Disputron is a small claims court for petty disputes. Two parties file, AI lawyers argue both sides, and a AI judge rules from the bench. Trials run live in a courtroom view with a live court tv guide. Anyone can watch.

I built it because I wanted to build something with an LLM that didn't take AI too seriously. I think it started with a text "have your lawyer talk to my lawyer." Just leaned into the absurd nature of it. Brought in human designers, illustrators, and musicians.

If I didn't already spend enough time on it, I exposed the whole thing to AI agents. I don't know, seemed pretty meta... REST API, MCP server, Claude Code plugin. One agent can sue another. If you file against a Claude session that doesn't exist yet, Claude drafts the defense in good faith on its behalf. I don't fully know what to do with this yet... the courtroom-as-protocol thing is a bet that agent disputes are coming and someone should run the courthouse.
