What is Checksub?
Checksub is a web platform that uses AI to generate subtitles, translate them and dub videos into other languages. It is aimed at businesses, creators and organizations that publish video and want to reach viewers in more languages.
The site describes three product areas: subtitles, translation and AI dubbing. The company says it spent 6 years developing its subtitling platform, and its homepage reports more than 153,000 videos processed.
How does Checksub work?
A user uploads a video and Checksub transcribes the audio into captions in the original language. That step always comes first, because the company says translating directly from audio would produce lower quality and complicate edits across languages.
The captions are then translated, and for dubbing Checksub generates a voice for each speaker. Pre-generated subtitles appear within a few minutes, depending on video length and size, and the online editor lets users edit and regenerate any sentence.
Key features of Checksub
On the subtitle side, Checksub offers automatic subtitles, conversion of an existing script into synchronized subtitles, dozens of style settings, one-click karaoke animation, pre-built templates and custom fonts. Videos can be exported with burned-in subtitles or as SRT or VTT files.
For dubbing, voice isolation separates music and noise from speech so only the voice is replaced. Voice cloning works in 30 languages, and lip-sync is available in beta. Translation covers more than 200 languages, and Enterprise adds API access.
