  Captions is an AI-powered video creation and editing platform developed by Mirage, a New
  York-based AI research and product company. The platform enables creators and businesses to
  generate, edit, caption, dub, and translate talking-head videos at scale using generative AI.
  The Captions API — served under the Mirage API umbrella — exposes capabilities for automated
  video captioning, AI Creator video generation (using community avatars or personal AI Twins),
  AI Ads video generation, and bulk video management, all authenticated via API key and billed on
  a per-second-of-video credit model. Captions supports output in 30+ languages with automatic
  language detection, lip-sync dubbing, and direct publishing integrations for TikTok, Instagram,
  and YouTube.
