Cons

Strict content filters can sometimes interrupt conversations unexpectedly, even in non-problematic contexts, which can break immersion and frustrate users seeking creative freedom.
Characters can fall into repetitive response patterns during extended conversations, occasionally recycling similar phrases or narrative structures across sessions.
Since the platform prioritizes personality and engagement over factual accuracy, it should not be relied upon for research, homework, or any task requiring truthful information.

Paid plans are required for watermark-free exports and professional-quality output, and pricing can add up for teams producing high volumes of video content.
While the free tier allows experimentation, the one-minute video limit and watermark make it unsuitable for any production use, functioning purely as a trial.
Avatar realism, though impressive, can still trigger uncanny valley reactions in some viewers, particularly during extended monologues or when avatars attempt complex emotional expressions.
