# gnosphere.ai > A gn is a knowledge object: a structured, addressed, AI-readable unit of knowing that any AI assistant can retrieve by URI — no scraping, no login required. 'gn' is not an acronym; it is the consonant kernel of the Proto-Indo-European root for 'to know', the same root behind gnosis, cognition, and the silent-k in 'know'.
