Private Retrieval Learning

Search quality tools usually improve by watching you: clicks become signals, signals become a model, and one day ranking changed and nobody can say why. GNO inverts that. Recording is off until you enable it, only judgments you make explicitly become qrels, exported fixtures contain no source text, and replay compares a candidate against a baseline read-only. It recommends. You promote.

Install GNO Read the docs

Use cases: Reproducing a recurring retrieval miss; Evaluating a ranking or model change on your own corpus; Building private regression fixtures without exporting source text

What it gives you

Local-only trace IDs across query, Capsule, open, cite, and pin outcomes
Explicit relevant, irrelevant, and missing-expected judgments
Bounded inspection, retention, deletion, and physical purge
Deterministic content-free qrels export
Read-only baseline-versus-candidate replay
Stale and missing source disclosure
No upload, hidden click inference, or automatic ranking mutation
