Wizstar helps founders, creators, and makers build an expressive, accurate digital ambassador that looks and moves like you. It gestures naturally, interacts with objects, and maintains precise lip sync—even during head turns or things in front of your face. Create product updates, training, localized videos, and branded content without being on camera every time. Bring your digital presence to life and scale it across markets, languages, and channels.

Hi Product Hunt! 👋 I run marketing for the team at WizStar.
WizStar creates digital ambassadors that don't just look like you —
they move and act like professional actors.
Many AI avatars can speak, but feel stiff. They stare straight into the camera, repeat limited movements, and lack coordination between the face and body.
WizStar focuses on natural expressiveness. Your digital ambassador turns its head, gestures, and interacts with objects. It coordinates facial, neck, and full-body movements—so it doesn’t just talk like you, it truly comes to life.
For founders, their Wizstar avatar can act as their public ambassador, helping to stay active across everyday social channels. Or, when a last minute change threatens to scuttle a launch, a WizStar avatar can be used to create a compelling, expressive launch video in minutes.
Key capabilities:
👄 Precise lip sync — Maintains accuracy even with object covering the mouth or face
🎥 Full-angle adaptability — Natural results from side, upward, and downward angles
🧍 Smooth full-body motion — Synchronized facial, neck, and body movements
⏱️ Long-video input — Supports source videos up to 5 minutes or 200MB
To start, simply upload a photo or video, add a voice sample, write the script, and generate your avatar video in seconds—without repeated filming or a complex setup.
WizStar is ideal for marketing, social content, product demos, sales, training, and multilingual localization. We also support custom avatar clothing and offer a diverse library of globally localized digital avatars. Create your digital asset once, then reuse it across languages, channels, and scenarios.
We’d love to hear your thoughts: what would you create with a truly expressive digital ambassador that moves like you? 🚀

I’ve made enough hackathon videos to know the final boss isn’t shipping the product — it’s recording a coherent maker video while everything is still changing underneath you!
For Firstpass (my entry into the @Glaze by Raycast Awards) I wanted to but was unable to put together a maker video to support my launch.
Then I met the Wizstar team and they showed me their founder ambassador app. With just a sample photo and video call of me, they created an AI avatar that speaks, turns my head, gestures, and delivers a launch pitch without the usual stiff, staring-your-down-without-blinking Zuckbergian vibe.
And then when the script changes at the eleventh hour (which it inevitably will!), there's no stressful reshoot.
Just generate another take, and publish.
As far as plausibly realistic avatars that can traverse the uncanny valley — I have to say, I'm pretty impressed with what the Wizstar team produced here! Maybe next time I enter a hackathon, I'll send my maker ambassador instead! 🤖

How do the lip movements of AI avatar such naturalness? What is the underlying technology?
Wizstar
@axelkane I’m glad to answer this question～
Wizstar innovatively adopts a two‑stage lip‑driving solution
Stage 1: Decode the genuine motions behind audio
The AI first decomposes speech audio, mouth‑opening‑closing movements, and head poses into three independent sets of data. After parsing the audio separately, it precisely drives the 3D facial mouth, facial muscles and head rotation. This eliminates lip‑sync glitches and cross‑interference that commonly occur during head turning.
Stage 2: Reconstruct authentic fine‑grained facial details
When rendering frames, the AI no longer needs to repeatedly infer mouth shapes. Instead, it focuses on reconstructing realistic facial textures, subtle expressions and visual quality. This mitigates artifacts including flickering outputs, blurriness and distortion, delivering human‑like motion performance.
Through the synergy of the two stages, Wizstar achieves an optimal balance among naturalness, visual clarity and generation efficiency.
The natural gestures and lip sync are what caught my attention. Those small details can make an avatar feel much more believable.

@lucyjane Appreciate that! Keeping accurate lip sync was a non-negotiable from day one. It means a lot to hear that it resonates🙌
I like the idea of creating contant once and adapting it for different markets instead of recording everything again.
Wizstar
@desire_waterman Thank you so much! That was the design principle from day one—the tool should create content once, not record everything again. Appreciate you calling that out!!
This could save creator a lot of repeated camera time. I'd probably use it most for short announcements and tutorial video.
Wizstar
@melina_cross Thank you so much! 😊You nailed exactly why we built it this way!
The precise lip sync during head turns sounds like one of those details you only notice when it goes wrong.
Wizstar
@robertspencer Exactly! It’s one of those invisible details that makes a huge difference to how natural an avatar feels. The moment the lip sync breaks during a head turn or mouth occlusion, the illusion is gone. That’s why maintaining accuracy through movement is such an important part of Wizstar. Thanks for noticing!
