Swarm Studio

Drop in a launch plan, price change or policy draft and ask one question. Claude maps who is involved, casts up to 150 agents and lets them post and argue on a mock microblog and forum. You get a report with charts, the loudest threads and an analyst write-up, then you can interview any agent. Free and open source. It runs as a private artifact on your own Claude plan, with no API key and no server.
