Technology
Built on real statutes and case law, not generic AI
Every declaration Onbello drafts is grounded in state statutes and appellate caselaw. It retrieves citations from an indexed corpus of statutes and case law rather than generating them, then writes in the same voice attorneys use in court.
Court forms are filled from the field specifications in the official court form PDFs, so what prints matches what the clerk expects.
