README.md

@@ -24,6 +24,8 @@ memU is a memory framework built for **24/7 proactive agents**.
 It is designed for long-running use and greatly **reduces the LLM token cost** of keeping agents always online, making always-on, evolving agents practical in production systems.
 memU **continuously captures and understands user intent**. Even without a command, the agent can tell what you are about to do and act on it by itself.
