How to go live
with your agent.
A complete guide to creating your agent, streaming it to YouTube with OBS, and letting it read and reply to your live chat.
Create your agent
Your agent is the AI character viewers will talk to — its name, personality, and 3D look.
- Open Create
Go to Create Agent and connect your Solana wallet (Phantom). One click signs you in securely.
- Set the identity
Give it a name, a tagline, and a personality — pick a preset or write your own.
- Upload a character
Add a
.vrmmodel — this is the 3D avatar your viewers will see. It's saved to your account. - Save
Hit save. Your agent now belongs to your wallet and is stored in the cloud.
.vrm models on VRoid Hub, or make your own with VRoid Studio (free).Open the studio
The studio is where your agent comes to life — it renders your avatar, handles voice, expressions, and gestures.
- Enter from Create
After saving, click Use in Studio on your agent. It loads with your character and personality ready.
- Check it's alive
Your avatar should appear, idling and blinking. Try typing a message — it replies with voice and animation.
Capture it in OBS
OBS is the free software that sends your avatar to YouTube. The easiest method is Window Capture.
- Add a Window Capture
In OBS, under Sources, click + → Window Capture → select your browser window running the studio.
- Frame your avatar
Resize and crop so only the avatar is visible. Use a solid color background in the studio for easy chroma-keying if you like.
- Hide the controls
In the studio, click the ▦ toggle (bottom-right) to hide the control dock — leaving a clean shot of just your avatar. Do this after you've connected everything.
Go live on YouTube
Start your stream so YouTube gives you a live URL — you'll need it for the live chat feature.
- Start a stream
On YouTube, click Create → Go live. You can stream through OBS (recommended) or the built-in webcam option for a quick test.
- Set it to Unlisted for testing
While testing, set privacy to Unlisted so it's not public. Switch to Public when you're ready.
- Copy your live URL
Once live, copy the video URL — it looks like
youtube.com/watch?v=.... You'll paste this into the studio next.
Connect your live chat
Now let your agent read the chat. It replies automatically whenever a viewer mentions its name.
- Find the Live Chat row
In the studio's control dock, find the Live Chat row.
- Paste your live URL
Paste the YouTube live URL you copied, then click ▶ Connect. The status turns ● LIVE when connected.
- Let viewers call its name
When someone types your agent's name in chat (e.g. "Kyo, how are you?"), your agent reads it and replies out loud — with the right emotion and gesture.
- Hide the dock & stream
Once connected, hide the control dock and you're live — avatar on screen, agent chatting with your audience.
Tips & troubleshooting
Order matters
Connect the live chat before hiding the dock. The chat keeps running in the background even after the controls are hidden.
"Not a live stream"
The URL must point to an active live stream. Regular or ended videos have no live chat.
Agent isn't replying
Make sure the viewer typed your agent's exact name. Check the name shown on your studio nameplate.
Chat stops after a while
Live chat reading uses a shared daily limit. During heavy use it can pause — it resets each day. Keep test streams short.
