Ubique

The idea is nice, but unfortunately the product at the current state is very incomplete and there is no public roadmap nor any transparency which feature can be expected when. Currently just English and French are supported. German support was announced for February, but not any effort can be seen here until today. At the moment videos can just be rendered with a website or video background, not just the speaker/voice clone without any addition - which seems different when you see the sample on their home site. I'm not sure whether this app will be still available in some months - I'll probably do a refund.
