LongCat Avatar

LongCat Avatar is a state-of-the-art AI avatar video generator focused on creating realistic, long-form talking videos from audio, text, and image inputs. Unlike many short-clip AI tools, it is designed to maintain identity consistency and visual quality over extended sequences, ensuring that generated avatars look stable and cohesive even in long videos. The platform supports multiple input modes—including Audio-Text-to-Video (AT2V) and Audio-Text-Image-to-Video (ATI2V)—allowing users to upload a portrait photo, audio track, and optional text prompt to produce expressive, lifelike performances with precise lip synchronization, natural facial expressions, and smooth human motion. LongCat Avatar outputs HD videos up to 720p and can handle multi-character interactions. It’s suitable for a range of use cases such as content creation, education, marketing, podcast visualization, and corporate presentations. With a flexible, credit-based pricing model and intuitive upload-and-generate workflow, LongCat Avatar makes advanced avatar video generation accessible to creators, brands, and media professionals.
