Research with a local index
Research is where most writing software stops and AGIT keeps going. Every project can carry its own library: documents and scans imported, indexed on your own machine, searchable in a heartbeat, computable in Python, chartable, and — when you want it — connected to external tools through open protocols.
Novelists use it for the lore archive. Essayists use it for sources. Worldbuilders use it for the invented history of a country that does not exist. The pattern is the same: your material, indexed locally, working for the draft.
