check whether authorities are still good law.
The platform supports the full research-to-draft workflow. Litigators can research case law, draft briefs, check citations, and retrieve dockets, with the AI surfacing relevant authorities and propositions grounded in actual opinions. Midpage achieved what it describes as full coverage of US opinions and laws, a meaningful milestone given that comprehensiveness is essential for trustworthy legal research, and it launched a novel proposition search feature that lets users find cases supporting a specific legal proposition.
Midpage raised a $4 million seed round in mid-2025, building on $2.2 million raised in 2024, for total seed funding of about $6.2 million. Investors across its rounds include LEA Partners and other venture backers, and the company has positioned itself as an accessible, AI-native alternative to legacy research platforms. A distinctive strategy is its availability not only as a standalone product but also as integrations with Claude, ChatGPT, and Perplexity, meeting lawyers inside the AI tools they already use.
Midpage competes in the legal research market long dominated by incumbents like Westlaw and LexisNexis, as well as newer AI entrants. Its differentiation lies in full case-law coverage, a citator for reliability, proposition search, and an integration-first distribution model. By focusing on grounding AI in authoritative primary law, Midpage targets the core trust problem that has limited AI adoption in litigation research and drafting.
