The short version

  • Only HeyGen has a free tier, so it costs nothing to try first.
  • Each has a real cost: HeyGen avatar movements feel unnatural in longer videos and repetitive with limited emotional expression, appearing stiff and robotic after 60 seconds; Mmhmm renamed to Airtime and split into four separate tools, Camera, Recorder, Creator and Stacks, rather than the single app the mmhmm name refers to
  • They diverge on capability: HeyGen covers AI avatars, Mmhmm covers Custom layouts.
