AI browser agents have no persistent local memory across sessions

Browser AI agents (BrowserBee, Hacker-Valley Interceptor, ArcRift) can run tasks in the browser but reset state on every session. Users want a local memory layer that persists what the AI learned about their workflows, credentials context, and page patterns across sessions without sending data to cloud. The pain compounds for privacy-conscious users who also need PII filtering before text hits an LLM.
