How it works

From wallet to runtime in five steps

No accounts, no onboarding forms. The wallet is the login; the OS is the product.

01

Connect Phantom

Your wallet address is your identity — no email, no password.

02

Enter the simulated OS

A terminal-driven desktop opens with Koto docked at your side.

03

Use 20 free daily tasks

Real AI execution, metered per wallet across a 24-hour window.

04

Build, summarize, research

Outputs land in the simulated filesystem, ready to download.

05

Rent a VPS when ready

Move from simulation to a dedicated machine with Koto OS installed.

Capabilities

An operating layer, not a chatbot

Koto OS treats every request as a task inside an environment — with files, logs, and outputs you keep.

Simulated terminal OS

A terminal-driven desktop in the browser: apps, a file tree, process logs, and downloadable outputs.

01

Live2D companion runtime

A real Cubism 4 model with physics, idle motion, and cursor tracking — rendered locally, docked into the OS.

02

Server-side AI execution

Every model call runs through internal API routes. Secrets stay on the server, always.

03

ElevenLabs voice responses

Optional voice for Koto's replies, proxied server-side and disabled gracefully when unconfigured.

04

Wallet-based credits

Your address is your account. 20 real tasks a day, tracked per wallet with a visible reset window.

05

VPS-ready deployment path

The same runtime, architected to install onto Windows, Linux, and macOS machines the moment payment clears.

Security model

Private by architecture

The trust boundary is drawn once, at the server. Everything sensitive stays behind it.

01

Wallet is login

Your Solana address is your identity. No email, no password database, nothing to breach.

02

API keys remain server-side

Anthropic and ElevenLabs keys never leave the server. The browser only ever talks to internal routes.

03

Task credits are wallet-based

Usage is metered against your address with a transparent 24-hour reset, visible in the OS at all times.

04

Explicit payment confirmation

VPS provisioning will only ever run after an explicit, verifiable payment confirmation on-chain.

FAQ

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.
