OmniHuman AI is a web-based AI avatar generator that creates realistic digital human videos with perfect lip sync from a single photo and audio file.
What is OmniHuman AI?
OmniHuman AI is a web-based platform that generates realistic digital human videos from a single portrait photo and an audio recording. It accepts photos up to 10 MB in JPG, PNG, or WEBP format and audio files up to 15 seconds in MP3, WAV, or M4A format, or you can use built-in text-to-speech to create the audio. The output is a video with perfect lip synchronization, natural facial expressions, and head movements. The tool runs entirely in the browser — no software download required. The company behind OmniHuman AI is not named on the site, but the service is available at omnihuman-ai.org.
