Show HN: Vilvona AI – Self-Hosted AI Assistant with Tamil and Hindi UI

Vigneshwaran S. released Vilvona AI, a self-hosted AI assistant that connects to messaging and productivity apps including WhatsApp, Telegram, Gmail, and Slack while keeping all data local. The tool features a Tamil and Hindi user interface and runs on personal machines using Anthropic's Claude Fable 5 model, with users paying Anthropic directly per token.

Self-hosted AI assistant that connects all your apps. Powered by Claude Fable 5. Tamil & Hindi UI. Works on mobile. Run anywhere. Get Vilvona Pro https://vignesh2027.mojo.page/vilvona-ai-pro · Docs https://vignesh2027.github.io/Vilvona-AI · npm https://npmjs.com/package/vilvona 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. export ANTHROPIC API KEY=sk-ant-... npx vilvona Open http://localhost:4000 . Done.
