Avatar quality is inconsistent - some look natural, others feel awkward
Editing capabilities are basic with no complex transitions or timeline control
Template library is small compared to competitors like Synthesia
Screen recording feature feels like an afterthought and underperforms dedicated tools
Less common languages in text-to-speech can sound noticeably robotic

Video translation with lip-sync matching is genuinely revolutionary - nothing else comes close for multilingual video content
Custom avatar quality has improved dramatically and produces videos that pass for professional talking-head content at a glance
Template-driven workflow makes video creation accessible to marketing teams with zero video production experience
API and automation capabilities enable personalized video at scale - thousands of custom videos from data inputs
Interactive avatar streaming opens entirely new use cases like AI-powered customer support and virtual presentations

Avatar videos are noticeably AI-generated to attentive viewers, which limits use in contexts demanding authenticity
No creative video generation capabilities - this is a business tool, not an artistic one
Custom avatar creation requires following specific filming guidelines and quality varies based on input footage
