KYDONIA

Paste a URL. Index it. Query it.

Mars-class text retrieval

Every page you paste,
queryable in seconds.

KYDONIA fetches a page once, folds it into an inverted index on your device, and ranks every answer with BM25 — deterministic, offline, with the source of each hit attached.

Fetched once, indexed on your device, never shared.
