Lip Sync AI is a web-based video tool for creating natural-looking speaking videos from video, audio, and portrait images. It is designed for creators, educators, marketers, and localization teams who want to produce dubbed or voice-driven content without a complex editing workflow.
Users can upload a source video and an audio track to generate synchronized mouth movements, or use a portrait photo to create a talking avatar. The platform also supports multilingual dubbing, allowing users to adapt content for different languages while keeping facial performance more consistent. For more complex scenes, Lip Sync AI includes multi-speaker detection to help align speech with the correct on-screen person. It also offers preview and export options, including high-resolution output up to 4K.
Lip Sync AI can be used for video dubbing, educational content, social media clips, talking avatar videos, and multilingual localization projects. Its main goal is to make speaking video creation faster and easier for users who need a practical browser-based workflow.
