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.

AI-powered browser video editing and content creation for teams
Turn a short text prompt into a multi-layer video project with voiceover, visuals, music, subtitles, and characters that you can then refine in the editor.
Generate captions automatically, translate subtitles into 60+ languages, and dub dialogue into 40+ languages for global distribution.
Automatically remove silences and filler gaps from footage and clean up background noise and loudness in a single pass.
Edit on a shared timeline with real-time collaboration, comments, project link sharing, brand kits, and custom fonts.
