AI-native Memory 2.0: Second Me

Human interaction with the external world fundamentally involves the exchange
of personal memory, whether with other individuals, websites, applications, or,
in the future, AI agents. A significant portion of this interaction is
redundant, requiring users to repeatedly provide the same information across
different contexts. Existing solutions, such as browser-stored credentials,
autofill mechanisms, and unified authentication systems, have aimed to mitigate
this redundancy by serving as intermediaries that store and retrieve commonly
used user data. The advent of large language models (LLMs) presents an
opportunity to redefine memory management through an AI-native paradigm: SECOND
ME. SECOND ME acts as an intelligent, persistent memory offload system that
retains, organizes, and dynamically utilizes user-specific knowledge. By
serving as an intermediary in user interactions, it can autonomously generate
context-aware responses, prefill required information, and facilitate seamless
communication with external systems, significantly reducing cognitive load and
interaction friction. Unlike traditional memory storage solutions, SECOND ME
extends beyond static data retention by leveraging LLM-based memory
parameterization. This enables structured organization, contextual reasoning,
and adaptive knowledge retrieval, facilitating a more systematic and
intelligent approach to memory management. As AI-driven personal agents like
SECOND ME become increasingly integrated into digital ecosystems, SECOND ME
further represents a critical step toward augmenting human-world interaction
with persistent, contextually aware, and self-optimizing memory systems. We
have open-sourced the fully localizable deployment system at GitHub:
