Frequently asked questions
What is an AI avatar?
An AI avatar is an AI-generated digital presenter that reads any script. Captions builds avatars with Mirage Avatar X, a proprietary model. Mirage Avatar X generates voice, expression, and movement together as one performance. The result looks and sounds human, not like a photo with a moving mouth.
What makes Mirage Avatar X different?
Most "AI avatars" are still photos with a lip-sync overlay. That makes avatars look stiff, with dead eyes and robotic timing. Mirage Avatar X generates the entire avatar performance at once, including voice, micro-expressions, eye contact and body language. Your avatar delivers your script the same way a human would.
How do I make a video with an AI avatar?
It's only a few steps in Captions. Pick an avatar, paste or generate a script, then create the full video at once. You'll have a finished video in minutes. No camera, no editing skills required. You can download the video directly or share straight to top social platforms.
Can I use Captions’ avatars commercially?
Yes. Captions avatars can be used for personal or professional projects, including commercial content. All usage must follow our content guidelines, which prohibit harmful, misleading, or defamatory material. You can learn more in our terms.
What's the best AI avatar generator?
The best generators make avatars that actually look human. Captions' avatars are powered by Mirage Avatar X, an in-house model developed to make comprehensive avatar performances. It generates motion, audio and expression together, making avatars look more lifelike than other models do.
AI avatar vs. AI twin. What's the difference?
An AI avatar is a ready-made or prompt-built presenter that isn't a real person. An AI twin is a digital version of you, made from a short recording. If you want yourself on screen, you can create an AI twin in Captions.
How does an AI talking avatar work in Captions?
Captions avatars are powered by Mirage Avatar X, our proprietary AI model for video generation. You can use them to make any kind of talking head video, from thought leadership to video ads. Just pick the avatar you want to use, and it will deliver any script you pick. You can adjust other details like captions, editing style and length once it generates.
How can I make a video without showing my face?
You have two main options. You can either create a faceless video, or you can use a video avatar to present for you. With AI avatars, you get the benefit of someone delivering your script and message, without having to show your own face or film it yourself. If you don't want to show any kind of face at all, faceless voiceovers are the better option for you.
Can I create an avatar of myself?
Yes, you can make an AI twin. Just make a short recording and Captions creates a digital twin for you, with your likeness and speech patterns. You can create multiple twins and style them with different looks, outfits, and settings, giving you flexibility across your content.
Which AI can create a realistic person for my videos?
Captions can generate realistic people for your videos using AI avatars. With Captions, you can either choose from a library of AI avatars or generate a new character from a prompt. You can also create a digital twin based on a real person using a short video clip. These avatars deliver natural voice, expressions, and movement designed for modern video content.
