Commentari closes the gap between fast-issued federal rules and stakeholder response. Built by Eric Epstein, former DOJ/ATF senior policy counsel & Ghost Gun Rule author, it offers expert guidance. It summarizes complex rules, identifies APA issues, and helps users draft unique, substantive comments in their own voice. Submissions go directly to Regulations.gov & Congress. Organizations get branded campaigns, rule tracking, and engagement metrics. No templates. Your unique argument, on record.
