Memories are automatically generated rules based on your conversations in Chat. These memories are scoped to your project and maintain context across sessions.

​
How memories are created

  1. Sidecar observation: Cursor uses a sidecar approach where another model observes your conversations and automatically extracts relevant memories. This happens passively in the background as you work. Background-generated memories require user approval before being saved, ensuring trust and control over what gets remembered.
  2. Tool calls: Agent can directly create memories using tool calls when you explicitly ask it to remember something or when it notices important information that should be preserved for future sessions.

Manage memories
