LivePortrait AI is an AI tool developed by the Kuaishou team. Its core capability is to transform a single static portrait photo, when paired with a driving video or audio track, into a realistic dynamic portrait animation video.
The tool is offered online with a free trial quota and a paid subscription model. Details on quotas and plans can be found on its official platform.
It supports a wide range of static images as input, including real photos, anime characters, artwork, and even pet portraits.
Users can drive the portrait animation by uploading a custom video containing the target actions, or by choosing from preset motion templates provided on the platform.
Generation time depends on task complexity and system load, typically from a few seconds to a few minutes.
In addition to online usage, the project is open-source and supports local deployment, so users can run it on their own devices to avoid uploading sensitive data.
