What it is
MemPalace stores your conversation history as verbatim text and retrieves it with semantic search. It does not summarize, extract, or paraphrase. The index is structured — people and projects become *wings*, topics become *rooms*, and original content lives in *drawers* — so searches can be scoped rather than run against a flat corpus.
The retrieval layer is pluggable. The current default is ChromaDB; the interface is defined in [`mempalace/backends/base.py`](mempalace/backends/base.py) and alternative backends can be dropped in without touching the rest of the system.
Nothing leaves your machine unless you opt in.
