# Bio Manager

Stores and retrieves **per-user biographical notes** — what Synth knows about
the people she talks to (and about herself). A short bio of the current
participants is injected into the prompt so Synth remembers who she is speaking
with. The full detail can be requested on demand.

Backed by the `bio` table.
