Question: "Why Repliworld?"

Because presence is fleeting, and memory fades — yet our actions, words, and ideas deserve to last.
Repliworld preserves your presence digitally, so you can be everywhere, anytime.

  • Live AI twins that speak and act like you in real time.
  • Extend your presence across meetings and conversations without being there.
  • Capture your voice, expressions, and style—forever.
  • Turn your ideas into an interactive digital legacy.

Repliworld exists so that you don’t have to choose between being everywhere and being yourself.
Presence, preserved. Life, amplified.

Our mission: to extend your presence infinitely.

# pseudo
              render = NeRF(video)
              voice = TTS(text, speaker=you)
              avatar = sync(render, voice)

Equations: NeRF → f_θ(x,d) and Transformer: y = Softmax(QK^T / √d) V
