AI lip sync tools are no longer just for film studios. They help anyone who works with talking head video – from course creators to architects explaining sustainable designs – match mouth movements to new audio so translated or updated content still looks natural. Here are eight notable lip sync tools, with Rask AI at the top of the list.

Lip sync used to be an expensive, manual part of post production, but AI has turned it into something that even small teams can deploy to make multilingual or updated videos look natural. Some tools focus on simple social clips, others on developer workflows or complex multi character scenes, and a few, like Rask AI, combine lip sync directly with translation, dubbing, and subtitles so you can turn a single source video into convincing localized versions at scale.
