AI Avatar Video Generator
An AI avatar speaks your script on-camera without a studio, talent fee, or shoot day. Oakgen's avatar pipeline generates or accepts a presenter photo, animates it to deliver your message with synchronized lip movement and natural expressions, and adds a voice from ElevenLabs' library or your own clone. The result is a polished, repeatable presenter that works across ads, onboarding videos, explainers, and social content.

Frequently asked questions
What is an AI avatar video?
An AI avatar video features a computer-generated or AI-animated presenter delivering a script with synchronized speech, facial expressions, and natural motion — replacing on-camera talent for ads, courses, and social video.
Can I generate a realistic human avatar without using a real person's face?
Yes. Use FLUX or Nano Banana Pro to generate a diverse, realistic human portrait from text, then animate it with Talking Photo. You own the generated face and can use it commercially on paid plans.
How long can AI avatar videos be?
Oakgen's avatar tool handles scripts of any length, but generates in segments for best quality. For longer videos, generate 30-90 second segments and combine in your video editor.
Can the avatar speak multiple languages?
Yes. ElevenLabs v3 supports 40+ languages with voice cloning. Generate the same avatar script in English, Spanish, Arabic, and Japanese using the same voice clone for consistent brand delivery across markets.
Is AI avatar video compliant with ad platform policies?
TikTok, Meta, and Google allow AI-generated avatar ads with appropriate disclosure. Requirements vary by platform and campaign type. Review current platform guidelines before running at scale.
