Checksub

AI subtitles, dubbing and 200-language video translation in one browser editor

Automatic subtitling and animation

Generates accurate captions with AI, then lets you apply dozens of style presets and animations, including one-click karaoke effects, before exporting burned-in video or subtitle files.

Translation into 200+ languages

Machine translation built specifically for subtitles, so line lengths and timing stay readable instead of copying a generic document translator.

AI dubbing with voice isolation

Separates music and background noise from the original voices, then replaces only the speech with realistic AI dubbing so the audio atmosphere is preserved.

Voice cloning in 30 languages

Clone a speaker's voice from a sample and use it to replace the original voice-over across dozens of languages with a natural delivery.
