HappyHorse AI

HappyHorse AI is a free online AI video generator for turning text descriptions or uploaded images into cinematic videos. It is built around the HappyHorse 1.0 model, described as a 15-billion-parameter open-source system, and the site says it creates 1080p video with synchronized audio and seven-language lip-sync. The page also highlights a rank of 1 on the Artificial Analysis Video Arena.

Its feature set includes text-to-video and image-to-video workflows, with plain-language prompts or image uploads as starting points. The interface shows multiple aspect ratios, including 16:9, 9:16, 1:1, 4:3, and 3:4, and durations from 3 seconds to 15 seconds. It also advertises 50+ visual styles, multiple variants from a single prompt, multi-shot storytelling, and motion synthesis. Prompts can be written in English or Chinese, and the generated videos are described as suitable for client work, advertising, social content, e-commerce, content creation, presentations, and creative projects, with full commercial rights and no attribution required.

HappyHorse AI is delivered as a web-based service. The page says no sign-up is needed and no credit card is required to start, with 20 free credits included. Its pricing is presented as one-time credit packs rather than a subscription, and the listed packs are valid for 30 days after purchase. The pricing section names Small, Medium, and Large packs, each tied to 1080p HD resolution, all aspect ratios, and full commercial rights, with higher tiers adding priority processing, priority support, early access to new models, or dedicated support. The site also mentions preview and download after generation.
