Checksub
AI subtitles, translation, and dubbing for video creators.
About
Checksub is a French AI platform for subtitle creation, translation, and AI dubbing founded in 2017. It converts audio or scripts into synchronized subtitles, translates them across 200+ languages with a workflow that first transcribes the original audio for higher accuracy, and dubs videos with realistic AI voices, voice cloning, voice isolation, and lip-sync while preserving background audio.
The platform includes a sentence-level online editor for precise alignment, customizable subtitle styles with burn-in and karaoke animations, team collaboration tools with roles and review workflows, YouTube channel connections, and API access on higher tiers. It is used by translation agencies, video creators, and global brands for localization, e-learning, and social media publishing.
Honest limitations: full functionality requires a subscription starting at $18 per month for the Junior plan, with AI dubbing and voice cloning gated behind the $59 Starter tier. Reviewers note translation quality varies by language pair, voice cloning capabilities are limited compared to dedicated voice platforms, and everything depends on an internet connection with no offline mode.
