Happy Horse AI

Happy Horse AI is a browser-based AI video generation platform for creators, marketers, developers, and production teams. Its HappyHorse 1.1 model supports text-to-video, image-to-video, and reference-to-video workflows. Users can describe subjects, actions, camera movement, scenes, lighting, and visual style, or upload images and reference materials to guide consistency. Depending on the mode, the platform offers 720P or 1080P output, 3–15 second durations, optional audio, aspect-ratio controls, and clear credit estimates. A unified workspace organizes task status, previews, completed videos, and downloads. Developers can create API keys and integrate supported generation tasks into apps and repeatable content workflows.
