What Checksub is
Checksub provides AI-powered subtitles, dubbing and voice-over for videos through web, API and extension platforms. It can create automatic subtitles or synchronize a script to video, and says it can generate subtitle translations in 200 languages. Dubbing replaces the original voice while retaining background audio; users can also replace voice-over with a cloned voice in 30 languages. The online editor lets users revise and regenerate sentences after subtitle or dubbing generation. Subtitles can be burned into exported videos and styled with animations, including karaoke effects. Translated videos can be published to YouTube, and the Starter plan connects one channel. Listed tools include YouTube, Twitch, Google Drive, Adobe Premiere Pro, DaVinci Resolve and Final Cut Pro. Credit use is one credit minute per video minute for subtitles, three for dubbing and five for lip-sync. A free plan and trial are available, as is a free YouTube subtitle downloader and Chrome extension. Junior costs $18 a month, billed monthly; Starter costs $59 a month, billed monthly. Checksub was founded in 2017 and is headquartered in France.
