A self that never stops becoming.

The stack.

Applied

  • RPA

    Automated ops across Xiaohongshu, WeChat, Reddit, YouTube.

    Accounts, replies, posting, and the ops a team already runs — Xiaohongshu, WeChat, Reddit, YouTube — without a person on every tab.

    Applied work. Not a product you open. The automation sits behind the work.

  • AEO

    Public acquisition — so models recommend the brand.

    Acquisition used to mean ranking in search. Now it also means being the name a model gives when someone asks.

    We write and place the public record so the brand is what gets recommended. Not ads. Presence.

Media

  • ASR

    Speech to text.

    Speech in. Text out. Lectures, calls, source that starts as voice.

    Infrastructure for everything that has to be read before it can be used.

  • TTS

    Text to speech.

    Text in. Speech out. For presenters, prep, and anything that has to be heard.

    Paired with clone and video. Not a standalone voice app.

  • Voice Clone

    A voice that can be reused.

    A voice captured once, then reused — so the same speaker can appear in new cuts without a new session.

    Used with TTS. The voice is the asset. The clone is the reuse.

Foundation

  • Ontology

    The model underneath.

    The model underneath the stack. What the work is made of, and how the pieces relate.

    Foundation, not a name on the nav. Everything above sits on it.
