Happy Horse AI

Happy Horse AI is a browser-based AI video generation platform for creators, marketers, developers, and production teams. Its Happy Horse 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 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 before submission. A unified workspace organizes task status, previews, completed videos, and downloads, while the Happy Horse API lets developers submit supported generation tasks, monitor status, and integrate video creation into apps, SaaS products, internal tools, and repeatable content pipelines.
