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 a subject, action, camera movement, scene, lighting, and visual style, or upload images and reference materials to guide character, composition, and style consistency. Depending on the selected generation mode, it offers 720P or 1080P output, durations from 3 to 15 seconds, optional audio, aspect-ratio controls, and clear credit estimates before submission. A unified workspace keeps task status, previews, completed videos, and downloads organized. Developers can create API keys and use the documented Happy Horse API to submit supported generation tasks, monitor their status, and integrate video creation into apps, SaaS products, internal tools, and repeatable content pipelines.
