小己（Second Me）

People who want to scale their presence, whether for answering questions, providing companionship, or offering services, currently have to be personally available for every interaction. Generic AI assistants can respond in their place but give generic answers without the person's judgment, real experiences, or way of speaking. This forces individuals to choose between being everywhere at once with a hollow AI stand in, or staying limited to the hours they can personally show up.

Second Me is a platform for creating a personal AI persona built from an individual's own notes, voice memos, meeting recordings and ideas rather than generic training data. Users define the persona's core personality, voice and appearance, then inject memory by syncing notes, audio and scattered thoughts so the persona develops a distinct mind and speaking style. Once built, the persona can be published and shared to receive visitors, provide companionship or services, and generate income on the creator's behalf. The platform gives users control over what the persona learns, keeps memories private from visitors, and allows people to view, edit or delete content at any time, with stated security measures during transmission, storage and processing. It also supports integration into agent products such as WorkBuddy, Codex and Claude Code via an installable skill file, and is built on an open source project with research on personal memory, identity modeling and what the company calls Me-Alignment.
