Cons

The subscription pricing is positioned at a premium enterprise level, making it cost-prohibitive for individual creators, freelancers, and small businesses with limited video production budgets.
Custom avatar creation requires an initial recording session and setup process that can take several days, and the resulting avatar quality depends heavily on the quality of the original recording conditions.
The platform is primarily designed for enterprise and business communication use cases, which means casual or creative content creators may find the feature set and pricing structure poorly suited to their needs.

Pricing starts relatively high compared to competitors, putting it out of reach for individual creators and small businesses on tight budgets.
Avatar movements and expressions, while improved, can still fall into the uncanny valley for viewers who are sensitive to subtle cues.
Creative customization is limited compared to traditional video editing suites, making it less suitable for highly artistic or cinematic content.
