What Long-Term Memory does

The Long-Term Memory (LTM-2.7) Engine captures workflow context on your device so Pieces can surface relevant summaries, timeline activity, and answers in Conversational Search. For a conceptual overview, see Fundamentals.

Turn on Long-Term Memory

  1. Open the Pieces Desktop App.
  2. Click your User Profile (top left), hover Settings, then choose Long-Term Memory.
  3. In the Memory Formation section, ensure the Long-Term Memory Engine is On.

You can also use the PiecesOS Quick Menu in your system tray or menu bar—see PiecesOS Quick Menu for access and shortcuts.

LTM runs **on-device** for privacy. Grant any prompts for **screen**, **accessibility**, or **microphone** (for LTM Audio) when asked—details are in the full settings guide below.
