Technology
Built on real statutes and caselaw — 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 using field specifications extracted from thousands of official court form PDFs, mapped across more than 100,000 form fields.
