How the Seedance AI Generator Works
Pick a Mode
Start from a text description or an existing image. The builder adapts its fields to whichever mode you choose so the prompt is structured correctly.
Compose the Shot
Layer in camera movement, style, lighting, aspect ratio, and duration. Watch the optimized prompt update live as you adjust each control.
Run It Anywhere
Copy the prompt or JSON and generate on the Seedance provider of your choice. The same request works across fal, Replicate, PiAPI, and BytePlus ModelArk.
Seedance AI Generator FAQ
Is the Seedance prompt builder free?
Yes, the builder is completely free and runs entirely in your browser. You only pay your API provider when you actually render a video, which is typically a few cents per short clip.
Do I need an account to use it?
No account or sign-up is needed to build prompts and API requests. You will need an API key from a Seedance provider only at the point where you send the request to generate the actual video.
Which providers support Seedance 2.5?
Seedance 2.5 is available through ByteDance's BytePlus ModelArk directly, and through third-party gateways such as fal.ai, Replicate, PiAPI, and Kie. Pricing and resolution caps vary by provider.
