Make a realistic AI twin for videos
Once you have a personal avatar in Captions, you'll never need to record again. Create a realistic AI twin that looks and sounds just like you. It's you, on demand.
How it works
Captions generates your AI twin from a short recording. Your twin will share your same behaviors and voice, so it's immediately recognizable as you. All avatars are powered by Mirage Avatar X, our proprietary model.
Post more consistently with your AI twin
Like looking in a mirror
Your AI twin captures the details that make you unmistakably you, like expressions and tone.
Show up everywhere
From social media to presentations, your AI twin creates natural-looking videos in both vertical and horizontal formats.
Customize for any topic
Your twin can perform any kind of video script. Change outfits and backgrounds, or even languages.

Frequently asked questions
What’s a digital twin in AI?
A digital AI twin is a generated character that looks and sounds just like an existing person. The technology uses AI to recreate a person’s likeness and mannerisms. You typically create AI twins from selfies or a short recorded clip.
Why should I get an AI twin?
People use AI twins to make videos faster or more consistently. Because you can generate new footage with your digital avatar, it’s quicker and cheaper than traditional video production.
How realistic will my AI twin look?
Captions' AI twin technology produces realistic video that preserves your natural expressions, voice quality, and movement. It's powered by Mirage Avatar X, an in-house model specifically designed to create hyperrealistic AI avatars. Because Mirage Avatar X generates audio, video, and movement together, it makes the final output look more realistic than other models on the market. Most audiences won't be able to tell the difference between a video you filmed live and a video using your Captions AI twin.
Is an AI twin the same as a deepfake?
No. A deepfake uses AI to put someone's likeness into content without their knowledge or consent. An AI twin is built from your own recording, with your explicit permission, for your own use. It's a production tool you control, not a synthetic impersonation of you.
Can AI twins also clone my voice?
Yes, and that's an important detail to make your AI twin really seem like you. When you record your sample footage in Captions, it uses your voice tone and patterns to inform your twin. Captions will apply those same patterns to new videos that you make using the AI twin. For the best result, make sure you’re in a quiet space when you record your sample footage.
What’s the best AI twin creator?
The best AI twin creator lets you clone your appearance quickly and accurately. You typically upload an image of yourself or film a short video, and the AI takes it from there. This software should perfectly recreate you, including natural movements and facial expressions. Some tools also let you generate an AI voiceover with your tone and accent. Platforms like Captions take AI twin creation further, letting you swap outfits and backgrounds with a simple prompt.
What's the difference between an AI twin and AI avatar?
An AI twin is a digital version of you, built from your recording. AI avatars are customizable AI actors that are fully generated using AI.
How do I create an AI avatar of myself?
Captions offers three ways to make your digital twin. You can upload existing footage, record a short new video, or add a selfie. For the highest-quality match, we recommend using video footage. That way, Captions can better capture your natural movements and voice quality. If you prefer to use a photo, you can create an AI twin from a selfie. Simply snap a photo and upload it to the Captions app. In moments, the AI will transform your selfie into a realistic, moving avatar you can use in any content.
Can I create multiple variations of my AI twin with Captions?
Captions lets you generate many variations of your AI twin. Once you pick a twin you like, you can change the background, outfits, or even add products. Localization is also a breeze with automatic translations, subtitles, and custom captions.
