What is Checksub?

Checksub is an AI-powered platform that automatically generates subtitles, translates videos into more than 200 languages, and provides AI dubbing with realistic voices. It offers advanced editing tools, customizable subtitle styles, and supports voice cloning and lip-sync features. The platform is designed for content creators, companies, and organizations to expand their video reach globally.

How to use Checksub?

  • Start by signing up for a free trial, which includes credits to translate 1 hour of video. Upload your video, and the platform will automatically generate subtitles in the original language. You can then translate the subtitles into multiple languages or use AI dubbing to replace the voiceover. Use the online editor to refine subtitles, adjust styles, and export the final video or subtitle files.
