AI subtitles, dubbing and 200-language video translation in one browser editor
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.
Machine translation built specifically for subtitles, so line lengths and timing stay readable instead of copying a generic document translator.
Separates music and background noise from the original voices, then replaces only the speech with realistic AI dubbing so the audio atmosphere is preserved.
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.
Learn languages from real videos with word-by-word subtitles
Every word is transcribed with its own timing so it highlights exactly as it is spoken, with the meaning in that sentence displayed above it.
A no-signup test estimates how many words you know and places you from A1 to C2, then recommends videos matched to that level.
Tap any word for its dictionary form, part of speech, frequency, in-sentence meaning and a note explaining the grammar, slang or expression.
Show translations over every word as a beginner, switch to only unknown words as you improve, or turn them off completely.
