For Wikipedia and other curated corpora, document retrieval is cryptographic — the server can't see which one you fetched. How it works →
In feudal Japan, Chunin (中忍, "middle ninja") were the elite operatives of the shinobi world — more than raw recruits, yet freer than their commanding Jonin superiors. They were the invisible hand behind intelligence gathering: move without being seen, learn without leaving a trace.
A Chunin's greatest weapon was not a blade — it was information superiority with a lighter footprint. They could gather intelligence while revealing as little as possible to the people and systems watching the route.
Chuninja carries this spirit into the digital age. Private Web search shields your upstream footprint, and PIR Vault adds cryptographic document retrieval for curated indexes. You choose the privacy model that fits the search.
Chuninja is powered by Private Information Retrieval (PIR) — a cryptographic protocol that lets you fetch documents from a server without the server learning which document was fetched. Chuninja pairs useful live search with private reading for the open web, plus PIR retrieval for curated indexes.
