AI Avatar Generator
Pick an AI actor, describe the video or write the exact script, and generate a talking avatar video. Realistic UGC for creator-style ads, or Exact Script for word-perfect lip-sync.
- Pro: Looks like real creator content — photoreal, social-native, high trust.
- Trade-off: You describe the video — the actor won’t say your script word-for-word.
Powered by Kling 3.0 Pro
Best for: authentic social ads, testimonials, "creator-style" content where the look matters more than exact words.
- Pro: Type your script — the actor speaks it word-for-word, perfectly lip-synced.
- Trade-off: Looks slightly more AI-generated than real UGC.
Powered by Omnihuman 1.5
Best for: promo codes, legal copy, brand mandates, anything where the wording must be exact.

What you can make
Realistic UGC

Exact Script
Write the script and the actor says it word-for-word with Omnihuman lip-sync. Ideal for offers, codes, and claims.
Dozens of AI actors
Pick from a gallery of actors by look, age, and setting, and render the same brief with several at once.
Your voice or ours
Text-to-speech in the actor’s voice, or speech-to-speech from your own recording for exact delivery.

What is an AI avatar generator?
An AI avatar generator creates a video of a realistic digital person speaking to camera. For advertisers the use case is UGC-style ads: the selfie-framed, creator-delivered format that consistently earns the cheapest attention on Meta and TikTok, without recruiting, briefing, and paying individual creators for every variation.
There are two ways to make one, and the choice matters. Realistic UGC uses cinematic video models like Kling 3.0 Pro to render a photoreal creator who riffs on your brief, which looks the most authentic but paraphrases your words. Exact Script uses a lip-sync model, Omnihuman 1.5, so the actor speaks your script word-for-word, which is what you want for promo codes, legal lines, and brand-mandated claims.
AdStellar gives you both in the same composer, a gallery of AI actors, the option to create a custom actor from your own footage, and a direct path from the render to a live Meta ad.
