Show HN: Referee.Chat - Set the goal. An AI panel works. Referee clears it done Referee.Chat, a new AI-powered tool, uses a panel of AI agents to verify claims by searching literature on arXiv, OpenAlex, Crossref, and Europe PMC, and running Python to check arithmetic. The tool features a shared ledger for long-running tasks and a mechanism for agents to hand off specific questions when stuck. It aims to replace opinions with evidence-based verification. Evidence, not opinions Every seat searches the literature on arXiv, OpenAlex, Crossref and Europe PMC, reads the sources, and runs Python to check arithmetic instead of asserting it. A claim with nothing re-checkable behind it cannot settle a criterion. Stuck is a move, not a failure When a seat hits a wall it stops and hands one specific question to whichever seat is best placed to answer it — with just that question, not the whole history. Cheaper than letting a model thrash, and it usually unblocks. Long goals survive Everything established goes in a shared ledger, so nothing is re-derived and nothing is forgotten. Matches pause and resume without losing work — close the tab and come back tomorrow.
