- The page says memories are saved by choice, not automatically captured from everything that scrolls through a chat.
Field notes
The site organizes data as wings (projects), rooms (topics), and drawers (individual memories), stored in a local database. It says memories are saved only when a user or instructed agent chooses them; expected outcomes and actual outcomes remain side by side, and an item too large for a handoff is listed for full retrieval.
