Users can plug in their own API keys for top-tier models like Google Gemini, OpenAI, or Anthropic to generate highly accurate, context-aware translations in multiple languages.

Real-Time Workflow

Offers instant subtitle previews over the video, smart refinement tools (to rephrase or shorten lines), and instant export to industry-standard formats like .SRT.
