Live2D companion runtime
A real Cubism 4 model with physics, idle motion, and cursor tracking — rendered locally, docked into the OS.
Server-side AI execution
Every model call runs through internal API routes. Secrets stay on the server, always.
ElevenLabs voice responses
Optional voice for Koto's replies, proxied server-side and disabled gracefully when unconfigured.
Wallet-based credits
Your address is your account. 20 real tasks a day, tracked per wallet with a visible reset window.
VPS-ready deployment path
The same runtime, architected to install onto Windows, Linux, and macOS machines the moment payment clears.
Private by architecture
The trust boundary is drawn once, at the server. Everything sensitive stays behind it.
Wallet is login
Your Solana address is your identity. No email, no password database, nothing to breach.
API keys remain server-side
Anthropic and ElevenLabs keys never leave the server. The browser only ever talks to internal routes.
Task credits are wallet-based
Usage is metered against your address with a transparent 24-hour reset, visible in the OS at all times.
Explicit payment confirmation
VPS provisioning will only ever run after an explicit, verifiable payment confirmation on-chain.
Rent a machine with Koto OS preinstalled
Four tiers, priced in SOL. Provisioning preview today; instant installs when provider integration is live.
Questions, answered
If something is unclear beyond these, the docs cover the full architecture.
Koto OS is a Live2D AI companion operating system: an agentic desktop layer that runs as a simulated OS in your browser today, and as a preinstalled runtime on rentable VPS machines as provider integration goes live. You connect a Solana wallet, and Koto builds, researches, and summarizes for you inside that environment.
The companion is waiting
