Vidnoz is a free online tool that allows users to create talking avatar videos. It uses AI technology to generate realistic lip-syncing videos from text scripts. Users can upload or select a photo of an avatar, write a script, and choose a language and voice. The tool then converts the script into speech and creates a video with the avatar speaking the text. It can be used for various purposes such as marketing, education, and customer support. The videos can be generated, downloaded, and shared for free.
