What Checksub is
Checksub is a video subtitling, translation, dubbing, and voice-over service available on the web, through an API, and as an extension. It can create subtitles automatically or synchronize subtitles from a script, then translate them into 200 languages. Its dubbing replaces the original voice while preserving the background audio; Checksub also says users can substitute a cloned voice in 30 languages. After generation, the online editor lets users revise and regenerate sentences. Subtitles can be burned into exported videos and styled with animations, including karaoke effects.
The service supports publishing translated videos to YouTube, and its Starter plan connects one channel. Listed integrations include YouTube, Twitch, Google Drive, Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro. Credit use varies by task: subtitles use one credit minute per video minute, dubbing uses three, and lip-sync uses five. Checksub also offers a free YouTube subtitle downloader and a Chrome extension for downloading subtitles. The company was founded in 2017 and is headquartered in France. A free plan and free trial are available; paid plans include email support, while Enterprise customers can request a demo or quote.
