The Cartesia Ecosystem

The operating system for empathetic machines.

Fluidity is the Foundation

Empathy breaks down when there is lag. A pause of even 500ms can turn a conversation into a transaction.

We engineered our entire stack for speed. From our Rust-based TTS engine to our low-latency streaming layer, every component is designed to close the gap between perception and expression. The result is an agent that doesn't just wait its turn—it listens, interrupts, and responds in the blink of an eye.

  • Ultra-low latency streaming architecture.
  • Instantaneous interruption and turn-taking.
  • Seamless, human-like pacing.

Transparent Thought, No Black Boxes

You cannot trust what you cannot see. Most AI platforms are black boxes of probabilistic confusion.

We believe in explicit, designable behavior. Our node-based visual editor allows you to map out your agent's reasoning, combining the flexibility of LLMs with the reliability of deterministic logic. You see exactly why an agent made a decision, and you have the power to change it.

  • Visual, node-based logic design.
  • Determinism where you need it, creativity where you want it.
  • Full state transparency and debugging.

Symphony of Behavior

Humans don't just output text. We gesture, we gaze, we pause, we smile. Text-only AI is missing half the conversation.

Our sequencer allows you to orchestrate the entire performance of an agent. You can sync a subtle nod with a specific word, trigger a smile before a sentence finishes, or manage gaze to show attention. We provide the tools to build a presence, not just a chatbot.

  • Multi-modal sequencing (audio, face, gesture).
  • Rich, non-verbal behavioral cues.
  • Powers physical robots and digital avatars alike.
