Checksub

Checksub is a subtitle generator and AI dubbing platform for video. It transcribes speech, translates subtitles into around 200 languages, and can dub videos into other languages with voice cloning, voice isolation that keeps the original music and background audio, and a generated voice for each speaker. A lip sync feature is in beta. It is used by creators, marketing and training teams, and organizations that want to publish video in many languages. Subtitles can be generated automatically or synchronized from an existing script, styled with dozens of settings and animations such as a karaoke effect, and burned into the video or exported as a subtitle file in formats like SRT and VTT. An online editor lets you correct and regenerate any sentence after the AI pass. Higher plans connect YouTube channels, and the Enterprise plan adds API access and an account manager. Pricing is credit based, and unused monthly credits are kept for six months with an active subscription. With monthly billing, Junior is $18 a month for 2 hours of credits with subtitle export and one translation per project. Starter is $59 a month for 5 hours and adds AI dubbing, voice cloning, lip sync in beta and no watermark. Annual billing lists Junior at $12 a month and Starter at $48 a month. Enterprise is custom, from $299 a month billed yearly. A free trial is offered.
