AI thatremembers.Answers fromyour data.

We build AI memory, search and document intelligence, and the apps that use them. From an assistant that keeps useful context to a complete product with its own interface and APIs.

Legal research · Web and iPhone

MayaClerk

Web: live
iPhone: built and tested, not yet in the App Store

A legal research service. Hybrid search across case law and the U.S. Code, a research assistant that cites what it read, and a reader for the user's own documents. One backend serves the website and a native iPhone app. Its Dossiers set three research agents on one claim: two opposing counsel and a reporter who reconciles them.
