PHILOSOPHY
your saved knowledge should not disappear into bookmarks, folders, and forgotten notes.
cortex keeps the archive calm: ingest asynchronously, retrieve with hybrid search, compress context with REFRAG, answer with citations.
the point is not more storage. the point is memory you can trust.
