Add an AI Avatar to Your Twitch Stream in 3 Steps

Nicolas Jellab Nov 25, 2025

Ever dreamed of having an AI avatar on your stream that not only looks amazing but also interacts with your chat? Imagine combining smooth AI text-to-speech (TTS) with ready-to-use VTubing models, or even your own custom model, to create a fully interactive streaming experience.

With ai_licia, that dream is now a reality. Whether you’re a seasoned Vtuber streamer or just starting out, ai_licia makes it simple to create a personalized AI avatar that brings your stream to life. In this guide, we’ll show you how to get your AI avatar up and running in just three easy steps.

Step 1: Create Your ai_licia Character

The first step is all about personality. Your AI avatar is only as engaging as the character behind it.

With ai_licia, you can:

  • Choose a voice: Pick a voice that fits your style: friendly, energetic, mysterious, or humorous.

  • Define personality traits: Tailor the way your avatar speaks and responds to chat.

  • Customize interactions: Decide how your AI responds to different prompts or messages in your Twitch chat.

Taking the time to build a character that fits your streaming style is key. The more personality your avatar has, the more viewers will connect with it, and with you.

Step 2: Choose or Upload Your Model

Next, it’s time to give your character a face. ai_licia supports multiple types of VTubing models, making it easy to match your character design with your personal style.

Model Types:

  • VRM Models: 3D avatars compatible with most VTubing apps. Perfect if you want a fully three-dimensional look with depth and movement.

  • Live2D Models: 2D avatars with smooth animations. Ideal for stylized or cute designs, giving you expressive and dynamic movements with minimal setup.

Model Options:

  • Default Models: Ready-to-use avatars that work out of the box.

  • Recommended Models: Browse ai_licia’s curated external library of avatars to find the perfect match.

  • Custom Models: Import your own VRM or Live2D models to make your stream truly unique.

Customize Your Avatar Settings:

Once your model is selected, ai_licia gives you full control over key visual settings:

  • Mouth sensitivity: Make sure your avatar’s lips sync perfectly with TTS.

  • Camera angles: Adjust how your avatar is framed on stream.

  • Lighting levels: Optimize how your avatar looks under different lighting conditions.

This step is all about making your avatar feel alive and professional, giving your viewers a visually captivating experience.

Step 3: Add Your Avatar to Your Stream and Go Live

Now that your character and model are ready, it’s time to bring it to your Twitch stream.

  1. Copy the browser source link of your avatar model.

  2. Add it in OBS or Streamlabs OBS by creating a new browser source. Resize and position it to fit your stream layout.

  3. Go Live: On the Go Live page in ai_licia, enable the TTS and let your avatar join the stream.

When your ai_licia speaks, your avatar's mouth will move in sync with ai_licia’s TTS, making interactions feel natural and immersive. Viewers can chat with your avatar in real time, and your AI co-host will respond, creating a dynamic and entertaining streaming experience.

Tips for Getting the Most Out of Your AI Avatar

  • Experiment with voices: Try different TTS voices to see which resonates best with your audience.

  • Adjust animation settings: Small tweaks to mouth movement and camera angles can make your avatar feel more lifelike.

  • Engage with chat: Encourage viewers to interact with your AI avatar. This boosts engagement and makes your streams more memorable.

  • Combine with overlays: Add alerts, emotes, and other overlays to enhance the immersive experience.

✨ And there you have it! In just three steps, you can transform your Twitch stream with a fully interactive AI avatar. With ai_licia, streaming isn’t just about talking to your audience, it’s about creating a unique, dynamic, and unforgettable experience that viewers will love.

Whether you use a default model or bring in a custom creation, your AI avatar is ready to join your stream and engage with your chat, bringing a whole new level of fun and interactivity to your Twitch channel.
