Why use AI avatars?

AI avatar videos are proven to drive results, cost less to produce, and scale to any language.

Your audience won't disengage

A UCL research report studying 500 adult learners found no significant difference in engagement or retention between an AI avatar video and human instructor video. Viewers completed the AI version around 20% faster.

Cut production costs, not quality

An independent peer-reviewed study at USC Marshall tested AI avatar videos against human presenters across 250+ professionals and found identical knowledge transfer across both groups.

Scale across every language

With AI avatars, the same video publishes across 160+ languages without a new recording. In our 2026 AI in L&D Report, 54% of respondents said global localization is where they expect AI to deliver the most value.

How to generate your own AI avatar

1. Upload a photo or short video

   Simply upload a high-quality photo for the quickest result or record a brief video to capture your avatar’s natural and lifelike movements.

2. Select your voice and record consent

   Optionally clone your unique voice for a perfect match or select a stock voice for your avatar before recording a live consent statement.

3. Generate and use your custom avatar

   Once processing finishes, your avatar is ready to narrate any script in over one hundred languages with custom outfits and professional backgrounds.
