What they are
HeyGen
HeyGen generates studio-quality videos using AI avatars and text-to-speech voices, so creators and marketers can produce talking-head content without filming themselves. It supports over 175 languages and lets you clone your own voice and likeness. Teams use it for product explainers, onboarding videos, and localized content at scale. The avatar quality is impressive for scripted material, but unscripted or conversational styles still feel noticeably synthetic.
Udio
Udio is an AI music generation tool that produces complete songs, including vocals and instrumentation, from a text description. It is used by content creators, podcasters, indie game developers, and musicians looking for quick backing tracks or original compositions. The output quality is impressive for AI-generated audio, though the tool gives you limited fine-grained control over individual stems or arrangement details.
