This guide walks you through creating a 3D AI agent in the browser — no code, no 3D software, no crypto wallet required.
Time: about 5 minutes
What you'll have at the end: a live 3D AI character you can share or embed on any website
Go to three.ws/start. This is the new-agent wizard.
You'll be asked to sign in if you haven't already. See Do I need crypto? if you're not sure which sign-in option to choose.
The first step of the wizard asks you to choose a body for your agent.
Your options:
- Browse the gallery — hundreds of ready-made 3D characters, from realistic to stylized
- Take a selfie — upload a photo and get a 3D version of yourself in about a minute at /create/selfie
- Upload a GLB — any rigged glTF/GLB file works. Drag it into the editor at /app or import from a URL
Not sure what an avatar is vs. what an agent is? Read Agents vs. Avatars.
Give your agent a name and a short description of who it is. For example:
"You are Aria, a helpful product guide for Acme Corp. You speak in a friendly, concise tone. You know everything about our products and can answer questions about pricing, features, and how to get started."
This description is your agent's system prompt — the instructions it follows. You can always edit it later.
Skills are extra capabilities you can give your agent. Common ones:
| Skill | What it does |
|---|---|
| Voice | Lets users talk to the agent by microphone; the agent responds out loud |
| Memory | The agent remembers past conversations across sessions |
| Web search | The agent can look things up in real time |
You can add or remove skills at any time from the agent's edit page.
Once you hit Publish, your agent gets a live URL — something like three.ws/agent/abc123.
The wizard also gives you an embed snippet: a few lines of HTML you can paste into any webpage to make the agent appear there. You don't need to know HTML to do this — just copy and paste.

Everything is editable after publishing. Go to your agent's page and click Edit. You can change:
- The avatar (swap the body without losing the personality)
- The system prompt / personality
- Which skills are active
- The agent's name, description, and thumbnail
Changes take effect immediately — no republishing needed for most settings.
- Put it on your website → Share & embed
- Understand how it all works → How it works
- Give the agent a custom skill → Create a custom skill
- Make it yours permanently (on-chain) → Register on-chain
