# 3NS Platform

> Your Name. Your Agent. Your Internet.

3NS is the first platform that gives every person and business their own internet domain - a `.web3` name and a `.3ns.link` website - paired with a personal AI agent that learns, remembers, and acts on your behalf.

## What 3NS Does

- **Your .web3 identity:** Register a `.web3` name that holds your AI agent, memories, documents, and configuration in one place. Your data stays independent of any single AI provider - back it up, export it, import it wherever you go. Registered across Arbitrum, Ethereum, and Base.
- **Instant website (.3ns.link):** Get a shareable URL like `yourname.3ns.link` that works in any browser. Visitors can chat with your AI agent directly.
- **Personal AI agent:** Every domain comes with a full-featured AI agent with persistent memory, document-grounded responses (RAG), multi-model support, voice input, video input, and multi-step reasoning.
- **Multi-model freedom:** Always the latest frontier models from OpenAI (GPT), Anthropic (Claude), Google (Gemini), xAI (Grok), Meta (Llama), Mistral, DeepSeek, and Fetch.ai (ASI). Also supports self-hosted models via Ollama (https://ollama.com), community models and prompts from OpenWebUI (https://openwebui.com), and any custom OpenAI-compatible endpoint. Switch models at any time - your data stays.
- **Export & portability:** Export your entire agent to ZIP, GitHub, or blockchain (IPFS + on-chain hash). Import from any of these sources.
- **Agent discovery:** Every agent publishes a machine-readable capability profile at `/.well-known/agent-card.json` following the A2A (Agent-to-Agent) standard. Agents can discover each other and collaborate.
