What is this?

I built Vilvona AI because I wanted a personal AI assistant that could connect to WhatsApp, Telegram, Gmail, Slack, and everything else I use — without sending my data to some cloud service.

It runs entirely on your own machine. You bring your Anthropic API key, and Vilvona handles the rest. Your conversations stay local. You pay Anthropic directly per token — no markup, no middleman.

The two things that make it different from everything else I found:

Tamil and Hindi — I'm from Chennai. I wanted an AI assistant that actually works in Tamil, not just pretends to. Vilvona has a full Tamil and Hindi interface built in.

Claude Fable 5 by default — Anthropic's most capable model, set as the default. 1 million token context. Computer use. The best reasoning available right now.

Start in 30 seconds

export ANTHROPIC_API_KEY=sk-ant-... npx vilvona

Open http://localhost:4000. Done.

Get an API key at console.anthropic.com — it's free to sign up, you only pay for what you use.

Install

npx — no install, always latest

npx vilvona

yarn

yarn dlx vilvona

pnpm

pnpm dlx vilvona

global

npm install -g vilvona

Windows (PowerShell):

$env:ANTHROPIC_API_KEY = "sk-ant-..." npx vilvona

Docker:

docker run -e ANTHROPIC_API_KEY=sk-ant-... -p 4000:4000 ghcr.io/vignesh2027/vilvona-ai

AI Models

export VILVONA_DEFAULT_MODEL=fable # Claude Fable 5 — default, best reasoning export VILVONA_DEFAULT_MODEL=opus # Claude Opus 4.8 — balanced export VILVONA_DEFAULT_MODEL=sonnet # Claude Sonnet 4.6 — fast

Or set it in ~/.openclaw/config.json:

{ "defaults": { "model": "anthropic/claude-fable-5" } }

Mobile

Vilvona works as a mobile app without any app store. On your phone, open http://your-ip:4000 and tap "Add to Home Screen." It installs like a native app on both iOS and Android.

How it works under the hood

npx vilvona └── openclaw.mjs checks Node.js 22+ └── downloads openclaw runtime → ~/.vilvona/runtime/ (first run, ~97MB) └── sets OPENCLAW_DEFAULT_MODEL=anthropic/claude-fable-5 └── starts web UI at localhost:4000

The first run downloads OpenClaw's runtime bundle once. After that, everything starts in under a second from cache.

Releases

Releases are automatic. Pushing a v* tag runs the CI checks and publishes to npm + creates a GitHub release.
