About
Hedra is an AI character video generation platform founded in 2024 in San Francisco, built to enable anyone to create high-quality talking character videos from text, audio, or image inputs. The company was founded by former researchers with expertise in generative video, audio synthesis, and multimodal AI, and launched publicly with its Character-1 model — a system capable of generating expressive, lip-synced character animations with cinematic quality from a single portrait image and audio input. Hedra's technology is designed for content creators, marketers, educators, and game developers who need to produce video content at scale without live-action filming.\n\nHedra's product suite includes Character-3, its flagship model that supports long-form character videos up to 10 minutes in length — a significant technical achievement in a space where most models are limited to a few seconds of coherent output. The platform also offers Live Avatars, a real-time interactive character generation feature priced at $0.05 per minute, enabling use cases such as virtual presenters, interactive AI personas, and real-time video synthesis for live applications. Hedra is available as a web platform and through an API, allowing developers to integrate character video generation into their own products.\n\nHedra has grown to more than 3 million users who have collectively generated over 10 million videos on the platform, demonstrating strong organic traction in the rapidly expanding AI video market. The company raised $44M in total funding to accelerate model development and platform scaling. Hedra competes with HeyGen, Synthesia, and D-ID in the AI avatar video segment, differentiating through its long-form generation capability and real-time avatar technology.
