Category	Video	Voice
Pricing	Credit-based, free trial	Free tier + pay-as-you-go
Best for	Anyone who wants top-tier video quality for less.	Therapy apps, customer service, any voice agent where emotion matters.
Strengths	Very strong motion + physics Often beats Runway on realism Great price	Detects + mirrors emotional tone EVI (Empathic Voice Interface) feels different Expressive voice output
Weaknesses	UX is rough for English speakers Queue times	Niche use case Pricing ramps fast
