What they are
Synthesia
Synthesia generates studio-quality videos using AI avatars that lip-sync to a typed script, with no camera, microphone, or editing software required. It targets corporate trainers, marketers, and course creators who need to produce multilingual video content at scale. The output looks polished but has a recognizable AI avatar aesthetic that some audiences find less engaging than real presenters. Pricing starts at $14 per month on the Starter plan.
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.
