What app is used for the AI zombie trend?
There is no single official app. The trend videos online come from many different AI video models and apps. Zombie Hug uses Seedance 2.0 Mini by ByteDance for every video. Read how the AI zombie trend works for the story and the ways to make one.
Video generation
Seedance 2.0 Mini by ByteDance makes your 15-second, 9:16, 720p video with sound. The model gets your two photos and a fixed story text. You cannot write your own prompt.
How an order goes to the models
- We send every order to Seedance 2.0 Mini by ByteDance through our main API provider.
- If that fails or is slow, we send the same order to the same model (Seedance 2.0 Mini) through a second provider, at 720p.
- You do not pay more for a retry. If the video fails, it costs you nothing.
Content check
An automated NSFW classifier checks both photos after upload and every video before delivery. If it blocks content or cannot finish, we do not deliver it.
Free preview
Before you pay, the preview shows the photo of the person who turns with a cold color tint. Your browser makes the tint. No AI model makes it, and it is not a sample of the final video.
What the model services get
- They get your two photos through private links that expire.
- They do not get your email address or your payment details.
We do not use your photos or videos to train AI models. Read the Privacy Policy for retention times.
