ExoPriors builds search in pursuit of existential philanthropy.
We put the public internet — forums, papers, books, social archives, prediction markets, government records — behind one queryable surface, and build open instruments for measuring the judgment of AI systems. Crawlers, storage, indexes, the query layer above them: ours end to end.
Scry is operated as a philanthropic service for researchers; every answer keeps its evidence attached. Institutional partnerships: [email protected].

Research
The Judge Coherence Benchmark scores LLM judges against themselves — swap the order, negate the attribute, chain ratios around a cycle — so there is no answer key and nothing to memorize. Public leaderboard across frontier models; every number recomputes from committed per-call records.
A Rust library and CLI for ranking with LLM judges: pairwise ratio judgments fitted into calibrated cardinal scores with uncertainty, active pair selection, budget control, and full cost records. MIT. Pairwise Ratio runs on it.
