Midpage is a legal research platform and data provider for litigators and legal technology teams working with US primary law. It searches case law, statutes, regulations, and agency guidance through manual tools or an AI research agent. Users can draft briefs and memos from research and uploaded documents, check citations, and use an AI citator to see how later courts treated an opinion. Midpage states its collection includes 16M+ published and unpublished opinions with metadata, alongside statutes and regulations from all 50 states. It integrates with Claude, ChatGPT, and Perplexity for source-grounded research and drafting; legal data and retrieval tools are available through APIs, MCP, or a database connection. Midpage says safeguards are independently validated through annual SOC 2 Type II and HIPAA audits. Customer data is encrypted at rest and in transit and is not used to train or fine-tune AI models. A 14-day trial is listed; the paid Law Student plan costs $25 a month for one seat before tax and requires proof of US law-school enrollment or employment.
